SCIENTIFICA 2024; 2024:8645178. [PMID: 38962528 PMCID: PMC11221963 DOI: 10.1155/2024/8645178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 05/26/2024] [Accepted: 06/13/2024] [Indexed: 07/05/2024]
Abstract
Background Phytochemicals are considered the reliable source for the treatment of infection including malaria. Especially, phenols are known as potentially toxic to the growth and development of pathogens, among which flavonoids are the most extensively studied and play more intensive roles in ethnopharmacology. The immunological effect and role of T. diversifolia flavonoids-rich extract in treatment of malaria have therefore been examined in this study. Methods In vitro test against Plasmodium falciparum and 4-day suppressive and Rane's tests against Plasmodium berghei in mice were used to evaluate the antimalarial activities. TNF-α and INF-γ levels, phagocytic tests, and production of oxygen and nitrogen radical were assessed to appreciate the immunomodulatory activity. One-way analysis of variance followed by post hoc Student's t tests was used for data analysis. Results T. diversifolia flavonoids-rich extract at the concentrations ranging from 0.0004 mg/ml significantly (p < 0.05) inhibited in a concentration-dependent manner the growth of trophozoite up to 100% inhibition with 0.025 mg/ml at 24 and 48 hrs. Moreover, T. diversifolia flavonoids-rich extract reduced the level of parasitemia and improved in a dose-dependent manner the survival time of infected mice significantly (p < 0.05) compared to their control in 4-day suppressive test as well as in Rane's test. Additionally, T. diversifolia flavonoids-rich extract increased the TNF-α and INF-γ levels in rats infected by P. berghei. Furthermore, the flavonoid-rich extract enhanced weight of spleen in the rats, the metabolic and phagocytic activities of the peritoneal cells, and the concentration of nitric oxide and oxygen radicals in methylprednisolone-immunocompromised rats compared to the control (p < 0.05). Conclusion The study has revealed that T. diversifolia flavonoids-rich extract through its antiplasmodial and phagocytic activities is a promising treatment of malaria.

Addi YW, Ren ZX, Rutherford S, Ding XY, Guo CA, Zhang X, Zhang S, Liao H, Wang Y. Ethnobotanical study on medicinal plants used by the Yi people in Xiaoliangshan, Yunnan Province, SW China. JOURNAL OF ETHNOPHARMACOLOGY 2024; 323:117683. [PMID: 38184026 DOI: 10.1016/j.jep.2023.117683] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 12/26/2023] [Accepted: 12/27/2023] [Indexed: 01/08/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Yi people in the Xiaoliangshan region in southwest China have a unique practice of combining ritual treatment and traditional medicine to care for patients. Despite increasing urbanization in the area, they have managed to preserve their distinctive lifestyle and extensive knowledge of traditional medicinal plants, setting them apart from other regions. However, there is a lack of systematic documentation on the knowledge of traditional medicinal plants used by the Yi people in Xiaoliangshan. AIM OF THE STUDY This research aims to achieve the following objectives: 1. Document the diversity of medicinal plants used by the Yi people and explore their therapeutic usages. 2. Evaluate and analyze the main types of diseases with a high incidence in the local area and identify the types of medicinal plants used to treat these diseases. 3. Explore the underlying geographical and human factors influencing both disease prevalence and medicinal plant usage. METHODS Ethnobotanical research methods were used to record and analyze the medicinal plants used by the Yi in Xiaoliangshan. Experts identified all plant specimens collected during ethnobotanical field surveys. The types of diseases treated by medicinal plants were classified according to the International Classification of Primary Care -2nd. RESULTS A total of 125 medicinal plants were recorded after interviewing 193 participants. Of the medicinal plants identified, those with over 100 use reports were Paris polyphylla (202 use reports), Taxillus sutchuenensis (183), Artemisia indica (149), and Papaver somniferum (113). A total of 14 disease categories were recorded, with those related to the following categories having higher Informant Consensus factor values (ICF ≥0.85): Pregnancy, Childbearing, Family Planning, General and Unspecified, Urological, Respiratory, Musculoskeletal, and Skin. The highest quantity of medicinal plants is utilized to improve specific diseases and health problems, namely those related to Digestion, Skin, and Musculoskeletal. Fewer plant species were utilized for diseases or health issues associated with Eyes, Psychological, or Pregnancy, Childbearing, and Family Planning. The use reports from the informants also revealed how some medicinal plants are used to treat a variety of diseases or health issues. For instance, Malva pusilla is used for inducing abortion, treating postpartum hemorrhage, and joint sprains; Artemisia indica is used for treating malaria; Argentina lineata is used to remedy tuberculosis and malaria. Taxillus sutchuenensis is used for dealing with cold, pneumonia, and other ailments. CONCLUSIONS The Yi people in Xiaoliangshan have a rich knowledge of traditional medicinal plants. Decoction and wine brewing are the most common processing methods used for these plants, which are utilized to treat a wide range of diseases. The characteristics of the medicinal use of the Yi people reflects the alpine mountainous environment in which they live, and their medical practices are closely related to traditional healing culture. This study enhances our understanding of the Yi traditional medicine via documentation and offers a valuable reference for future research and the development of new drugs.

Exp Parasitol 2023; 249:108521. [PMID: 37011804 DOI: 10.1016/j.exppara.2023.108521] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 03/08/2023] [Accepted: 03/29/2023] [Indexed: 04/03/2023]
Abstract
In the present study, the larvicidal efficacy of the juices of the weeds Lantana camara Linn (L. camara) and Ocimum gratissimum Linn (O. gratissimum) was evaluated against the larvae of the malaria vectors Aedes aegypti, Anopheles subpictus and Culex quinquefasciatus. The freshly prepared juices of leaves were prepared by grinding them and diluting them at concentrations of 25, 50, 75, and 100 ppm. Twenty larvae of each species were introduced in different sterile Petri dishes in aqueous media under a controlled environment for the assessment of biological activity. The larvicidal activity of both juices was evaluated at 6, 12 and 24 hr post-exposure time points by observing the movement of each larva. The obtained data were subjected to probit analysis to determine the lethal concentrations that kill 50% and 90% (LC50 and LC90) of the treated larvae. The results revealed a noticeable larvicidal activity following 24 h of exposure. The juice of L. camara leaves exhibited an LC50 range of 47.47-52.06 ppm and an LC90 range of 104.33-106.70 ppm. Moreover, for the juice of O. gratissimum leaves, the LC50 range was 42.94-44.91 ppm and the LC90 range was 105.11-108.66 ppm. Taken together, the results indicate that the juices of L. camara and O. gratissimum leaves may be useful as effective, economical and eco-friendly larvicidal agents. However, additional studies are needed to explore the bioactive components of the weeds that exhibit larvicidal activity along with their mode of action.

Bisbenzylisoquinolines from Cissampelos pareira L. as antimalarial agents: Molecular docking, pharmacokinetics analysis, and molecular dynamic simulation studies. Comput Biol Chem 2023; 104:107826. [PMID: 36848855 DOI: 10.1016/j.compbiolchem.2023.107826] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 02/06/2023] [Accepted: 02/08/2023] [Indexed: 02/14/2023]
Abstract
Malaria is a major global health issue due to the emergence of resistance to most of the available antimalarial drugs. There is an urgent need to discover new antimalarials to tackle the resistance issue. The present study aims to explore the antimalarial potential of chemical constituents reported from Cissampelos pareira L., a medicinal plant traditionally known for treating malaria. Phytochemically, benzylisoquinolines and bisbenzylisoquinolines are the major classes of alkaloids reported from this plant. In silico molecular docking revealed prominent interactions of bisbenzylisoquinolines such as hayatinine and curine with Pfdihydrofolate reductase (-6.983 Kcal/mol and -6.237 Kcal/mol), PfcGMP-dependent protein kinase (-6.652 Kcal/mol and -7.158 Kcal/mol), and Pfprolyl-tRNA synthetase (-7.569 Kcal/mol and -7.122 Kcal/mol). The binding affinity of hayatinine and curine with identified antimalarial targets was further evaluated using MD-simulation analysis. Among the identified antimalarial targets, the RMSD, RMSF, the radius of gyration, and PCA indicated the formation of stable complexes of hayatinine and curine with Pfprolyl-tRNA synthetase. The outcomes of in silico investigation putatively suggested that bisbenzylisoquinolines may act on the translation of the Plasmodium parasite to exhibit antimalarial potency.

Abstract
Piper longum (family Piperaceae), commonly known as "long-pepper" or "Pippali" grows as a perennial shrub or as an herbaceous vine. It is native to the Indo-Malaya region and widely distributed in the tropical and subtropical world including the Indian subcontinent, Sri Lanka, Middle-East, and America. The fruits are mostly used as culinary spice and preservatives and are also a potent remedy in various traditional medicinal systems against bronchitis, cough, cold, snakebite, and scorpion-sting and are also used as a contraceptive. Various bioactive-phytochemicals including alkaloids, flavonoids, esters, and steroids were identified from the plant extracts and essential oils from the roots and fruits were reported as antimicrobial, antiparasitic, anthelminthic, mosquito-larvicidal, antiinflammatory, analgesic, antioxidant, anticancer, neuro-pharmacological, antihyperglycaemic, hepato-protective, antihyperlipidaemic, antiangiogenic, immunomodulatory, antiarthritic, antiulcer, antiasthmatic, cardioprotective, and anti-snake-venom agents. Many of its pharmacological properties were attributed to its antioxidative and antiinflammatory effects and its ability to modulate a number of signalling pathways and enzymes. This review comprehensively encompasses information on habit, distribution, ethnobotany, phytochemistry, and pharmacology of P. longum in relation to its medicinal importance and health benefits to validate the traditional claims supported by specific scientific experiments. In addition, it also discusses the safety and toxicity studies, application of green synthesis and nanotechnology as well as clinical trials performed with the plant also elucidating research gaps and future perspectives of its multifaceted uses.

Abstract
Background Malaria is one of the leading causes of morbidity in the world. It is a significant health concern in most developing countries, including Ghana. Even though there are several orthodox medications used for decades in treating malaria effectively, a substantial number of individuals in developing countries are resorting to the use of herbs in the treatment of malaria. The study aim at exploring the practices of herbal management of malaria among trading mothers in Shai Osudoku District, Accra. Methods A qualitative approach with an exploratory, descriptive design was adopted in analyzing the research problem. Purposive sampling technique was used to select twenty (20) participants to partake in a face-face interview, guided by a semi-structured interview guide. The data were transcribed verbatim and analysed by adopting content analysis. Results Two significant themes and seven subthemes were generated following the analysis of this study. The main themes were; preferences for herbal malaria treatment and the practices and effectiveness of herbal medicine used for malaria treatment. It was worth noting that the women’s cultural beliefs did not influence their preference for herbal malaria treatment. The main challenge associated with the herbal malaria treatment was inappropriate dosage specification. Conclusion This study discovered that several factors influenced participants’ preferences for malaria treatment. Participants further listed some traditional ways of treating malaria which implies that there is herbal malaria practice. However, literature in this area is inadequate, and most herbs lack specifications for use. It is therefore recommended that future research focus on scientific herbal malaria treatment. Also, regulating bodies should ensure that quality herbal drugs are sold for consumption.

Abstract
Aphis craccivora Koch is a polyphagous and major pest of leguminous crops causing significant damage by reducing the yield. Repeated application of synthetic insecticides for the control of aphids has led to development of resistance. Therefore, the present study aimed to screen the insecticidal activity of root/stem extracts/fractions, and pure molecules from Cissampelos pareira Linnaeus against A. craccivora for identification of lead(s). Among root extract/fractions, the n-hexane fraction was found most effective (LC50 = 1828.19 mg/L) against A. craccivora, followed by parent extract (LC50 = 2211.54 mg/L). Among stem extract/fractions, the n-hexane fraction (LC50 = 1246.92 mg/L) was more effective than the water and n-butanol fractions. Based on GC and GC-MS analysis, among different compounds identified in the n-hexane fraction of root and stem, ethyl palmitate (known to possess insecticidal activity) was present in the highest concentration (24.94 to 52.95%) in both the fractions. Among pure molecules, pareirarineformate was found most effective (LC50 = 1491.93 mg/L) against A. craccivora, followed by cissamine (LC50 = 1556.31 mg/L). Parent extract and fractions of C. pareira possess promising activity against aphid. Further, field bio-efficacy studies are necessary to validate the current findings for the development of botanical formulation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cissampelos pareira, a well-known medicinal climber-plant of the Menispermaceae family, has been extensively used in the traditional medicinal system since the ancient time for the treatment of numerous diseases such as ulcer, wound, rheumatism, fever, asthma, cholera, diarrhoea, inflammation, snakebite, malaria, rabies, and also recommended for blood purification. AIM OF THE REVIEW The main purpose of this review is to provide updated information on ethnopharmacology, phytochemistry, chromatographic and spectroscopic analysis, pharmacology, and toxicology of C. pareira along with the possible future research. This information will help to provide a foundation for plant-based drug discovery in the near future. MATERIAL AND METHODS The online databases such as Scifinder, Web of Science, PubMed, and Google Scholar were used to collect electronically available literature data on C. pareira. Ayurveda text is searched for the traditional uses of this plant in India. The published books are also searched for the information on this plant. Our search was based on traditional uses, botany, phytochemistry, and pharmacological potential by using "Cissampelos pareira" as the keyword. RESULTS To date, approximately 54 phytomolecules have been isolated and characterized from C. pareira including mainly isoquinoline alkaloids along with few flavonoids, flavonoid glycosides, and fatty acids. The crude extracts of C. pareira have shown various pharmacological activities such as antipyretic, anti-inflammatory, antiarthritic, antiulcer, antidiabetic, anticancer, antifertility, antimicrobial, antioxidant, antivenom, antimalarial, and immunomodulatory, etc. The chemical fingerprinting of C. pareira carried out using HPTLC, HPLC, UPLC, LC-MS, and GC-MS, revealed the presence of alkaloids (isoquinoline alkaloids), fatty acids, and flavonoid glycosides. Moreover, the toxicological assessment of C. pareira has been moderately investigated, which requires further comprehensive studies. CONCLUSION Comprehensive literature survey reveals that till date, remarkable growth has been made on phytochemistry and pharmacology of C. pareira reflecting the great medicinal potential of this plant. Although some of the traditional uses have been well clarified and documented by modern pharmacological analysis, the correlation between its pharmacological activities and particular phytoconstituents still needs to be validated. Furthermore, there is partial data available on most of the pharmacological studies, along with incomplete toxicological screening. Future research needs to pay more attention to pharmacological studies of C. pareira via pre-clinical and clinical trials. Additionally, scientific validation of traditional knowledge of C. pareira is vital for ensuring safety, efficacy, and mechanism of action before clinical uses.

Ethnobotanical survey and evaluation of traditional mosquito repellent plants of Dai people in Xishuangbanna, Yunnan Province, China. JOURNAL OF ETHNOPHARMACOLOGY 2020; 262:113124. [PMID: 32730874 DOI: 10.1016/j.jep.2020.113124] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/04/2019] [Revised: 06/15/2020] [Accepted: 06/17/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Dengue is one of the most important pervasive diseases in many regions of the world, including China. There is an urgent need for new repellents, including plant derivatives, due to the resistance, toxicity, and non-degradability of synthetic insecticides. Traditional plant-based remedies may provide potential avenues for developing new strategies. AIMS OF THE STUDY The aims of this study were to 1) document the traditional mosquitoes repellent plants used by the Dai people of Xishuangbanna, China; 2) screen out new efficient mosquito repellent plants as candidates for further study. MATERIALS AND METHODS During the period August 2016 to July 2017, five field surveys were conducted in 16 villages of Xishuangbanna. A total of 81 informants (44 males and 37 females) were interviewed using semi-structured questions to collect detailed information on the plants they use to prevent mosquito bites. Ten plants with higher popularity and larger resource were collected and extracts were prepared by hydro-distillation or with petroleum ether. Extracts were tested for adult Aedes albopictus repellency using a human-bait cage. Firstly, repellency was determined as the Minimum Effective Dosage (MED) per minute at which 1% of the mosquito bite through the treated cloth. Secondly, five plant extracts with lower MEDs were tested the repellent longevity of different concentrations. RESULTS Eighteen plants were documented as being used in traditional remedies against mosquitoes. The methods for controlling mosquitoes were diverse: direct burning was used for most plants (16 species), followed by smearing (5 species), and placing (5 species). Laboratory analyses confirmed that ten plants did exhibit mosquito repellent activity. Of them, Artemisia indica, Nicotiana tabacum, Blumea balsamifera, Vitex trifolia, and Chromolaena odorata showed good mosquito repellency with MEDs of 0.015, 0.061, 0.090, 0.090, and 0.105 mg/cm2, respectively. The protection rate provided by A. indica is also the highest among five plants. Although it provides complete protection time of only 30 min at 0.45 mg/cm2 concentration, its repellency within 2 h is not significantly different from that of DEET. CONCLUSION Dai villagers in Xishuangbanna have a rich, diverse and scientific knowledge of plant-based mosquito repellents. Laboratory experiments screened out several plants as candidates for mosquito repellents, of which Artemisia indica was the most promising candidate plant.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 262:113185. [PMID: 32726676 DOI: 10.1016/j.jep.2020.113185] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/24/2019] [Revised: 06/12/2020] [Accepted: 07/14/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cissampelos pareira is used traditionally in India as a remedy for the treatment of various diseases including malaria but the active ingredients responsible for antiplasmodial activity have not yet been investigated. AIM OF THE STUDY The identification and quantification of compounds responsible for antiplasmodial activity in different parts (leaf, stem and root) of C. pareira is the target of current study. MATERIAL AND METHODS The hydro ethanolic parent extracts of different parts of C. pareira and fractions prepared from these extracts were evaluated against Pf3D7 (chloroquine sensitive) and PfINDO (chloroquine resistance) strains in culture to quantify the IC50 for extracts and fractions. Promising fractions of root part of plant were subjected to silica gel column chromatography to obtain pure compounds and their structures were elucidated by detailed spectroscopic analysis. Pure compounds were also tested against Pf3D7 and PfINDO strains. A rapid and simple UPLC-DAD method was developed for the identification and quantification of pharmaceutically important metabolites of C. pareira. RESULTS Among different extracts, the hydro ethanolic extract of root part of C. pareira was found most active with IC50 values (μg/ml) of 1.42 and 1.15 against Pf 3D7 and Pf INDO, respectively. Tested against Pf 3D7 the most potent fractions were root ethyl acetate fraction (IC50 4.0 μg/ml), stem water fraction (IC50 4.4 μg/ml), and root water fraction (IC50 8.5 μg/ml). Further, phytochemical investigation of active fractions of root part led to the isolation and characterization of a new isoquinoline alkaloid, namely pareirarine (8), along with five known compounds magnoflorine (5), magnocurarine (10), salutaridine (11), cissamine (13) and hayatinine (15). Hayatinine (15), a bisbenzylisoquinoline alkaloid, isolated from root ethyl acetate fraction was most promising compound with IC50 of 0.41 μM (Pf INDO) and 0.509 μM (Pf 3D7). Magnocurarine (10) and cissamine (13) were also found active with IC50 values of 12.51 and 47.34 μM against Pf INDO and 12.54 and 8.76 μM against Pf 3D7, respectively. A total of thirty compounds were detected in studied extracts and fractions, structures were assigned to 15 of these and five of these biologically important compounds were quantified. Isolation of saluteridine (11) from C. pareira and the evaluation of antiplasmodial activity of pure compound from C. pariera is disclosed for the first time. CONCLUSION This study concludes that the antimalarial potential of C. pareira may be attributed to isoquinoline type alkaloids present in this plant and also provides the scientific evidence for the traditional use of this plant in treatment of malaria.

Abstract
Traditional agroforestry systems are designed to provide maximum and diverse yield (ranging from agricultural crops, forest trees, livestock and fish) to people. They also act as sources of food and shelter to wild animals leading to crop destruction, livestock depredation and injuries to people giving rise to negative human-wildlife interactions. The present study was carried out in three different agroforestry systems namely tea gardens, homegardens, and agrisilvicultural systems in Assam to document the attitude of people towards wild animals which damage the crops and livestock, through questionnaire surveys. In agroforestry systems, 13 animals were reported as destructive; rodents at 13% followed by Indian Hare at 12%. The least destructive were birds and bats with 4% each. In tea gardens majority of the people killed animals for meat (95%) and the most common method for killing was the use of catapults (77%). In homegardens and agrisilvicultural systems, owners chased the animals away (82%) by using catapults (68%). Hunting of animals and intolerance of people towards crop destruction and livestock depredation done by wild animals were the two main reasons causing negative human-wildlife interactions in agroforestry systems. The present study concludes that wildlife species found in the agroforestry system in Assam were threatened by local inhabitants and thus, a suitable conservation awareness and policy action plan should be developed in consultation with the owners of agroforestry systems by considering the ecological significance of the wildlife species found therein.

Forest Fevers: traditional treatment of malaria in the southern lowlands of Laos. JOURNAL OF ETHNOPHARMACOLOGY 2020; 249:112187. [PMID: 31476439 DOI: 10.1016/j.jep.2019.112187] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/30/2019] [Revised: 08/12/2019] [Accepted: 08/26/2019] [Indexed: 05/20/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Malaria is still a highly challenging public health issue in southern Lao PDR, with increasing cases of artemisinin resistance and Plasmodium vivax infections which are more complicated to treat. Traditional medicine has a long history of use in Laos, and is primarily practised by traditional village healers, who possess unique bodies of transmitted knowledge focused on herbal prescriptions, including those for the treatment of malaria. Villagers also use plants for healthcare in the home. The aim of the study is to document local fever concepts and use of herbal remedies, and examine whether they may have potential as complementary treatments against malaria. MATERIALS AND METHODS The study took place in Champasak province in the far south of Laos, in primarily lowland areas. First, 35 traditional healers across the 10 districts of the province were interviewed to elicit details about knowledge and treatment of fevers. Second, a household survey was conducted in a village in a malaria-endemic area; 97 households were interviewed on fever incidence, differentiation, treatment-seeking behaviour and knowledge of plant-based remedies for fevers. Plants indicated by both healers and villagers were collected and voucher specimens deposited in the herbarium of the National University of Laos for identification. RESULTS Malaria is a well-known pathology among the healers and villagers of lowland Champasak province; biomedical treatments are preferentially used, but traditional medicine is a popular complementary method, especially in chronic cases with additional symptoms. 30 different fever types were recorded, which were usually named symptomatically, and grouped into 12 categories. Some were described as forms of malaria, which was conceived as a dynamic, changing pathology affecting many body systems. Healers formulate treatments based on symptoms and the person's constitution, and with the intention of creating specific pharmacological actions associated with temperature or flavours. 11 of the healers gave prescriptions for malaria (27 in total), including 47 identified plant species. The most-used plants (4 or more use-reports) were also the most cited in the literature for use against malaria, demonstrating a correspondence between Lao healers and other traditional medical systems. Furthermore, some of these species show promising results for future research, especially Amorphophallus paeniifolius (Dennst.) Nicolson and Alocasia macrorrhizos (L.) G. Don. CONCLUSION Traditional healers are important actors in the treatment of malaria in southern Laos, and herbal remedies should be evaluated further by the use of reverse treatment outcome trials, especially those which may be of use as complementary remedies in treating P. vivax. Initiatives on knowledge transmission, medicinal plant conservation and healthcare integration are also urgently needed.

JOURNAL OF ETHNOPHARMACOLOGY 2019; 234:245-289. [PMID: 30658182 DOI: 10.1016/j.jep.2019.01.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/04/2018] [Revised: 01/10/2019] [Accepted: 01/14/2019] [Indexed: 06/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Mauritius is famous for its floricultural diversity and traditions practiced across the island by various ethnic groups. During the British rule in the 1835s, Indian indentured labourers migrated to Mauritius and played a very important role in shaping the Mauritian culture. They brought along their high heritage of traditional knowledge of certain medicinal herbs and spices. Nonetheless, there has been no comparative study to investigate whether these past traditional knowledge are still preserved in Mauritius and India. AIM OF THE STUDY To document and compare the traditional uses of medicinal herbs and spices brought by Indian indentured labourers with their current uses in Mauritius and India, and to review pharmacological studies of such plants. MATERIALS AND METHODS Locally published textbooks, research dissertations, and relevant records from the 'Mauritiana' section of the University of Mauritius library were scrutinised for possible early records of such herbs and spices brought by Indian indentured immigrants. Field trips and site visits to Mauritius Herbarium and The National Folk Museum were conducted to gather data on their traditional uses as practiced by the Indian indentured immigrants. A literature search was performed to gather the current ethnomedicinal uses of these plants in Mauritius and India using key databases such as ScienceDirect and PubMed, as well as thesis from local university website. Pharmacological studies on these plants were also reviewed in an attempt to compare the ethnomedicinal uses against reported ailments. RESULTS Indian labourers brought 18 medicinal plants for medicinal purposes as documented at the folk museum of Indian Immigration. Piper betle L., Azadirachta indica A. Juss., and Curcuma longa L. were common plants used by Indian indentured immigrants against a wide range of ailments. Data obtained from recent ethnomedicinal surveys revealed that A. indica and C. longa were the most traditionally used plants in India, while in Mauritius, C. longa was the most popular plant followed by Allium sativum L. and Ocimum tenuiflorum L. It was also found that all these plants are currently being used against a wide range of diseases in both countries. In addition, several studies have highlighted the pharmacological properties such as analgesic, anti-inflammatory, anti-microbial, anti-pyretic, and anti-diabetic for some plants. CONCLUSION This investigation can be considered as a first attempt to document and compare traditional knowledge of medicinal plants brought by Indian immigrants. We observed that some of these knowledge are preserved and still practiced in Mauritius. It is anticipated that this study will revive the interest in safeguarding and promoting the ancestral knowledge on the uses of such plants.

Abstract
ETHNOBOTANICAL RELEVANCE Malaria is a serious public health problem especially in sub-Saharan African countries such as Nigeria. The causative parasite is increasingly developing resistance to the existing drugs. There is urgent need for alternative and affordable therapy from medicinal plants which have been used by the indigenous people for many years. AIM OF STUDY This study was conducted to document the medicinal plant species traditionally used by the people of Nsukka Local Government Area in south-eastern Nigeria for the treatment of malaria. METHODS A total of 213 respondents, represented by women (59.2%) and men (40.8%), were interviewed using a semi-structured questionnaire. The results were analysed and discussed in the context of previously published information on anti-malarial and phytochemical studies of the identified plants. RESULTS The survey revealed that 50 plant species belonging to 30 botanical families were used in this region for the treatment of malaria. The most cited families were Apocynaceae (13.3%), Annonaceae (10.0%), Asteraceae (10.0%), Lamiaceae (10.0%), Poaceae (10.0%), Rubiaceae (10.0%) and Rutaceae (10.0%). The most cited plant species were Azadirachta indica (11.3%), Mangifera indica (9.1%), Carica papaya (8.5%), Cymbopogon citratus (8.5%) and Psidium guajava (8.5%). CONCLUSION The present findings showed that the people of Nsukka use a large variety of plants for the treatment of malaria. The identified plants are currently undergoing screening for anti-malarial, toxicity and chemical studies in our laboratory.

Abstract
Vitex spp. have been reported as constituents of herbal preparations, namely Vitex peduncularis, commonly used in Asian countries. Unlike other species extensively investigated, reports on the biological activities and chemical profile of V. peduncularis are still scarce. In this work, the polyphenolic profile of V. peduncularis stem bark was unveiled, revealing a high content of apigenin and luteolin derivatives. More than 20 polyphenols were identified and quantitated for the first time, including C-rhamnosyl flavones infrequently reported. Regarding potential anti-inflammatory properties, the methanolic extract of the stem bark significantly reduced the levels of NO in macrophages, which may be a consequence of scavenging effect upon •NO. Significant inhibition of phospholipase A2 activity was also noted. Consequently, the therapeutic applicability of this edible plant is also broadened due to the anti-inflammatory properties found.

Abstract
Background Resistance development in human malaria parasites against commonly used antimalarial drugs has necessitated the scientific exploration of traditionally used antimalarial plants. Plant derivatives have been used for curing malaria historically. The present study involves in vitro evaluation of two medicinally important plants Aristolochia griffithii and Thalictrum foliolosum DC used in antimalarial chemotherapy by the tribes of northeast India. Method Chloroform, ethyl acetate and n–butanol extracts of Aristolochia griffithii and Thalictrum foliolosum DC were evaluated in vitro against chloroquine sensitive (SS) and chloroquine resistance strains (RS) of P. falciparum. The tests were conducted following WHO standard method and the inhibition of parasite (IC50) was calculated. Results In A. griffithii, the IC50 value for ethyl acetate extracts against SS was 6.2 ± 0.02 μg/ml and found to be lower than chloroform extracts, which exhibited an IC50 value of 14.1 ± 0.1 μg/ml (t = 191.1; p < 0.0001). The IC50 values of both chloroform and ethyl acetate extracts for RS were higher as compared to the SS (p < 0.0001). In T. foliolosum DC the IC50 concentration of chloroform extracts for SS and RS were 0.5 ± 0.0 and 1.1 ± 0.0 μg/ml respectively (t = 54.2; p < 0.0001). Conclusion The present findings, although preliminary, but scientifically demonstrate that identification and isolation of active compounds of these two plant materials and testing against different Plasmodium species could lead to the development of potential antimalarial drugs for future.

[PMID: 24997389 DOI: 10.1016/j.jep.2014.06.054] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/31/2014] [Revised: 05/22/2014] [Accepted: 06/24/2014] [Indexed: 06/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cissampelos species have a rich history of traditional use, being used for both therapeutic and toxic properties. It is traditionally applied therapeutically in a diverse range of conditions and diseases including asthma, cough, fever, arthritis, obesity, dysentery, snakebite, jaundice and heart, blood pressure and skin-related problems. Conversely, it was traditionally included in preparations of curare applied as arrow poison during hunting to cause death of animals by asphyxiation. This review unites the ethnobotanical knowledge on Cissampelos with the phytochemistry and pharmacological activity which has been explored thus far. In addition, it identifies knowledge gaps and suggests further research opportunities. METHODS The available electronic literature on the genus Cissampelos was collected using database searches including Scopus, Google Scholar, Pubmed, Web of Science, etc. The searches were limited to peer-reviewed English journals with the exception of books and a few articles in foreign languages which were included. RESULTS The literature revealed that pharmacological activity including analgesic and antipyretic, anti-inflammatory, anti-allergic, bronchodilator, immunomodulatory, memory-enhancing, antidepressant, neuroprotective, antimicrobial, antimalarial, antiparasitic, anti-ulcer, anticancer, anti-oxidant, cardiovascular, muscle-relaxant, hepatoprotective, antidiabetic, antidiarrhoeal, antifertility, and antivenom activity have been confirmed in vitro and/or in vivo for various Cissampelos species. Cissampelos pareira L. and Cissampelos sympodialis Eichl. are the most explored species of this genus and the smallest number of studies have been conducted on Cissampelos laxiflora Moldenke and Cissampelos tenuipes Engl. Many alkaloids isolated from Cissampelos such as warifteine, methylwarifteine, berberine, hayatin and hayatidin showed promising anti-allergic, immunosuppressive, antidepressant, anticancer, vasodilatory and muscle-relaxant activities. CONCLUSION The plants of this genus are used in traditional medicine for the treatment of various ailments. These plants are a rich source of bioactive bisbenzylisoquinoline and aporphine alkaloids together with other minor constituents. Although these plants are reputable and revered in various traditional medicine systems, many have not yet been screened chemically or pharmacologically and so there is a vast amount of research still to be conducted to validate their traditional use.

Abstract
Malaria continues to be a major global public health problem with 3.3 billion people at risk in 106 endemic countries. Globally, over 1000 plants have been used as potential antimalarials in resource-poor settings due to fragile health-care systems and lack of accessibility and affordability of artemisinin-based combination therapies (ACTs). Although many believe that the use of medicinal plants that have folklore reputations for antimalarial properties is relatively safe, many herbs may be potentially toxic due to their intrinsic adverse side effects. Therefore, herbal-derived remedies require powerful and deep assessment of their pharmacological qualities to establish their mode of action, safety, quality, and efficacy. In addition, the evolution of drug resistance also demands new antimalarial agents. This can be achieved by forming a vibrant antimalarial discovery pipeline among all stakeholders, including traditional healers, ethnobotanists, scientists, entomologists, pharmacists, and research institutions, for the isolation and characterization of the bioactive compounds with the ultimate objective of finding novel modes of action antimalarial compounds that can be used to fight against drug-resistant malarial parasites.

Malaria control is compromised worldwide by continuously evolving drug-resistant strains of the parasite demanding exploration of natural resources for developing newer antimalarials. The northeastern region of India is endemic for malaria characterized by high prevalence of drug-resistant Plasmodium falciparum strains. Many plants are used by the indigenous communities living in the northeast India in their traditional system of medicine for the treatment of malarial fever. Folklore claim of antimalarial property of one such plant Brucea mollis was evaluated in vitro and in vivo for antiplasmodial activity. Crude extracts from dried B. mollis root powder were prepared through soxhlet extraction using petroleum ether, methanol, and water sequentially. Methanol extract was further partitioned between chloroform and water. These extracts were tested in vitro against laboratory-adapted chloroquine-sensitive and chloroquine-resistant strains of P. falciparum. In in vitro evaluation, extracts were found more active on the chloroquine-sensitive strain. Methanolic-chloroform (IC(50) 5.1 μg ml(-1)) and methanolic-aqueous (IC(50) 13.9 μg ml(-1)) extracts recorded significant in vitro antiplasmodial activity which was also supported by their promising in vivo activity (ED(50) 72 and 30 mg kg(-1) bw day(-1), respectively) against chloroquine-resistant Plasmodium yoelli N-67 strain in Swiss albino mice. Methanolic-aqueous extract-treated mice survived on average for 14 days that was comparable to the reference drug chloroquine. This is the first report of antiplasmodial activity of B. mollis validating the traditional use of this plant as antimalarial in the northeast India and calls for further detailed investigations.

Abstract
Despite recent scientific advancement and globalization, the system of traditional medicine and complementary/alternative medicine is considered as a primary health care modality in the resource-constrained health care settings. Herbal medicinal system has been postulated and established through empirical observation and trial and error experiments since time immemorial to maintain good health and alleviate ailments and diseases. Earlier, the importance of traditional medicinal plants and phytotherapy have often been disregarded and undervalued. Presently revitalization and renewed interest on traditional medicinal plants has been observed among the public and scientific community. However, several daunting challenges need to be flagged effectively and immediately for the promotion of traditional medicinal plants. The collaborative efforts of ethnobotanists, anthropologists, pharmacists, and physicians could be a workable strategy to evaluate and validate the usage of traditional medicinal plants with the modern scientific methods and innovative techniques. Furthermore, conducting clinical trials to assess their efficacy and human safety is imperative and inevitable.

Abstract
BACKGROUND The present paper documents the uses of plants in traditional herbal medicine for human and veterinary ailments, and those used for dietary supplements, religious purpose, local beverage, and plants used to poison fish and wild animals. Traditional botanical medicine is the primary mode of healthcare for most of the rural population in Arunachal Pradesh. MATERIALS AND METHODS Field research was conducted between April 2006 and March 2009 with randomly selected 124 key informants using semi-structured questionnaire. The data obtained was analyzed through informant consensus factor (FIC) to determine the homogeneity of informant's knowledge on medicinal plants. RESULTS We documented 50 plants species belonging to 29 families used for treating 22 human and 4 veterinary ailments. Of the medicinal plants reported, the most common growth form was herbs (40%) followed by shrubs, trees, and climbers. Leaves were most frequently used plant parts. The consensus analysis revealed that the dermatological ailments have the highest FIC (0.56) and the gastro-intestinal diseases have FIC (0.43). FIC values indicated that there was high agreement in the use of plants in dermatological and gastro-intestinal ailments category among the users. Gymnocladus assamicus is a critically rare and endangered species used as disinfectant for cleaning wounds and parasites like leeches and lice on livestocks. Two plant species (Illicium griffithii and Rubia cordifolia) are commonly used for traditional dyeing of clothes and food items. Some of the edible plants recorded in this study were known for their treatment against high blood pressure (Clerodendron colebrookianum), diabetes mellitus (Momordica charantia), and intestinal parasitic worms like round and tape worms (Lindera neesiana, Solanum etiopicum, and Solanum indicum). The Monpas of Arunachal Pradesh have traditionally been using Daphne papyracea for preparing hand-made paper for painting and writing religious scripts in Buddhist monasteries. Three plant species (Derris scandens, Aesculus assamica, and Polygonum hydropiper) were frequently used to poison fish during the month of June-July every year and the underground tuber of Aconitum ferrox is widely used in arrow poisoning to kill ferocious animals like bear, wild pigs, gaur and deer. The most frequently cited plant species; Buddleja asiatica and Hedyotis scandens were used as common growth supplements during the preparation of fermentation starter cultures. CONCLUSION The traditional pharmacopoeia of the Monpa ethnic group incorporates a myriad of diverse botanical flora. Traditional knowledge of the remedies is passed down through oral traditions without any written document. This traditional knowledge is however, currently threatened mainly due to acculturation and deforestation due to continuing traditional shifting cultivation. This study reveals that the rural populations in Arunachal Pradesh have a rich knowledge of forest-based natural resources and consumption of wild edible plants is still an integral part of their socio-cultural life. Findings of this documentation study can be used as an ethnopharmacological basis for selecting plants for future phytochemical and pharmaceutical studies.
