Ojo O, Olusola RE, Ojo OO. Spilanthes filicaulis (Schumach. &Thonn.) C. D. Adams: An insights into ethnopharmacologically important but scientifically understudied species. ANNALES PHARMACEUTIQUES FRANÇAISES 2024:S0003-4509(24)00093-2. [PMID: 38821482 DOI: 10.1016/j.pharma.2024.05.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2024] [Revised: 05/26/2024] [Accepted: 05/27/2024] [Indexed: 06/02/2024]
Abstract
Spilanthes filicaulis (Schumach. & Thonn.) C. D. Adams is synonymous to Acmella caulirhiza Delile. The plant, also known as cock's eye or African cress, is a medicinal herb that belongs to the Asteraceae family. In this paper, the holistic and current applications of S. filicaulis were synthesized and critically discussed by summarizing, for the first time, its botany, traditional medicinal uses, active components, and pharmacological properties. We employed the databases of ScienceDirect, Scopus, Online Wiley library, PubMed, and Google Scholar to retrieve data on S. filicaulis from inception till February 2024, resulting in more than 70 electronic references. Based on literature reports, S. filicaulis has rich ethnopharmacological uses in different disease areas but their scientific validations are still in early stage, or not verified yet. In general, 16 phytochemicals have been identified so far. They include spilanthol, piperine, erucic acid, and isoquinoline derivative among others. The plant extracts possess anticancer, antioxidant, antimicrobial, anti-inflammatory, hepato-protective, anthelminthic, and analgesic activities. In the future, the phytochemical components, and biological activities of S. filicaulis need to be further investigated. Similarly, mechanistic studies need to be incorporated to the biological testing, to uncover the modes of actions of the species extracts and active components. Considering the species' rich ethnopharmacological applications, and the dearth of robust and established toxicity reports, the study on the safety of S. filicaulis would be an interesting and rewarding approach for further research.

Protective Potential of Methanol Extract of Drymaria cordata Willd. ex Schult (MEDC) on Letrozole-Induced Polycystic Ovary Syndrome Via Modulation of Apoptotic Markers, Sex Hormones and Antioxidant Status in Rat Model. Reprod Sci 2024:10.1007/s43032-024-01597-6. [PMID: 38773025 DOI: 10.1007/s43032-024-01597-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Accepted: 05/13/2024] [Indexed: 05/23/2024]
Abstract
Polycystic ovary syndrome (PCOS) is a gynecological disorder among reproductive-aged women and a major cause of infertility. Different treatment options are being employed but with side effects. This has mandated alternative treatment options, especially complementary therapy. This study therefore investigated the possible protective effects of methanol extract of Drymaria cordata in Letrozole-induced PCOS. The plant is folklorically used in the treatment of diverse ailments including PCOS, fibroids, uterine/ovarian/breast tumors, and cancers. Forty-eight female Wistar rats were acclimatized and initially divided into two groups: group I(control group) and group II(PCOS group). PCOS was induced by the oral administration of letrozole/high-fat diet for 21 days. After the induction, the PCOS group was sub-divided into four groups (n = 4): group II (positive control with PCOS), group III (MET 2mg/kg), group IV (MEDC 200mg/kg), and group V (MEDC 400mg/kg). Rats were orally treated with MET and MEDC for six weeks after the PCOS induction. At the end of the experimental period, blood samples were collected, sera were separated, mitochondria were isolated, and the mPT, some apoptotic biomarkers, hormonal and lipid profiles, and oxidative stress markers were determined. Ovarian histological evaluation and GC-MS analysis of MEDC were carried out. There was no significant mPT pore opening in the PCOS (untreated) group. However, treatments with MEDC caused significant mPT pore opening, upraised caspase 9, caspase 3, and Bax, and decreased anti-apoptotic Bcl-2 levels. The MEDC treatments restored the hormonal and lipid profiles, increased the levels of GSH-Px and SOD and decreased TBARS. Histological examination revealed resolved ovarian cysts and improved follicular growth with MEDC treatments. Comparable results were observed for both MEDC and metformin. The GC-MS analysis revealed the presence of some major pharmacologically relevant compounds. These findings suggest that MEDC contains phytochemicals that can protect against letrozole-induced PCOS possibly by normalizing the impaired hormonal balance, restoring the lipid profile, and improving the antioxidant milieu of the system.

Ethnobotanical and ethnopharmacological survey of medicinal tree species used in the treatment of diseases by forest-fringe communities of Southwestern Ghana. Heliyon 2024; 10:e23645. [PMID: 38226220 PMCID: PMC10788458 DOI: 10.1016/j.heliyon.2023.e23645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 11/24/2023] [Accepted: 12/08/2023] [Indexed: 01/17/2024] Open
Abstract
Demand for medicinal plant remedies is rising globally, while indigenous knowledge about medicinal plants is declining rapidly. The preservation of indigenous knowledge is critical in discovering and developing innovative drugs. The ongoing discussions on providing nature-based solutions to contemporary issues make it urgent to document indigenous knowledge about medicinal trees, especially in areas with limited or no studies such as our study area. Our study aimed to understand the use of medicinal trees among the communities fringing the Asukese and Amama Shelterbelt Forest Reserves. We administered structured questionnaires and interviewed 88 respondents who were selected using snowball and simple random techniques. The ethnobotanical survey data were processed and evaluated using parameters such as Indigenous Knowledge Index (IKI), Relative Citation Frequency (RCF), Species Use Value (SUV), Family Use Value (FUV), and Plant Part Value (PPV). We found that ethnobotanical knowledge about medicinal trees was higher in respondents who were widowed or had larger number of dependants. We found that the local communities used diverse medicinal trees (70 species belonging to 33 families) to treat 83 ailments. Azadirachta indica had the highest RCF (8.9) and SUV (23.4). The other top four species according to the SUV were Alstonia boonei (SUV = 11.1), Khaya senegalensis (SUV = 10.7), Moringa oleifera (SUV = 10.3) and Cocos nucifera (SUV = 10.2). The most-well represented and valuable families were Fabaceae, Anacardiaceae, Meliaceae, Arecaceae, Rubiaceae and Malvaceae. Medicinal trees had alternative uses such as food, fodder, fuelwood, and construction material. Indigenous knowledge about medicinal trees was transmitted to younger generations predominantly by parents. The results show that the most known botanical families and species with the most useful parts were the most useful plant families and species. Thus, the selection of medicinal trees was driven by their traits. Furthermore, results indicate that species diversity is critical to the healthcare needs of local communities and that their conservation and sustainable use and the preservation of indigenous knowledge are crucial to ensuring good health and the general well-being of local communities of all ages.

Leaf Extract in Mice: Survivability Depends Less on Parasitaemia Suppression. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2023; 2023:5560711. [PMID: 38161788 PMCID: PMC10757657 DOI: 10.1155/2023/5560711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 05/24/2023] [Accepted: 12/14/2023] [Indexed: 01/03/2024]
Abstract
Sida cordifolia has been used to treat malaria in Ghana albeit without scientific evidence of antimalarial activity and safety. This work aimed to assess the antimalarial properties and acute toxicity of the aqueous leaf extract of S. cordifolia in murine models. Aqueous extract of the plant was analysed for both suppressive and curative antimalarial properties in chloroquine-sensitive ANKA strains of rodent Plasmodium berghei-infected mice. Acute toxicity evaluation was performed in rats according to the OECD 425 guidelines. The extract displayed antiplasmodial activity in vivo with ED50 of 117.49 ± 15.22 mg/kg and 144.84 ± 18.17 mg/kg in suppressive and curative studies, respectively. The highest % parasitaemia suppression exerted was 76.90 ± 0.64% and 61.50 ± 0.97%, respectively, in the suppressive and curative studies. Survival of infected mice treated with the extract was significantly prolonged. This was dependent on the dose of the extract but imperfectly related to the % parasitaemia suppression. Related antimalarial parameters including percentage hematocrit, changes in body weight, and temperature of experimental mice indicated alleviation of malarial symptoms of treated animals. The extract did not show toxicity in rats. Sida cordifolia L. has antimalarial properties, and was safe. It suppressed parasitaemia in both suppressive and curative studies, was not toxic to animals and prolonged the life of infected animals under treatment. This, therefore, justifies the traditional use of S. cordifolia for the treatment of malaria in Ghana.

[DOI: 10.3390/healthcare10112327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 11/08/2022] [Accepted: 11/13/2022] [Indexed: 11/22/2022] Open
Abstract
Southern Morocco, particularly the Guelmim-Oued Noun region, is rich in a wide diversity of plant species. Pregnant women in this region use medicinal plants during pregnancy and childbirth for various purposes; however, the use of these plants has never been documented. The objectives of this study are threefold: to estimate the prevalence of medicinal plant uses by pregnant women in the province of Guelmim, Morocco, to describe the traditional practices of self-medication and to determine the associated factors. This is a multicenter cross-sectional study with descriptive and analytical approaches. Data were collected using an interview questionnaire, which was administered to pregnant women at health care centers and hospitals in the province of Guelmim. A total of 560 women participated in this study. The prevalence of medicinal plant use was 66.96%. Artemisia herba-alba Asso, Thymus maroccanus Ball., Trigonella foenum-graecum L., Aloysia citriodora Palau, Lepidium sativum L. and Cuminum cyminum L. were the plants with the highest UV. Pain, the induction and facilitation of childbirth, flu syndrome and anemia were the most listed reasons for use. The use of medicinal plants was significantly associated with the level of education (chi-square = 15.651; p = 0.004), and pregnancy monitoring (chi-square = 5.283; p = 0.028). In the province of Guelmim, the prevalence of the use of medicinal plants by women during pregnancy and childbirth is high. Further research is necessary in order to explore potential associated risks and complications.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 295:115327. [PMID: 35504505 DOI: 10.1016/j.jep.2022.115327] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 04/18/2022] [Accepted: 04/23/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The plants are from the genus Rauvolfia Plum. ex L. (Apocynaceae), which is represented by 74 species with many synonyms, and distributed worldwide, especially in the Asian, and African continents. Traditionally, some of them are used for the treatment of various disorders related to the central nervous system (CNS), cardiovascular diseases (CVD), and as an antidote due to the presence of monoterpene indole alkaloids (MIAs) such as ajmaline (144), ajmalicine (164) serpentine (182), yohimbine (190) and reserpine (214). AIM The present review provides comprehensive summarization and critical analysis of the traditional to modern applications of Rauvolfia species, and the major focus was to include traditional uses, phytochemistry, quality control, pharmacological properties, as well as clinical evidence that may be useful in the drug discovery process. MATERIALS AND METHODS Information related to traditional uses, chemical constituents, separation techniques/analytical methods, and pharmacological properties of the genus Rauvolfia were obtained using electronic databases such as Web of Science, Scopus, SciFinder, PubMed, PubChem, ChemSpider, and Google Scholar between the years 1949-2021. The scientific name of the species and its synonyms were checked with the information of The Plant List. RESULTS A total of seventeen Rauvolfia species have been traditionally explored for various therapeutic applications, out of which the roots of R. serpentina and R. vomitoria are used most commonly for the treatment of many diseases. About 287 alkaloids, seven terpenoids, nine flavonoids, and four phenolic acids have been reported in different parts of the forty-three species. Quality control (QC)/quality assurance (QA) of extracts/herbal formulations of Rauvolfia species was analyzed by qualitative and quantitative methods based on the major MIAs such as compounds 144, 164, 182, 190, and 214 using HPTLC, HPLC, and HPLC-MS. The various extracts of different plant parts of thirteen Rauvolfia species are explored for their pharmacological properties such as antimicrobial, antioxidant, antiprotozoal, antitrypanosomal, antipsychotic, cardioprotective, cholinesterase inhibitory, and hepatoprotective. Of which, clinical trials of herbal formulations/extracts of R. serpentina and MIAs have been reported for CVD, CNS, antihypertensive therapy, antidiabetic effects, and psoriasis therapy, while the extracts and phytoconstituents of remaining Rauvolfia species are predominantly significant, owning them to be additional attention for further investigation under clinical trials and QC/QA. CONCLUSION The present communication has provided a comprehensive, systematic, and critically analyzed vision into the traditional uses, phytochemistry, and modern therapeutic applications of the genus Rauvolfia are validated by scientific evidence. In addition, different plant parts from this genus, especially raw and finished herbal products of the roots of R. serpentina have been demonstrated for the QC/QA.

Matos P, Batista MT, Figueirinha A. A review of the ethnomedicinal uses, chemistry, and pharmacological properties of the genus Acanthus (Acanthaceae). JOURNAL OF ETHNOPHARMACOLOGY 2022; 293:115271. [PMID: 35430290 DOI: 10.1016/j.jep.2022.115271] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/26/2021] [Revised: 03/25/2022] [Accepted: 04/05/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Acanthus genus belongs to the Acanthaceae family, and its species are distributed in all continents, mainly in tropical and subtropical regions. Several traditional applications are referred to, but few scientific studies validate them. Despite this, studies in animal models corroborate some of its uses in folk medicine, such as anticancer, antidiabetic, anti-inflammatory, and antinociceptive, which encourages the research on plants of this genus. AIM OF THE REVIEW To our knowledge, this document is the first comprehensive review study that provides information on the geographic distribution, botanical characteristics, ethnomedicinal uses, phytochemicals, and pharmacological activities of some Acanthus species to understand the correlation between traditional uses, phytochemical, and pharmacological activities, providing perspectives for future studies. RESULTS In traditional medicine, Acanthus species are mainly used for diseases of respiratory, nervous and reproductive system, gastrointestinal and urinary tract, and skin illness. The most used species are A. montanus, A. ilicifolius, and A. ebracteatus. Chemical compounds (125) from different chemical classes were isolated and identified in seven species, mainly from A. ilicifolius, about 80, followed by A. ebracteatus and A. montanus, appearing with a slightly lower number with fewer phytochemical profile studies. Isolated phytoconstituents have been mainly alkaloids, phenylpropanoid glycosides, and phenylethanoids. In addition, aliphatic glycosides, flavonoids, lignan glycosides, megastigmane derivatives, triterpenoids, steroids, fatty acids, alcohols, hydroxybenzoic acids, simple phenols were also cited. Scientific studies from Acanthus species extracts and their phytoconstituents support their ethnomedical uses. Antimicrobial activity that is the most studied, followed by the antioxidant, anti-inflammatory, and anticancer properties, underlie many Acanthus species activities. A. dioscoridis, A. ebracteatus, A. hirsutus, A. ilicifolius, A. mollis, A. montanus, and A. polystachyus have studies on these activities, A. ilicifolius being the one with the most publications. Most studies were essentially performed in vitro. However, the anticancer, antidiabetic, anti-inflammatory and antinociceptive properties have been studied in vivo. CONCLUSION Acanthus species have remarkable phytoconstituents with different biological activities, such as antioxidant, antimicrobial, anti-inflammatory, antinociceptive, hepatoprotective, and leishmanicidal, supporting traditional uses of some species. However, many others remain unexplored. Future studies should focus on these species, especially pharmacological properties, toxicity, and action mechanisms. This review provides a comprehensive report on Acanthus genus plants, evidencing their therapeutic potential and prospects for discovering new safe and effective drugs from Acanthus species.

Islam ATMR, Hasan MM, Islam MT, Tanaka N. Ethnobotanical study of plants used by the Munda ethnic group living around the Sundarbans, the world's largest mangrove forest in southwestern Bangladesh. JOURNAL OF ETHNOPHARMACOLOGY 2022; 285:114853. [PMID: 34822959 DOI: 10.1016/j.jep.2021.114853] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 11/17/2021] [Accepted: 11/17/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Indigenous knowledge of medicinal plants is an integral part of the primary health care (PHC) system in almost every society. For more than two centuries, Munda, a small ethnic group in Bangladesh, has lived around the Sundarbans, the world's largest mangrove forest. This mangrove is rich in biodiversity but is threatened by global climate change. Information on the therapeutic use of plants by Munda ethnic minorities remains completely unknown. Therefore, it needs urgent documentation. AIM OF THE STUDY The purpose of the study is (1) to search and compile data on the diversity of medicinal plants used by the Munda people for PHC needs, and (2) Quantitative analysis of these data to identify important medicinal plants and diseases related to treatment by this species. MATERIAL AND METHODS We conducted repeated field surveys and interviews among 79 Munda informants to collect ethnobotanical data. Informants were selected through random sampling techniques and interviewed using an open and semi-structured questionnaire. We reported the primary (absolute) data as use reports (URs) with frequency citation (FC). The International Classification of Primary Care-2 (ICPC-2) was followed to categorize the therapeutic use of medicinal plants, and quantitative analysis was performed using the FC and informant consensus factor (ICF). RESULTS The present study explored and compiled a total of 3199 medicinal URs for 98 medicinal plant species to treat 132 ailment conditions under sixteen (16) ICPC-2 pathological groups. The highest URs (948) were noted for the digestive (D) group treated by 69 plant species, where the highest ICF value was measured for the social problem (Z) disease category (ICF: 1.00). Of the recorded medicinal plants, 17 were identified as true Mangrove (MNG), 24 as Mangrove Associates (MNA), and 57 as Non-Mangrove (NMG) species. Fabaceae (13 species) represented the leading family, followed by Lamiaceae and Compositae (5 species). Herbs (43%) have shown dominant life forms, and the leaves (41%) were frequently used plant parts. The most commonly cited preparation method was juice (24%), and the prevalent mode of administration was oral (62%). Azadirachta indica A. Juss. was the most widely used therapeutic plant species based on FC (39) values. The comparative literature review study reveals that the practices of 15 plants and their ethnomedicinal use by the Munda people are still entirely unexplored and newly reported in Bangladesh. Additionally, therapeutic use of 2 species, Brownlowia tersa (L.) Kosterm., and Dalbergia candenatensis (Dennst.) Prain has not been previously reported worldwide. In addition, 51 plant species (52%) of the total plants studied enlisted on the IUCN Red List of Threatened Species. CONCLUSION To our knowledge, this is the first ethnobotanical study on the Munda ethnic group in Bangladesh. This study indicates that Munda people still rely on medicinal plants for PHC and have a rich and varied traditional knowledge about the therapeutic use of plants. This study also warns of the high risk of the current availability status of plants in the study area. Therefore, this study calls for urgent steps to protect and conserve high-risk plants that can be done by taking both in-situ and ex-situ measures. In addition, further phytochemical and pharmacological investigations of the important medicinal plants cited in the study have been suggested.

Huang SS, Huang CH, Ko CY, Chen TY, Cheng YC, Chao J. An Ethnobotanical Study of Medicinal Plants in Kinmen. Front Pharmacol 2022; 12:681190. [PMID: 35222004 PMCID: PMC8864234 DOI: 10.3389/fphar.2021.681190] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Accepted: 12/08/2021] [Indexed: 01/04/2023] Open
Abstract
Kinmen is an outlying island that has the richest plant resources in Taiwan. The objective of this study was to record the methods that people in Kinmen use medicinal plants and to analyze the cultural characteristics of their use. Field investigations were carried out in various towns and villages in Kinmen, and 80 respondents were included in the survey. The search for respondents was conducted through local elderly people and medicinal plant groups. Semi-structured interviews were conducted with the local people to obtain their knowledge of medicinal plants and how they disseminate this information. Informed consent was obtained prior to the interviews, and the following was determined: plant use value (UV), frequency of citation (FC), and factor of informant consensus (Fic). These parameters were used to quantify the data and measure the agreement among the respondents on using plants to treat different diseases. Finally, the survey results were compared with the representative ethnobotanical literature in neighboring areas to evaluate the similarity between plant usage in Kinmen and neighboring areas as well as to determine whether there are new species or novel usages in the study area. In the Kinmen area, phytotherapy is generally used by elderly people with low educational attainments. According to the survey results, 83 medicinal plants belonging to 48 families were collected. These medicinal plants were mainly distributed in the Compositae, Lamiaceae, and Solanaceae families. Eighteen novel uses that have not been previously documented were found, four of which were related to newly recorded medicinal plant species in the Kinmen area. The results showed that 93.98 and 65.06% of the species collected in the present study were also recorded in literature from Taiwan and Fujian, respectively. This study showed that Kinmen’s ethnobotanical knowledge is closely related to the Catalogue of Medicinal Plant Resources in Taiwan, and local people indeed shared similar uses of medicinal species with people in Taiwan and Fujian (46.99%). The results from this study highlighted the importance of traditional medicine in the Kinmen area, where people have a specific understanding of using medicinal plants and communication with people in Taiwan and Fujian Province in China. It was found that Kinmen shares ethnobotanical knowledge with Taiwan and Fujian.

Potential benefits versus hazards of herbal therapy during pregnancy; a systematic review of available literature. Phytother Res 2022; 36:824-841. [PMID: 35023227 DOI: 10.1002/ptr.7363] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Revised: 11/03/2021] [Accepted: 12/10/2021] [Indexed: 11/07/2022]
Abstract
The use of herbal medicine has considerably grown worldwide in the past two decades. Studies have shown that the prevalence of herbal diet therapy in pregnancy ranged from 1% to 60% in different societies. Many clinical reports have shown that some herbal medicines may have toxic effects on pregnant women and their fetuses because active ingredients of some medicinal plants can readily pass through the biological barriers (e.g., placental barrier). In the present study, we aimed to systematically review the literature to discover potential benefits versus the hazards of herbal therapy during pregnancy. For this purpose, a comprehensive literature review was performed, and after the literature search and selection of the appropriate documents, the desired data were extracted and reported. From 35 articles with a total of 39,950 study population, the results showed that some medicinal plants could cause severe toxicity on mothers and fetuses, in addition to abortion during pregnancy. It was also shown that some plants may lead to developmental abnormalities or fetal death. Findings of this survey showed that some herbal medicines have toxic, teratogenic, and abortive potential, particularly in the first trimester of pregnancy because active ingredients of some medicinal plants are able to pass through the placental barrier and reach the fetus.

Ethnotherapeutic Uses and Phytochemical Composition of Physalis peruviana L.: An Overview. ScientificWorldJournal 2021; 2021:5212348. [PMID: 34671227 PMCID: PMC8523295 DOI: 10.1155/2021/5212348] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Revised: 09/11/2021] [Accepted: 09/24/2021] [Indexed: 11/17/2022] Open
Abstract
Background Plant-derived medicines are widespread and continue to increase in traditional and modern medicine, especially in developing countries. Physalis peruviana L. is among the most used plants in conventional medication worldwide. This review aimed to highlight the ethnotherapeutic uses and phytochemical status of identified compounds in P. peruviana. Methods Data were collected from Google Scholar, PubMed/Medline, SciFinder, Science Direct, Scopus, the Wiley Online Library, Web of Science, and any other helpful search engine using Physalis peruviana as the primary keyword. Results Some countries, worldwide, use P. peruviana in their traditional medicine system to manage diverse ailments, mainly diseases and gastrointestinal tract disorders (25.33%). Leaf was the mostly used part (49.28%), prepared by decoction (31.58%) and overall administrated orally (53.57%) as the main route of admission. Around 502 phytoconstituents were identified in different plant parts, especially fruit (38.19%) ethanol/ethyl acetate extract. In most cases (36.17%), the solvent of the extract was not specified. Several phytochemical classes were found in the plant, especially terpenes (26.09%) and phenolic compounds (14.94%). Esters were also abundant (11.55%). In the terpenes category, carotenoids were the most abundant (11.15% followed by monoterpenes (8.76%) and diterpenes (3.18%). However, flavonoids (5.17%) followed by cinnamic acid derivatives (3.99%), monophenolic compounds (1.79%), and phenolic acids (1.33 M) are the most reported phenolic compounds. Hexadecanoic acid (palmitic acid) was the most cited (five times). Conclusion P. peruviana plays an essential role in managing diseases in some countries and is rich in chemical compounds, which need to be isolated and investigated pharmacologically before clinical trials.

Inventory of Medicinal Plants Used Traditionally to Manage Kidney Diseases in North-Eastern Morocco: Ethnobotanical Fieldwork and Pharmacological Evidence. PLANTS (BASEL, SWITZERLAND) 2021; 10:1966. [PMID: 34579498 PMCID: PMC8468912 DOI: 10.3390/plants10091966] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 09/15/2021] [Accepted: 09/15/2021] [Indexed: 12/22/2022]
Abstract
Kidney disease is one of the most common health problems and kidney failure can be fatal. It is one of the health disorders associated with extreme pain and discomfort in patients. In developing countries, such as Morocco where socioeconomic and sanitary conditions are precarious, medicinal plants are considered the primary source of medication. In the present work an ethnobotanical survey was conducted in a remote area of North-Eastern Morocco and we focused on (1) establishing a record of medicinal plants used traditionally by local people to treat kidney diseases and (2) correlate the obtained ethnomedical use with well-studied pharmacological evidence. From February 2018 to January2020, information was gathered from 488 informants using semi-structured questionnaires. The data were analyzed using three quantitative indices: The use value (UV), family use value (FUV), and informant consensus factor (ICF). A total of 121 plant species belonging to 57 botanical families were identified to treat kidney diseases. The families most represented were Asteraceae (14 species), followed by Lamiaceae (12 species) and Apiaceae (10 species). The most commonly used plant parts were leaves, followed by the whole plant and they were most commonly prepared by decoction and infusion. The highest value of the (UV) index was attributed to Herniaria hirsuta L. (UV = 0.16), and the highest family use value (FUV) was assigned to Caryophyllaceae with (FUV = 0.163). Regarding the informant consensus factor (ICF), this index's highest values were recorded for kidney stones (ICF = 0.72). The use of 45% of the selected plants were validated based on literature review. This study helped document and preserve crucial traditional plant knowledge of 121 plant species used to treat kidney problems that can be used in the search for new biologically active compounds through more upcoming pharmacological studies.

Abstract
Background: Water represents the core of food-energy nexus and is vital for human survival. In developing countries, contaminated water and lack of basic water services undermine efforts to improve nutritional status and related health issues. In the rural areas of Central Africa, a majority of the population lacks access to improved water sources and has to devote considerable efforts to obtain water. Objectives: Using the following definition of water insecurity, i.e. it exists when access to adequate amount of safe and clean water does not occur all the times for the entirety of household members to lead a healthy and active life, the study aimed to develop and test a household-level experiential water insecurity scale for rural households in Central Africa. Methods: The research was conducted in three phases: 1) the formative data collection; 2) the scale development; and, 3) the scale testing. In the third Phase, the scale was tested with 250 women who were water managing person of their households. Statistical analysis included items reduction, reliability, as well as criterion and construct validity assessment. The testing led to a final scale of 17 statements (WATINE-17), covering three domains of water insecurity: 1) psychosocial distress; 2) quantity; 3) quality of water. Results: The scale showed an excellent reliability (Cronbach’s alpha = 0.92) and was significantly associated with lower frequency of water intake among women (p = 0.007, concurrent validity). In assessing WATINE-17’s predictive validity, it was found that water insecurity was positively related to food insecurity (p < 0.001) and the level of water insecurity was the highest among severely food insecure households [F (3, 246) = 22.469, p < 0.001]. Conclusion: The WATINE-17 is able to capture key elements of water insecurity and can be used to monitor and evaluate SDG# 6 and water-related programs, such as WASH, in Central Africa.

Abstract
Women act as gatekeepers in securing water for their households. Using this qualitative methodology, 35 participants were interviewed with the objectives to determine roles and responsibilities of different family members in fetching and managing water and examine differences in perceptions related to water access/use between men and women in households from rural areas of the Menoua Division, West Cameroon. We found that the household structure was key component in each family member's degree of involvement in water fetching and management. A significant gender gap was found among adults with fewer men than women experiencing coping strategies-related to water scarcity. Hence, women participation in designing water and food security initiatives is warranted.

Abstract
The crisis of antibiotic resistance necessitates creative and innovative approaches, from chemical identification and analysis to the assessment of bioactivity. Plant natural products (NPs) represent a promising source of antibacterial lead compounds that could help fill the drug discovery pipeline in response to the growing antibiotic resistance crisis. The major strength of plant NPs lies in their rich and unique chemodiversity, their worldwide distribution and ease of access, their various antibacterial modes of action, and the proven clinical effectiveness of plant extracts from which they are isolated. While many studies have tried to summarize NPs with antibacterial activities, a comprehensive review with rigorous selection criteria has never been performed. In this work, the literature from 2012 to 2019 was systematically reviewed to highlight plant-derived compounds with antibacterial activity by focusing on their growth inhibitory activity. A total of 459 compounds are included in this Review, of which 50.8% are phenolic derivatives, 26.6% are terpenoids, 5.7% are alkaloids, and 17% are classified as other metabolites. A selection of 183 compounds is further discussed regarding their antibacterial activity, biosynthesis, structure-activity relationship, mechanism of action, and potential as antibiotics. Emerging trends in the field of antibacterial drug discovery from plants are also discussed. This Review brings to the forefront key findings on the antibacterial potential of plant NPs for consideration in future antibiotic discovery and development efforts.

Tomani JCD, Kagisha V, Tchinda AT, Jansen O, Ledoux A, Vanhamme L, Frederich M, Muganga R, Souopgui J. The Inhibition of NLRP3 Inflammasome and IL-6 Production by Hibiscus noldeae Baker f. Derived Constituents Provides a Link to Its Anti-Inflammatory Therapeutic Potentials. Molecules 2020; 25:molecules25204693. [PMID: 33066442 PMCID: PMC7587372 DOI: 10.3390/molecules25204693] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2020] [Revised: 10/12/2020] [Accepted: 10/12/2020] [Indexed: 12/15/2022] Open
Abstract
The activation of NOD-, LRR-, and pyrin domain-containing protein 3 (NLRP3) inflammasome and/or its components is associated with the physio-pathogenesis of many respiratory diseases including asthma, COPD (chronic obstructive pulmonary disease), SARS Cov-2 (severe acute respiratory syndrome coronavirus 2), and in several autoimmune diseases. Hibiscus noldeae Baker f. has been widely reported to be traditionally used in the treatment of different ailments, some of which are of inflammatory background such as asthma, wounds, headache, etc. However, the claims have not been supported by evidence at the molecular and functional levels. Here, we report on the bio-guided fractionation of H. noldeae and assessment of the inhibitory properties of some fractions and purified compounds on NLRP3 inflammasome and Interleukin 6 (IL-6). The activation of the NLRP3 inflammasome was determined by detecting the activity of caspase-1 and the production of Interleukin 1β (IL-1β) in Lipopolysaccharide (LPS) and ATP-stimulated Tamm-Horsfall Protein 1 (THP-1) macrophages, while the production of IL-6 was studied in LPS-stimulated RAW264.7 mouse macrophages. It was observed that hexane and ethyl acetate fractions of the crude extract of the aerial parts of H. noldeae, as well as caffeic acid, isoquercetin, and ER2.4 and ER2.7 fractions revealed significant inhibitory effects on Caspase-1 activities, and on IL-1β and IL-6 production. The ER2.4 and ER2.7 fractions downregulated the production of IL-1β and IL-6, in a similar range as the caspase-1 inhibitor AC-YVAD-CHO and the drug Dexamethasone, both used as controls, respectively. Overall, our work does provide the very first scientific based evidence for Hibiscus noldeae anti-inflammatory effects and widespread use by traditional healers in Rwanda for a variety of ailments.

Nounkeu CD, Dharod JM. A Qualitative Examination of Water Access and Related Coping Behaviors to Understand Its Link to Food Insecurity among Rural Households in the West Region in Cameroon. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E4848. [PMID: 32640517 PMCID: PMC7369772 DOI: 10.3390/ijerph17134848] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 06/27/2020] [Accepted: 06/30/2020] [Indexed: 11/25/2022]
Abstract
Food insecurity is a significant public health issue, since it causes malnutrition and engenders millions of deaths every year. A significant association is found between water and food insecurity. However, it remains unclear what are the pathways through which water shortage impacts food insecurity. Hence, a qualitative study was conducted in rural areas in Cameroon to (1) examine water access, its management, and its daily use and (2) investigate common behavior changes and coping strategies adults used in managing limited water availability in their households. Three rounds of focus group discussions and six key informant interviews were conducted with men and women. The results demonstrated that water access was limited, involving long walking distances and making several trips to the water sources. The household size, number of adults vs. children, and presence of storage containers affected water availability and its daily use. To manage limited water, coping behaviors included skipping drinking, changing cooking plans, and recycling water. In conclusion, limited water access increases food insecurity through several pathways. Governments, policy makers, and international organizations should recognize the interwoven link between water and food security. Joint actions and collaborative efforts are needed to improve success and reduce tradeoffs in achieving Sustainable Development Goals # 2 and # 6.

Abstract
Millions of people suffer from Musculoskeletal System Disorders (MSDs), including Karen people who work hard in the fields for their subsistence and have done so for generations. This has forced the Karen to use many medicinal plants to treat MSDs. We gathered data from 15 original references covering 27 Karen communities and we document 461 reports of the use of 175 species for treating MSDs among the Karen people in Thailand. The data were analyzed by calculating use values (UV), relative frequency of citation (RFC) and informant consensus factor (ICF). Many use reports and species were from Leguminosae and Zingiberaceae. Roots and leaves were the most used parts, while the preferred preparation methods were decoction and burning. Oral ingestion was the most common form of administration. The most common ailment was muscle pain. Sambucus javanica and Plantago major were the most important species because they had the highest and second-highest values for both UV and RFC, respectively. This study revealed that the Karen people in Thailand use various medicinal plants to treat MSDs. These are the main resources for the further development of inexpensive treatments of MSDs that would benefit not only the Karen, but all people who suffer from MSD.

Abstract
Herbal tea, a beverage prepared from a variety of plant materials excluding the leaves of the tea plant Camellia sinensis (L.) Kuntze of the family Theaceae, for a long time, has been consumed by most Chinese people for preventive and/or therapeutic health care. Usually, it is brewed or prepared as a decoction of local plants in water. The qīng-căo-chá tea, a commercial herbal tea, is the most common among many differently formulated herbal teas in Taiwan. For hundreds of years, qīng-căo-chá tea has played an important role in the prevention and treatment of diseases associated with the environmental conditions in Taiwan. However, research studies in this field have been insufficient. The raw material formulas of qīng-căo-chá tea have always been passed down from “masters” to “apprentices.” Hence, there is no systematic collation or record, and, therefore, there is a need to assess and confirm the composition, safety, and effectiveness of the raw materials. This study aimed to document the uses of Taiwan's qīng-căo-chá tea through a semi-structured interview survey and investigate the background of traditional practitioners, tea compositions, and plant origins and uses. This will improve our understanding of the knowledge inherited by the practitioners and the theoretical basis of the medicinal uses of these teas. In our field investigation, we visited 86 shops and assessed 71 raw ingredients of qīng-căo-chá tea. A semi-structured questionnaire was used to conduct the interviews. During the interviews, in addition to written records, audio and video recordings were made, and photographs were taken with the permission of the interviewees. The qīng-căo-chá raw materials have long been used as herbal teas, although more research should clarify their efficacy and safety. Traditional sellers of qīng-căo-chá tea were mainly males, and most shops have been in operation for more than 71 years. Some of the raw materials were derived from multiple sources, including different plants, and were often mixed without any safety concerns. To our knowledge, this is the first systematic ethnobotanical study on qīng-căo-chá tea that assesses and confirms its herbal ingredients. Our study represents a reference for herbal teas in Taiwan that can be used by the public and regulatory agencies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Coccinia barteri (Hook. F.) is traditional used in Southeast of Nigeria in management of fever. This study aimed to evaluate the antimalarial activities of hydro-methanol crude extract and solvent fractions of Coccinia barteri leaf. MATERIALS AND METHODS Two animal models employed for the study were, 4-day suppressive and curative assays against chloroquine sensitive Plasmodium berghei NK65. Level of parasitaemia, mean survival time (MST), anal temperature and weight loss were measured to assess antimalarial efficacy of the extract/fractions. Chloroquine (10 mg kg-1) was used as positive control. Chemo-profile of extract was evaluated using GC-MS, HPLC techniques and standard phytochemical analysis. Preliminary toxicity test was done using modified Lorke's method. RESULTS The crude extract (100-400 mg kg-1) and solvent fractions (20-80 mg kg-1) demonstrated antimalarial activity in both models compared to controls. Semi purified fractions of the extract produced stronger percentage chemosuppression and inhibition of parasite. The % inhibition of the fractions, hexane, chloroform, ethyl acetate and aqueous at 80 mg kg-1 were 96.0 0, 95.29, 89.86 and 96.00% respectively on day 8 (D8). While on D14, 100% parasite clearance, indicating cure was obtained for hexane, chloroform and aqueous fraction treatment groups, no death occurred in these groups. Ethyl acetate fraction treated groups lived longer but were not fully protected. Some marker compounds were identified. CONCLUSIONS These results support the use of C. barteri as malaria remedy and potential source of antimalarial templates. Long acting parasitaemia reduction effect indicates its possible combination potential in poly-herbal combination therapy.

Abstract
BACKGROUND Being an isolated locality and having a tough mountainous terrain, strong ethnomedicinal practices still prevail in Dhirkot and its allied areas, which have been rarely explored yet. The present study was intended with the aim to document and compare the traditional knowledge of local communities on botanical taxa of Dhirkot, Azad Jammu, and Kashmir. METHODOLOGY Ethnomedicinal data were collected from 74 informants using a semi-structured questionnaire in addition to field observation and group discussion. Various indices were also used to evaluate the ethnomedicinal data. Furthermore, the present findings were compared with previous reports to assess data novelty. RESULT A total of 140 medicinal plant species belonging to 55 families were recorded, which are used by local communities to treat 12 disease categories. Asteraceae was dominating with 20 species, followed by Poaceae, Lamiaceae, and Rosaceae (14, 11, and 10 species, respectively). Herbs were leading with 66% contribution, whereas leaves were the most utilized plant part with 29% utilization and decoction was the common mode of administration. Viola canescens depicted the highest use value and relative frequency of citation (1.7 and 0.92, respectively). Maximum informant consensus factor (0.88) was calculated for digestive and liver disorders. Five plant species including Berberis lycium Mentha arvensis Pyrus malus, Taraxacum officinale, and Viola canescens had 100% fidelity level. CONCLUSION Dhirkot and its allied areas harbor rich botanical and cultural diversity because of its unique geography and diverse climatic conditions. However, mostly, traditional ethnobotanical knowledge is restricted to healers, midwives, and older people, and could be extinct in the near future. Therefore, such documentation not only conserves traditional knowledge but may also contribute significantly to novel drug resources.

Abstract
Abstract
Objective. Polycystic ovary syndrome (PCOS) is a common and multifactorial disease associated with female factor infertility. Ulmus minor bark (UMB) is one of the medicinal plants used in Persian folklore as a fertility enhancer. In the current study, we aimed to elucidate the effect of UMB hydro-alcoholic extract on histological parameters and testosterone condition in an experimental model of PCOS rats.
Methods. Thirty female rats were randomly divided into five groups: (1) control, (2) vehicle, (3) PCOS/50 mg [6 mg/kg dehydroepiandrosterone (DHEA) + 50 mg/kg UMB hydro-alcoholic extract], (4) PCOS/150 mg (6 mg/kg DHEA + 150 mg/kg UMB hydro-alcoholic extract), and (5) PCOS (6 mg/kg DHEA). All interventions were performed for 21 days. Afterwards, stereological analysis was done for determination of ovarian volume and follicle number. The serum level of testosterone was measured by ELISA kit.
Results. UMB hydro-alcoholic extract improved the total number of the corpus luteum in the treatment groups when compared to the PCOS group (p<0.05). PCOS/150 mg and PCOS/50 mg groups showed significantly lower total number of the primordial, primary, and secondary follicles as well as testosterone level compared to the PCOS group (p<0.05). The total number of antral follicles and volume of ovary did not differ significantly between groups.
Conclusion. UMB extract may be an effective and good alternative in improving PCOS histo-logical and testosterone disturbances although further studies are warranted to confirm the safety of UMB plant in human.

Abstract
People living with HIV (PLHIV) in Cameroon often seek care from traditional health practitioners (THPs) and use medicinal plants (MP). Most MP, however, still lacks evidence for their efficacy and safety, and their use, often undisclosed to referring physicians, may interfere with standard therapies. Therefore, we conducted a survey of 247 PLHIV in Dschang to assess the determinants, prevalence and trend of MP use. Besides, we surveyed 16 THPs about the use of MP in PLHIV and HIV-related knowledge. 54.9% PLHIV declared using in total 70 plants, 91.3% users were satisfied with MP, and unwanted effects were reported in 2 cases. MP users were less educated than nonusers, had longer disease duration and were more often unemployed. Only 3 THPs used MP in PLHIV, and most of them had insufficient knowledge of HIV. Results may be useful for education on HIV and integration of traditional medicines with conventional therapeutics.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Homegardens are important habitats for medicinal plants and traditional knowledge, especially among indigenous groups in remote areas. In homegardens, medicinal plants and traditional knowledge are well conserved through human management and ease of access. AIM OF THE STUDY To understand the drivers of diversity and the composition of homegardens with focus on medicinal plants, including exotic species, and their uses. We compare the homegardens of four ethnic groups in northern Thailand (Thai Yuan, Lahu, Karen, and Lisu). METHODS We inventoried all medicinal species in 195 homegardens from four villages belonging to the four ethnic groups. The owners were asked to point out all useful species in their homegardens. For any medicinal species, they were then interviewed about their main and secondary uses, medicinal properties, plant part used, preparation methods, and route of administrations. RESULTS We recorded 95 medicinal homegarden plant species ranging from 20-59 species per village and ethnic group. Most of the medicinal plants had a primary use as food plants, which demonstrated the close relationship between local food and medicine in the lives of these ethnic groups. Many of the medicinal plants were also used as food additives, ornamentals, or materials, showing that medicinal plants are not an exclusive category in the homegardens. The number of homegarden plants varied almost four-fold from 58 species in one village to 211 in the most species rich village. The number of medicinal homegarden plants varied accordingly from 20 to 59 in the poorest and the richest villages. Five medicinal species were found in all villages, but 70% of the medicinal plants were found in only one village. Infection & infestation, Nutritional disorders, and Digestive system disorders were the three most important medicinal use categories for plants in the homegardens, and all three categories were found in most of the studied homegardens. Of the 95 species with medicinal uses, 26 (27%) were exotic, which shows that local people amplify the spectrum of alternative ways to treat their illnesses. CONCLUSION Homegardens are an important source of ethnomedicinal species and knowledge. These species are beneficial for treating acute and common ailments; they are easy to access and can be prepared by simple methods, which are suitable for treating disorders, such as infections or any digestive system ailments. Medicinal plants in homegardens have been important in improving health, at least, at the family level.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Respiratory diseases and asthma, in particular, are nowadays a global health problem. In Rwanda, some traditional healers claim to treat asthma with plant-based recipes, though there is no scientific proof so far. AIM OF THE STUDY Our study aimed at evaluating the toxicity and the anti-inflammatory effect of plant recipes used in Rwanda against asthma in order to select potential candidates for further characterization of the active compounds. MATERIALS AND METHODS Water (aqueous) and methanol-dichloromethane (organic) extracts from selected folkloric recipes were submitted for toxicity test on THP-1 derived macrophages using CellTiter-Glo Luminescent Cell Viability Assay. The evaluation of the anti-inflammatory effect of the plant extracts was carried out using the Caspase-Glo 1 Inflammasome assay on THP-1 -derived macrophages. RESULTS Most of both organic and aqueous extract showed more than 95% of cell viability up to 200 µg/ml, except for R03Cn organic extract that inhibited 25% of the cell viability. Plant extracts inhibited caspase-1 activation in THP-1 derived macrophages in a dose-dependent manner. Four extracts (R03Cn and R07Kn aqueous extracts, R10MK and R19Sz organic extracts) strongly downregulated the activation of caspase-1 (more than 70% at 50 µg/ml). In general, organic extracts exhibited better caspase-1 inhibitory effects than their aqueous counterparts. CONCLUSIONS The inhibition of inflammasome/caspase-1 is one of key mechanisms of action in asthma. Some traditional recipes are active on this mechanism and are thus strong candidates for the treatment of asthma and other inflammasome-mediated diseases. Further investigations are needed to characterize active molecules.

[PMID: 30120054 PMCID: PMC6470307 DOI: 10.1016/j.jaim.2017.07.013] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2017] [Revised: 06/22/2017] [Accepted: 07/03/2017] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Ethnobotanical studies are recognized as effective methods of finding locally important plants for discovery of crude drugs. Siddha medicinal system is prevailed in south Indian states principally in Tamil Nadu and gaining recognition as alternative medicine among the indigenous communities for their primary healthcare needs. OBJECTIVES The study was aimed to explore and document folk medicinal plant knowledge among the local people in Puliyankudi village of Thiruvarur District, Tamil Nadu, India. MATERIALS AND METHODS An ethnobotanical study was carried out during February 2016 to January 2017 among the local people in study area. Traditional healers, traders, local vendors and local people who are practicing herbal medicines were approached for documentation of folk medicinal uses. Acquired results were further analyzed with descriptive statistical methods such as use value (UV) and informant consensus factor (ICF). RESULTS During the survey, a total 116 plant species from 49 families and 103 genera were recorded to treat 73 types of ailments. Among the plant parts used for preparation of medicine, leaves (73 reports) are often used and predominant method of preparation of medicine is paste (56 reports). Limonia acidissima was reported by all the interviewed informants with an UV of 0.98 and kidney problems have highest ICF value of 0.91. CONCLUSION Plants with highest use values in the study indicates possible occurrence of valuable metabolites and should be investigated for associated pharmacological activities which leads to development of potential new drugs to treat various ailments.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pastoralist Maasai populations of east Africa use several different wild plants as dietary and medicinal additives in beverages (soups and teas), yet little is known about how the plants used and the rationales for use compare and contrast across different Maasai beverages, including how gender specific dietary and health concerns structure patterns of intake. AIM OF THE STUDY We investigated three Maasai beverages: almajani (tea or herbal infusion); motorí (traditional soup); and okiti (psychoactive herbal tea). In order to build knowledge about the cultural functions of these Maasai food-medicines and their incidence of use we also investigated use rationales and self-reported frequencies of use. We conclude by examining gender differences and the possible pharmacological antimicrobial activity of the most frequently used plants. MATERIALS AND METHODS Research was conducted in 2015, with a population of semi-nomadic agropastoralist Maasai residing in northern Tanzania. Data were collected using key informant interviews, plant collections, n = 32 structured surveys, and n = 40 freelist interviews followed by a literature review to determine the known antimicrobial activity of the most used plants. RESULTS We identified 20 plants that Maasai add to soup, 11 in tea, and 11 in the psychoactive tea, for a total of 24 herbal additives. Seven plant species were used in all three Maasai beverages, and these clustered with 10 common ailments. Based on self-reports, women use the beverages less frequently and in smaller amounts than men. There were also several gender differences in the plants that Maasai add to motorí and their associated use rationales. CONCLUSIONS There are several intersections concerning the plant species used and their associated rationales for use in almajani, motori, and okiti. Moving outward, Maasai beverages and their additives increasingly involve gender specific concerns. Female use of food-medicines, relative to men, is structured by concerns over pregnancy, birth, and lactation. The frequent consumption of herbal additives, many of which contain antimicrobial compounds, potentially helps modulate infections, but could have other unintentional effects as well.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plants have provided medicine to humans for thousands of years, and in most parts of the world people still use traditional plant-derived medicine. Knowledge related to traditional use provides an important alternative to unavailable or expensive western medicine in many rural communities. At the same time, ethnomedicinal discoveries are valuable for the development of modern medicine. Unfortunately, globalization and urbanization causes the disappearance of much traditional medicinal plant knowledge. AIM OF THE STUDY To review available ethnobotanical knowledge about medicinal plants in Thailand and to estimate its diversity. METHODS Information about ethnomedicinal uses of plants in Thailand was extracted from 64 scientific reports, books, and theses produced between 1990 and 2014. Plant identifications in the primary sources were updated to currently accepted names following The Plant List website and the species were assigned to family following the Angiosperm Phylogeny Website. Use Values (UV) were calculated to estimate the importance of medicinal plant species (UVs) and families (UVf). Medicinal use categories, plant parts used, preparations of the medicine, and their applications were noted for each use report. RESULTS We found 16,789 use reports for 2187 plant species in 206 families. These data came from 19 ethnic groups living in 121 villages throughout Thailand. The health conditions most commonly treated with medicinal plants were in the categories digestive system disorders, infections/infestations, nutritional disorders, muscular-skeletal system disorders, and genitourinary system disorders. Plant families with very high use values were Fabaceae, Asteraceae, Acanthaceae, Lamiaceae, and Zingiberaceae and species with very high use values were Chromolaena odorata (L.) R.M.King & H.Rob., Blumea balsamifera (L.) DC., and Cheilocostus speciosus (J.Koenig) C.D.Specht. Stems and leaves were the most used plant parts, but also other parts of the plants were used in medicinal recipes. The most common way of using the medicinal plants was as a decoction in water. CONCLUSION We found 2187 plant species that were used in traditional medicine in Thailand. Of these a few hundred had high use values, suggesting that they may produce bioactive compounds with strong physiological effects.

Tristemma hirtum and Five Other Cameroonian Edible Plants with Weak or No Antibacterial Effects Modulate the Activities of Antibiotics against Gram-Negative Multidrug-Resistant Phenotypes. ScientificWorldJournal 2018; 2018:7651482. [PMID: 29765275 PMCID: PMC5885400 DOI: 10.1155/2018/7651482] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2017] [Revised: 01/10/2018] [Accepted: 02/19/2018] [Indexed: 01/21/2023] Open
Abstract
In order to contribute to the fight against infectious diseases, the in vitro antibacterial activity and the antibiotic-potentiating effects of Tristemma hirtum and five other Cameroonian edible plants have been evaluated against Gram-negative multidrug-resistant (MDR) phenotypes. The microdilution method was used to evaluate the bacterial susceptibility of the extracts and their combination to common antibiotics. The phytochemical screening of the extracts was carried out according to standard methods. Phytochemical analysis of the extracts revealed the presence of alkaloids, triterpenes, steroids, and polyphenols, including flavonoids in most of the tested extracts. The entire tested extracts showed moderate (512 μg/mL ≤ MIC ≤ 2048 μg/mL) to weak (MIC > 2048 μg/mL) antibacterial activities against the tested bacteria. Furthermore, extracts of leaf of Tristemma hirtum and pericarps of Raphia hookeri (at their MIC/2 and MIC/4) strongly potentiated the activities of all antibiotics used in the study, especially those of chloramphenicol (CHL), ciprofloxacin (CIP), kanamycin (KAN), and tetracycline (TET) against 70% (7/10) to 100% (10/10) of the tested MDR bacteria, with the modulating factors ranging from 2 to 128. The results of this study suggest that extracts from leaves of Tristemma hirtum and pericarps of Raphia hookeri can be sources of plant-derived products with antibiotic modifying activity.

Abstract
BACKGROUND In order to document medicinal uses of plants in the northeastern of Algeria, preserve traditional heritage and highlighted the risks of excessive human exploitation on flora and biodiversity of the region, an inventory of medicinal species existed in the traditional pharmacopoeia in Skikda region (north-east of Algeria) was made. The survey was carried out during the year (2015-2016), through face to face interviews, using pre-prepared questionnaire. The form contains: sociodemorgaphic profile of each respondent (sex, age, educational level and monthly income), local name of medicinal species used, uses, used parts and methods of preparations. RESULTS A total of 90 species belonging to 42 botanical families, were listed. The analysis of the obtained results showed that the frequency of use of medicinal plants is related to the age, sex, educational level and monthly income of our respondents. It was recorded that the majority of remedies are prepared in the form of a decoctate from the leaves of the different species, in order to treat a wide range of diseases especially those of the digestive tract. CONCLUSION Local population has a rich indigenous knowledge, but is always stays not adequately documented. It should be noted that some listed species are suffering from surexploitation which can subjects to the disappearance of the most vulnerable species. It will be urgent and essential to adopt a sustainable management strategy to avoid the degradation of biodiversity of the region.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ethnobotany takes into account past uses to be projected into the present and future. Most current ethnobotanical research is focused, especially in industrialised countries, on obtaining information of plant uses from elderly people. Historical ethnobotany is less cultivated, although papers have demonstrated its interest. Particularly poor, but potentially very relevant, is the attention paid to historical herbaria as a source of data on useful plants. AIMS OF THE STUDY Bearing this in mind, we studied the herbarium of the Catalan pharmacist and naturalist Francesc Bolòs (1773-1844), which contains information on medicinal uses and folk names, with the aim of establishing a catalogue of plants and uses and tracing them through old and contemporary literature. METHODOLOGY The ca. 6000 plant specimens of this herbarium were investigated to assess those including plant uses and names. These taxa have been thoroughly revised. The data have been tabulated, their biogeographic profile, possible endemic or threatened status, or invasive behaviour have been assessed, and the content regarding medicinal uses, as well as folk names, has been studied. The medicinal terms used have been interpreted as per current days' medicine. The popular names and uses have been compared with those appearing in a certain number of works published from 11th to 20th centuries in the territories covered by the herbarium and with all the data collected in 20th and 21st centuries in an extensive database on Catalan ethnobotany. RESULTS A total of 385 plant specimens (381 taxa) have been detected bearing medicinal use and folk names information. We collected data on 1107 reports of plant medicinal properties (in Latin), 32 indications of toxicity, nine reports of food use, and 123, 302 and 318 popular plant names in Catalan, Spanish and French, respectively. The most quoted systems are digestive, skin and subcutaneous tissue (plus traumatic troubles) and genitourinary. Relatively high degrees of coincidence of plant names and uses in the herbarium and the literature comparison set have been found. Of the taxa contained in this medicinal herbarium, 294 were native to the Iberian Peninsula, and 86 were alien. Neither endemic nor threatened taxa have been detected, whereas a considerable portion of the alien taxa shows invasive behaviour at present. CONCLUSIONS Our analyses indicate a certain degree of consistency between the medicinal uses of plants recorded in this 18th and 19th century herbarium and the records found in the literature and in recent ethnobotanical datasets, accounting for the robustness of pharmaceutical ethnobotanical knowledge in the area considered. Data appearing on the specimen labels are numerous, pointing out the herbarium as a relevant source of ethnopharmacological information. Special attention should be paid to some original uses contained in the herbarium's labels for further investigation on plant properties and drug design.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Reproductive healthcare has been highlighted as a major challenge in Lesotho mainly due to the high prevalence of HIV/AIDS and sexually transmitted infections. As a result other reproductive ailments have not received much attention, particularly because healthcare facilities are already limited and many of them are inaccessible. For these reasons, medicinal plants play a major role in primary healthcare system in the country, in addition the plants are easily accessible, more affordable, and their use forms part of the cultural heritage. However, documentation of medicinal plants used for reproductive ailments is scattered, more importantly the biological and pharmacological properties, as well as toxicity of many of these plants are not yet known. AIM OF THE STUDY To document the plants used by both male and female Basotho (residing in Lesotho) for the treatment of reproductive ailments, to explore their recorded biological and pharmacological effects as well as their toxicity, and to establish if these plants are used for similar purposes in other southern African cultures. MATERIALS AND METHODS The results stem from published findings of recent interviews of traditional medicinal practitioners in the Maseru District of Lesotho, first author's own experiences and observations from the Qacha's Nek District as well as comprehensive literature survey including numerous books and unpublished data. Electronic databases such as Google, Google Scholar, PubMed, and ScienceDirect were also used to search for the chemical compounds, pharmacological activity, and toxicity of the plants. RESULTS A total of 87 plant species are reported to be used for the treatment of several reproductive problems such as infertility, complications associated with pregnancy (twelve plants are used to treat conditions such as colic, heartburn, nausea, and constipation), cleansing and/ or toning of the uterus (with a purpose either to induce pregnancy or to get rid of the placenta, for example Withania somnifera and Zantedeschia albomaculata), difficult childbirth, as well treatment of breast and cervical cancer, cysts, fibroids, and testicular tumours (e.g. Hypoxis hemerocallidea). For the toning of the uterus, it is common to use a combination of plants, e.g. Gunnera perpensa, Scabiosa columbaria, and Eriospermum ornithogaloides. CONCLUSIONS Of the 87 plants used for reproductive healthcare, the highest number (31) is used for the treatment of infertility (in both men and women). The pharmacological effects, active compounds, and toxicology of many of these plants are not yet known.

Abstract
ETHNO-PHARMACOLOGICAL RELEVANCE Constantine and Mila regions have been investigated in an ethnobotanical study for the first time. A total of 102 medicinal plants have been cited to treat human ailments. Twenty-eight new species of 31 common plants with 151 new therapeutic applications and 12 new cited species including one endemic specie Zygophyllum cornutum Coss were found as compared to other Algerian regions. In addition, to the best of our knowledge, 369 new medicinal uses of 75 known plants, were reported for the first time in the Mediterranean basin. AIM OF THE STUDY This study is aimed at contributing to safeguard world cultural heritage and document ethnomedicinal uses of plants in Algeria and the Mediterranean basin; data on the national and global uses in the world were obtained to extract new potential species for further phytochemical and clinical investigations. MATERIALS AND METHODS The survey was carried out in two cities in the northeast of Algeria: Constantine and Mila. It was based on semi-structured interviews of 79 local informants. Data were analyzed using quantitative indices, namely, informant consensus factor, fidelity level (FL), use value (UV), and relative frequency citation (RFC), to evaluate the reliability and richness of herbal knowledge in the region. RESULTS The interviewed persons used 102 plant species belonging to 90 genera and distributed among 53 families, represented mainly by Lamiaceae, Apiaceae, and Asteraceae (30%, 13%, and 10%, respectively), which were used to treat 14 ailment categories. The category of most frequent ailments (16%) was digestive disorders (diarrhea, constipation, and stomach bloating). The highest RFC was found for Origanum glandulosum Desf. With regard to the fidelity level, a higher FL was found for Tilia cordata Mill. (100%), followed by Artemisia herba alba Asso. with an FL of 95.74% and Punica granatum L. with an FL of 93.09%) to treat gastrointestinal system diseases, and Aloe sp. L. with an FL of 96.67% for skin diseases. The highest UV was found for Origanum glandulosum Desf. (2.280). Moreover, new medicinal uses were recorded for the first time in Algeria and Mediterranean regions. CONCLUSION The present study has highlighted the rich herbal knowledge about newfound medicinal plants and their new uses in the Mediterranean region, which could be useful not only in facilitating other studies such as phytochemical and pharmacological investigations and upgrading the sources of biomolecules beneficial to people but also in reopening discussion on pharmacovigilance in herbal medicine as an imperative requirement for local authorities.

[PMID: 26773843 DOI: 10.1016/j.jep.2016.01.005] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/26/2015] [Revised: 01/05/2016] [Accepted: 01/06/2016] [Indexed: 05/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In West Africa, women utilize wild plant species to maintain and enhance their health throughout the duration of pregnancy. These plants are a culturally resilient and financially accessible form of nourishment for pregnant women in the region, many of whom are malnourished, yet studies that identify both the nutritional and medicinal properties of these plants are limited. AIM OF THE STUDY The objective of this study was to analyze women's knowledge of plants consumed in pregnancy in the southern regions of Ghana and Benin from a food-medicine continuum perspective. MATERIALS AND METHODS We gathered data in two fieldwork periods in West Africa (Ghana 2010 and Benin 2011) through herbal market surveys and 56 questionnaires with women and then conducted a literature review on known properties of the plants. RESULTS Ghanaian women reported consuming wild greens such as iron-rich Nephrolepis biserrata and tree barks such as protein-rich Ricinodendron heudelotii in a soup based on the African oil palm fruit (Elaeis guineensis), a source of fatty acids. In Benin, participants frequently reported ingesting plants during pregnancy in the form of herbal teas. Commonly cited species included Securidaca longipedunculata, Dichapetalum madagascariense, and Schwenckia americana. Several of the plants demonstrated antioxidant, anti-malarial and anti-inflammatory activity in pharmacological studies, yet the majority has incomplete nutritional and pharmacological profiles. In total, informants cited 105 species that were consumed during pregnancy. Although Ghanaian and Beninese women mentioned different species and different forms of consumption, in both countries women cited "strengthening" as the most common motivation to consume wild plants during pregnancy. Strengthening is a concept that resonates within the food-medicine continuum, bridging the local diet and herbal pharmacopoeia of women's plant use during pregnancy. CONCLUSIONS Ethnobotanical studies of this nature highlight the multidimensional use of plants and can improve health and nutritional programs in the region.

Dinda B, Das N, Dinda S, Dinda M, SilSarma I. The genus Sida L. - A traditional medicine: Its ethnopharmacological, phytochemical and pharmacological data for commercial exploitation in herbal drugs industry. JOURNAL OF ETHNOPHARMACOLOGY 2015; 176:135-176. [PMID: 26497766 DOI: 10.1016/j.jep.2015.10.027] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/18/2015] [Revised: 10/17/2015] [Accepted: 10/17/2015] [Indexed: 06/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sida L. (Malvaceae) has been used for centuries in traditional medicines in different countries for the prevention and treatment of different diseases such as diarrhea, dysentery, gastrointestinal and urinary infections, malarial and other fevers, childbirth and miscarriage problems, skin ailments, cardiac and neural problems, asthma, bronchitis and other respiratory problems, weight loss aid, rheumatic and other inflammations, tuberculosis, etc. AIMS OF THIS REVIEW To assess the scientific evidence for therapeutic potential of Sida L. and to identify the gaps of future research needs. METHODS The available information on the ethnomedicinal uses, phytochemistry, pharmacology and toxicology of Sida species was collected via a library and electronic searches in SciFinder, PubMed, ScienceDirect, Google Scholar for the period, 1933-2015. RESULTS A variety of ethnomedicinal uses of Sida species have been found in India, China, Afrian and American countries. Phytochemical investigation of this genus has resulted in identification of about 142 chemical constituents, among which alkaloids, flavonoids and ecdysteroids are the predominant groups. The crude extracts and isolates have exhibited a wide spectrum of in vitro and in vivo pharmacological effects involving antimicrobial, analgesic, anti-inflammatory, abortifacient, neuroprotective, cardiovascular and cardioprotective, antimalarial, antitubercular, antidiabetic and antiobesity, antioxidant and nephroprotective activities among others. Ethnopharmacological preparations containing Sida species as an ingredient in India, African and American countries possess good efficacy in health disorders. From the toxicity perspective, only three Sida species have been assessed and found safe for oral use in rats. CONCLUSIONS Pharmacological results supported some of the uses of Sida species in the traditional medicine. Alkaloids, flavonoids, other phenolics and ecdysteroids were perhaps responsible for the activities of extracts of the plants of this genus. No clinical study was reported. The detailed study on mechanism of action of isolates and extracts and their clinical study are needed for their use in modern medicine. More attention should be paid to Sida acuta, Sida cordifolia, Sida spinosa, Sida rhombifolia and Sida veronicaefolia in the domain of diarrhea, dysentery, gastrointestinal and urinary infections, skin ailments, asthma, bronchitis and other respiratory problems, malaria, childbirth and miscarriage problems, cardiac and neural problems, weight loss aid, and rheumatic and other inflammations, etc. Furthermore, detailed study on quality and safety assurance data on available ethnopharmacological preparations is needed for their commercial exploitation in local and global markets.

JOURNAL OF ETHNOPHARMACOLOGY 2015; 175:93-108. [PMID: 26375774 DOI: 10.1016/j.jep.2015.09.002] [Citation(s) in RCA: 91] [Impact Index Per Article: 10.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/20/2015] [Revised: 07/29/2015] [Accepted: 09/03/2015] [Indexed: 05/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This study documents the ethnobotanical and ethnomedicinal importance of plants in the Suva planina mountain region (south-eastern Serbia). It is reflected in their high diversity and their wide range of uses in the treatment of the local population. The aim of this study was a comparative analysis of data collected in the Suva planina region with relevant data from the Western Balkans, which included identifying the 'most popular' plants, as well as those species which are used specifically for treatment solely in the research area. MATERIALS AND METHODS Ethnobotanical research was carried out between 2012 and 2014 and data was collected through both open and semi-structured interviews with locals. A total of 66 people were interviewed (37 women and 29 men), aged between 49 and 90 (with a mean age of 71). RESULTS This study identified 128 plants and 2 fungi which are used in ethnomedicine, 5 plant species used in ethnoveterinary medicine, and 16 plants used for 'other' purposes. Lamiaceae (20), Asteraceae (17), Rosaceae (16), Brassicaceae (5), Alliaceae (4) and Apiaceae (4) have the greatest diversity of species. Results showed that Achillea mellefolium, Allium cepa, Allium sativum, Arctostaphyllos uva-ursi, Gentiana lutea, Hypericum perforatum, Juglans regia, Matricaria chamomilla, Mentha piperita, Plantago lanceolata, Plantago major, Salvia officinalis, Sempervivum tectorum, Tilia cordata and Thymus sepyllum are the 'most popular' medicinal plants (UV=1). Those plants with the most phytotherapeutic uses are Gentiana cruciata (14), H. perforatum (11) and A. sativum (10), while the most common conditions treated with medicinal plants are respiratory (79), urogenital (53), gastrointestinal (51), skin (43) and those relating to the circulatory system (35). A comparative analysis of the data collected in the research area and that from other parts of the Western Balkans showed that there are great similarities within Serbia between Suva planina and the Zlatibor region (37.2%) and Kopaonik Mt. (32.3%), while further afield it is most similar to Bosnia and Herzegovina (40.9%) and Bulgaria (40.6%). Moreover, it was established that 14 plant species and 2 fungi are used only in the Suva planina region, which points to the specificity of the diversity and the sound knowledge of medicinal plants in this region. CONCLUSIONS Our results confirm that medicinal plants are an invaluable resource of the research area and need to be protected as they contribute to an improvement in living standards and the survival of people threatened by unfavourable demographic trends. However, due to over-exploitation, some plants have become exceptionally rare and are under threat, leading to the need for their rational use and protection so as to ensure they are still around for future generations.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The use of plant species for different therapeutic/medicinal purposes is well-entrenched in sub-Saharan Africa. AIM OF THE REVIEW To provide a critical and updated review of the enormous medicinal plant heritage in sub-Saharan Africa with regards to the abundance, importance, conservation status and potential means to help sustain their availability for future generations. METHODS A comprehensive literature search involving different online databases, books and theses were conducted in order to obtain, collate and synthesize available information on various fundamental aspects pertaining to African medicinal plants. RESULTS African biodiversity hotspots are endowed with a high level of endemic species with a significant portion possessing medicinal value. Apart from the extensive ethnobotanical uses of medicinal plants found in Africa, scientific validation of their biological potential such as antimicrobial, antioxidant, anti-inflammatory and anti-diabetic properties have been recognized. Together with the demand arising from their biological efficacies, other anthropogenic factors are exerting conservation strains of the wild population of these medicinal plants. Even though researchers have acknowledged the importance and value of conserving these medicinal plants, several challenges have hampered these efforts on the Continent as a whole. CONCLUSIONS The rich flora occurring in sub-Saharan Africa suggests enormous potential for discovery of new chemical entity with therapeutic value. However, concerted efforts focused on documenting the conservation status of African medicinal plants are pertinent. Application of different biotechnological techniques is needed to sustain these valuable botanical entities, especially to meet increasing pharmaceutical demand. Most importantly, increased public enlightenment and awareness may help eradicate the prejudice against cultivation of medicinal plants.
