Comparison of Lamiaceae medicinal uses in eastern Morocco and eastern Andalusia and in Ibn al-Baytar's Compendium of Simple Medicaments (13th century CE)

Herbal medicine in the Jewish Renaissance rare medical handbook The Guide to the Tree of Life (Sejfer derech ejc ha-chajim)

ETHNOPHARMACOLOGICAL RELEVANCE

The only known copy of Sejfer derech ejc ha-chajim, an anonymous old print, is stored in the Austrian National Library in Vienna. It was written in the Yiddish Ashkenazi language and printed in 1613. The author, a Jewish physician, resided or lived in the Polish-Lithuanian Commonwealth. This rare book, although it was printed over 400 years ago, has not yet been systematically assessed in the ethnomedical context of those times.

AIM OF THE STUDY

A quantitative assessment of the botanical drugs and kinds of healthy diets described in The Guide is presented to recognise the medicinal, diachronic, and botanical outlines of this peculiar rarum.

MATERIALS AND METHODS

To investigate various recipes describing the use of medicinal plants of Jewish culture in the former Polish-Lithuanian Commonwealth, the content of The Guide was analysed. All therapeutic uses of herbal medicines and nutritional recommendations for health were obtained by reviewing the Polish translation of the rare medical handbook. For each plant usage revealed in the text, we noted: Scientific, Common and Yiddish name of the taxon, Plant family, Part of the plant or substance used, Administration, Preparation, Primary pathology, Broad use, and Inferred pathology (ICD-11 and ICPC-3).

RESULTS

Among the 161 recipes, 58 plant taxa and 361 use records were recorded. Additionally, 127 mixtures with 68 plant taxa and 183 use mixture records were noted. 22 diet recipes with 19 plant taxa were also found. These data constitute three separate analyses, according to the intention of the author of The Guide. Formulations using Apiaceae were recommended primarily for gastroenterology and gynecology, while those using Rosaceae for gastroenterology, urology, and neurology. For mixtures, Lamiaceae plants are also represented and used for gastroenterology, respiratory system treatment, and gynecology.

CONCLUSION

The medicinal knowledge described in Sejfer derech ejc ha-chajim fills a gap in contemporary knowledge regarding phyto-medical writing of the Renaissance. The Guide has a form of home first aid kit, used both for medicinal purposes and on the daily menu. In response to current challenges in healthcare, there is a growing interest among researchers in ethnomedicinal sources for the discovery of novel therapeutic compounds. This includes the re-evaluation of formulations and therapeutic indications that have been recognised for centuries. The remedies analysed and detailed in The Guide can provide valuable insights for researchers focused on identifying biologically active therapeutic raw materials of plant origin, thus contributing to advances in modern healthcare.

Antioxidant and antimicrobial effects of essential oils from two salvia species with in vitro and in silico analysis targeting 1AJ6 and 1R4U proteins

The Middle Atlas is a Moroccan territory that serves as an abode to plants with incredible biodiversity, of which aromatic and medicinal plants that have been of folkloric use are a significant component. However, their effective utilization in modern medicine requires the characterization of their phytochemicals to facilitate their entry into drug discovery pipelines. Hence, this study aimed to characterize and investigate the antioxidant activity and antimicrobial effects of the essential oils (EOs) of Salvia lavandulifolia subsp. mesatlantica and Salvia officinalis L. by use of in vitro and in silico assays. Ten phytochemicals were identified in the EOs of S. lavandulifolia, while twenty phytochemicals were identified in S. officinalis. Camphor was the most abundant compound in both species, comprising 26.70% and 39.24% of the EOs of S. lavandulifolia and S. officinalis, respectively. The EOs of both plants exhibited significant DPPH free radical scavenging activity, with S. lavandulifolia and S. officinalis showing estimated scavenging rates of 92.97% and 75.20%, respectively. In terms of Ferric Reducing Antioxidant Power (FRAP), S. officinalis demonstrated a higher value (72.08%) compared to that of S. lavandulifolia (64.61%). Evaluation of the antimicrobial effects of the EOs of S. officinalis and S. lavandulifolia against microorganisms revealed bactericidal activities against Proteus mirabilis and Bacillus subtilis at low concentrations. It showed bactericidal activities against Staphylococcus aureus and Candida albicans at a relatively higher concentration. Molecular docking of antioxidant and antimicrobial proteins offers significant insights into ligand-protein interactions, facilitating the development of innovative therapeutics from the current study. Ultimately, this study identified the phytochemical composition of S. lavandulifolia and S. officinalis and highlighted their potential for therapeutic discovery.

Exploring Iberian Peninsula Lamiaceae as Potential Therapeutic Approaches in Wound Healing

Skin tissue has a crucial role in protecting the human body from external harmful agents, preventing wounds that frequently demand proper healing approaches. The ethnobotanical knowledge of specific regions with further investigation on their medicinal plants has been paramount to create new and effective therapeutical agents, including for dermatological purposes. This review attempts, for the first time, to investigate the traditional applications of Lamiaceae medicinal plants that are already used by local communities in the Iberian Peninsula in wound healing. Henceforward, Iberian ethnobotanical surveys were reviewed, and the information about the traditional wound healing practices of Lamiaceae was comprehensively summarized. Afterwards, the scientific validation of each Lamiaceae species was exhaustively checked. From this, eight out of twenty-nine Lamiaceae medicinal plants were highlighted by their wound-related pharmacological evidence and are in-depth presented in this review. We suggest that future studies should focus on the isolation and identification of the active molecules of these Lamiaceae, followed by robust clinical trials that may confirm the security and effectiveness of such natural-based approaches. This will in turn pave the way for more reliable wound healing treatments.

Thymus hirtus Willd. ssp. algeriensis Boiss. and Reut: A Comprehensive Review on Phytochemistry, Bioactivities, and Health-Enhancing Effects

Members of the Lamiaceae family are considered chief sources of bioactive therapeutic agents. They are important ornamental, medicinal, and aromatic plants, many of which are used in traditional and modern medicine and in the food, cosmetic, and pharmaceutical industries. In North Africa, on the Mediterranean side, there is the following particularly interesting Lamiaceous species: Thymus hirtus Willd. sp. Algeriensis Boiss. Et Reut. The populations of this endemic plant are distributed from the subhumid to the lower arid zone and are mainly employed as ethnomedicinal remedies in the following Maghreb countries: Algeria, Libya, Morocco, and Tunisia. In fact, they have been applied as antimicrobial agents, antispasmodics, astringents, expectorants, and preservatives for several food products. The species is commonly consumed as a tea or infusion and is used against hypercholesterolemia, diabetes, respiratory ailments, heart disease, and food poisoning. These medicinal uses are related to constituents with many biological characteristics, including antimicrobial, antioxidant, anticancer, anti-ulcer, anti-diabetic, insecticidal, and anti-inflammatory activities. This review aims to present an overview of the botanical characteristics and geographical distribution of Thymus algeriensis Boiss. Et Reut and its traditional uses. This manuscript also examines the phytochemical profile and its correlation with biological activities revealed by in vitro and in vivo studies.

Foliar micromorphology of selected medicinal Lamiaceae taxa and their taxonomic implication using scanning electron microscopy

In this research, 25 medicinally used Lamiaceae species belonging to 20 genera have been studied and identified for the nine disorders. We used scanning electron microscopy (SEM) for qualitative and quantitative morphological character identification. The micromorphological characters observed here were important for distinguishing the studied taxa. The highest medicinal values were reported for Vitex negundo and Scutellaria baicalensis for all considered categories except urinary and otorhinolaryngology disorders. The foliar epidermal anatomical characteristics revealed that the micromorphological features of the Lamiaceae species provide taxonomically significant and accurate identification information to delimitate the family species. Moreover, we focused on both qualitative (epidermal cell shape, stomata type, stomatal pore shape, subsidiary cell shape, glandular trichomes, and non-glandular trichome shape) as well as quantitative features (epidermal cell size, stomata size, stomatal pore size, subsidiary cell size, and trichomes size). The trichomes diversity was different in most species' on adaxial and abaxial surfaces. In most species, anomocytic stomata were observed, but other types such as diacytic, paracytic, and tetracytic type stomata were also examined. The diverse pattern of anatomical characters suggests that the studied taxa provide insight evidence for the taxonomic observation of the Traditional Chinese Medicinal plants from the Lamiaceae. This work sets an avenue for future research and taxonomic exploration of medicinal flora through microscopic investigations.

Authentication of the therapeutic Lamiaceae taxa by using pollen traits observed under scanning electron microscopy

Herbal medicines are gaining popularity worldwide for human healthcare because of their therapeutic potential. However, adulteration and use of unauthentic raw herbals as substitutes have become a major issue for the local communities and industry for reasons of safety and efficacy. Therefore, the authentication of medicinal plants before their use in herbal medicines is a need of time. Hence, the present study was designed with an aim, to authenticate the therapeutic Lamiaceous taxa by using pollen traits observed under scanning electron microscopy. Pollen micro-morphological studies solve the problem through discrimination and correct identification of the Lamiaceae species from the adulterants. Based on pollen features, Lamiaceae were further divided into two sub-families Lamioideae (tricolpate) and Nepetoideae (hexa-colpate). The pollen grains of Lamioideae were found as small to medium-sized, tricolpate, radially/bilateral symmetrical, sub-spheroidal and oblate shape. Besides, exine patterns bireticulate, reticulate and micro-reticulate, colpus surface sculpturing as psilate, gemmate, scabrate, and verrucate have also been reported. A significant variation was found in the pattern of the reticulum, thickness, and the number of secondary lumina per primary lumen. Similarly, Nepetoideae has a hexa zono-colpate pollen but tri and tetra zono-colpate pollen have also been observed. Hence, this study contributes to the authentication and correct identification of medicinally important Lamiaceae taxa by using scanning electron microscopic techniques and can help to solve the adulteration problem. Highlights Authentication of medicinally important Lamiceous taxa was carried out through scanning electron microscopic techniques. Chemotaxonomic characterization was used for the accurate identification of the therapeutic taxa. The medicinal, palynological and phytochemical significance of Lamiaceae taxa were evaluated. A significant variation was seen in the palynological traits that help in the determination and authentication of the therapeutic Lamiaceous species. Based on the chemotaxonomic characterization, our study can help to solve the adulteration problem for the reason of safety and efficacy.

Ethnozoology among the Berbers: pre-Islamic practices survive in the Rif (northwestern Africa)

BACKGROUND

Ethnozoological knowledge is less documented than ethnobotanical. With this field study, we aim to record and analyze the Riffian Berber knowledge about the use of animals in traditional human and veterinary medicine. Our research question is what is their knowledge of ethnozoological practices?

METHODS

We performed semi-structured interviews with local inhabitants in Riffian vernacular language. The reliability of the sampling effort was assessed by a rarefaction curve. Data were compared with previous studies in order to determine the geographical and historical extensions of described uses and possible conservation implications for the species used.

RESULTS

We obtained information regarding 107 ethnozoological uses based on 197 use reports. Among the 31 species used, mammals were most frequently cited. Diseases related to the traditional medicinal system were most frequently treated with these resources, as well as those of the respiratory, digestive, and musculoskeletal systems. Thirty percent of uses are associated with magico-religious practices. Only three of the species used are threatened at the global level, two of them extinct in the study area, indicating low potential damage to regional biodiversity from current practices utilizing native animals. Within modern Morocco, Riffians have continued practicing ethnozoological uses anathema to Islam, like the consumption of animals considered impure (dogs, jackals, wild boars, and hyenas).

CONCLUSIONS

The use of primarily mammalian species and of many animal body parts is likely related to the Berber belief in homology between the area of the human body in which the ailment occurs and the corresponding animal body part. These findings unveil the nature of ethnozoological practices, highly linked to folklore and culture-bound conditions, and lacking in the Western empirical rationale for nearly one third of reported uses. The consumption of animals considered impure according to Islam was probably initiated before the conquering of the Maghreb by Arabs in the seventh century and was maintained through the secular isolation of Riffians in mountain areas. This can reflect traditional healing habits being maintained over thousands of years.

The Doctrine of Signatures in Israel-Revision and Spatiotemporal Patterns

The present survey includes forty-three plant species with present-day medicinal applications that can be related to the Doctrine of Signatures (DoS). The main uses are for jaundice (33.3%), kidney stones (20%), and as an aphrodisiac (8%). Ten Doctrine of Signature uses (22.2%) are endemic (to Israel and Jordan); while none of these plant species are endemic to the region at all, their DoS uses are endemic. Summing up of all these data reveals that 73.2% of all uses found in present-day Israel could be considered as related to Muslim traditional medicine. About one quarter (24.4%) of the DoS uses are also common to Europe, and some (8.8%) to India. The two adventive species with DoS uses serve as evidence that the DoS practice is not necessarily based solely on its historical background but is still evolving locally in accordance with changes in the local flora. The current broad geographic distribution of many of the doctrine's uses may serve as indirect evidence of its current prevalence, and not just as a vestigial presentation of ancient beliefs.

In vitro investigation of antioxidant and antihemolytic activities of three Lamiaceae species from Morocco

Background

Lkhzama (Lavandula officinalis), Mard-doch (Origanum majorana), and Lahbak (Ocimum basilicum) are aromatic and medicinal plants widely used in Moroccan folk medicine as a treatment for numerous diseases including liver diseases, rheumatism, and diabetes. This study was undertaken to examine the antioxidant and antihemolytic activities of the aqueous extracts of these plants. The antioxidant activity was evaluated using three in vitro tests: DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) radical scavenging activity, FRAP (ferric reducing antioxidant power assay), and ABTS (2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging assay. The antihemolytic activity of plant extracts was evaluated against AAPH (2,2′-azobis(2-amidino-propane) dihydrochloride)-induced erythrocyte hemolysis.

Results

Our findings showed that all plant extracts displayed significant antioxidant and antihemolytic effects. In fact, among the studied plant extracts, the highest antioxidant power was recorded in Origanum majorana, based on DPPH (IC50 = 12.29 μg/mL), ABTS (226.13 μmol TE/g DW), and FRAP (477.82 μmol TE/g DW) assays. Moreover, the same plant also showed the best membrane protective effect (269.55%). Whereas, Ocimum basilicum exhibited the lowest antioxidant activity using DPPH (IC50 = 42.85 μg/mL), ABTS (IC50 = 226.13 μmol TE/g DW), and FRAP (IC50 = 172.84 μmol TE/g DW) and, thus, the lowest membrane protective effect (182.70%).

Conclusion

This result supports the use of these plants in folk medicine for preventing and treating many diseases, especially those related to oxidative stress.

Phytochemical Analysis and Study of Antioxidant, Anticandidal, and Antibacterial Activities of Teucrium polium subsp. polium and Micromeria graeca (Lamiaceae) Essential Oils from Northern Morocco

The protection of agricultural crops and the preservation of the organoleptic and health qualities of food products represent a major challenge for the agricultural and agro-food industries. Essential oils have received greater attention as alternatives to replace the control strategies based on pesticides against phytopathogenic bacteria and synthetic compounds in food preservation. The aims of this work were to study the chemical composition of Teucrium polium subsp. polium and Micromeria graeca essential oils and to examine their antioxidant and antimicrobial effects. To carry out this work, the chemical composition of the essential oil was determined using gas chromatography (GC) with the detection feature of mass spectrometry (MS). Subsequently, the antioxidant activity was investigated by DPPH and FRAPS assays. The antimicrobial effect was studied against phytopathogenic and foodborne pathogenic bacteria using the disc and the microdilution methods. Our results showed that GC-MS analysis of EOs allowed the identification of 30 compounds in T. polium EO (TPpEO), while 5 compounds were identified in M. graeca EO (MGEO). TPpEO had as major compounds β-pinene (19.82%) and germacrene D (18.33%), while geranial (36.93%) and z-citral (18.25%) were the main components of MGEO. The most potent activity was obtained from MGEO (IC₅₀ = 189.7 ± 2.62 µg/mL) compared to TPpEO (IC₅₀ = 208.33 ± 3.51 µg/mL. For the FRAP test, the highest reducing power was obtained from 1.32 ± 0.1 mg AAE/g of TPpEO compared to MGEO 0.51 ± 0.13 mg AAE/g of EO. Both EOs exhibited varying degrees of antibacterial activities against all the tested strains with inhibition zones in the range of 9.33 ± 0.57 mm to >65 mm and MIC values from 0.19 to 12.5 mg/mL. However, MGEO exhibits an interesting anticandidal effect with inhibition zone 44.33 ± 0.57 mm. The findings of this research establish the riches of EOs on volatile compounds, their important antioxidant activity, and their antimicrobial effect against the bacteria tested.

Geopolitics of bitterness: Deciphering the history and cultural biogeography of Quassia amara L

ETHNOPHARMACOLOGICAL RELEVANCE

Quassia amara L. recently came into the spotlight in French Guiana, when it became the object of a biopiracy claim. Due to the numerous use records throughout the Guiana shield, at least since the 18th century, a thorough investigation of its origin seemed relevant and timely. In the light of the Convention on Biological Diversity (CBD) and the Nagoya protocol, questions about the origin of local knowledge are important to debate.

AIM OF THE STUDY

Defining cultural biogeography as the dynamics through space and time of biocultural complexes, we used this theoretical framework to shed light on the complex biogeographical and cultural history of Q. amara. We explored in particular the possible transfer of medicinal knowledge on an Old World species to a botanically related New World one by enslaved Africans in Suriname.

MATERIALS AND METHODS

Historical and contemporary literature research was performed by means of digitized manuscripts, archives and databases from the 17th to the 21st century. We retrieved data from digitized herbarium vouchers in herbaria of the Botanic Garden Meise (Belgium); Naturalis Biodiversity Center (the Netherlands); Missouri Botanical Garden, the Smithsonian National Museum of Natural History, the Field Museum (USA); Royal Botanic Gardens Kew (UK); the IRD Herbarium, French Guiana and the Museum National d'Histoire Naturelle (France). Vernacular names were retrieved from literature and herbarium specimens and compared to verify the origin of Quassia amara and its uses.

RESULTS

Our exploration of digitized herbarium vouchers resulted in 1287 records, of which 661 were Q. amara and 636 were Q. africana. We observed that the destiny of this species, over at least 300 years, interweaves politics, economy, culture and medicine in a very complex way. Quassia amara's uses are difficult to attribute to specific cultural groups: the species is widely distributed in Central and South America, where it is popular among many ethnic groups. The species spread from Central to South America during the early 18th century due to political and economic reasons. This migration possibly resulted from simultaneous migration by religious orders (Jesuits) from Central America to northern South America and by Carib-speaking Amerindians (from northern South America to Suriname). Subsequently, through colonial trade networks, Q. amara spread to the rest of the world. The absence of African-derived local names in the Guiana shield suggests that Q. africana was not sufficiently familiar to enslaved Africans in the region that they preserved its names and transferred the associated medicinal knowledge to Q. amara.

CONCLUSIONS

Cultural biogeography has proven an interesting concept to reconstruct the dynamics of biocultural interactions through space and time, while herbarium databases have shown to be useful to decipher evolution of local plant knowledge. Tracing the origin of a knowledge is nevertheless a complex adventure that deserves time and interdisciplinary studies.

Ballota nigra L. – an overview of pharmacological effects and traditional uses

Ballota nigra, also known as black horehound is a common medical herb used in folk medicine around the world. First reported mentions of its medical properties and use goes as far as the 13th century. The use of black horehound depends on regions and countries. It is used mostly to treat e.g. mild sleep disorders, nervousness, upset stomach, wound healing. It can be used as an anti-inflammatory, antibacterial, antiprotozoal, antifungal drug. Moreover, it has been reported as a potential cancer drug. This extensive usage is particularly interesting for us. The aim of this review is to present available data on B. nigra pharmacological effects and known traditional uses gathered from a wide range of scientific articles published in 1997–2020.

Characterization, activities, and ethnobotanical uses of Mentha species in Morocco

This work is a summary of the characterization, activities, and ethnobotanical surveys about aromatic and medicinal plants belonging to the genus Mentha in Morocco. The Mentha species investigated are Mentha pulegium, Mentha spicata, Mentha viridis, Mentha suaveolens, Mentha longifolia, Mentha gattefossei, Mentha rotundifolia, and Mentha vulgare, with M. pulegium being the most studied species. M. spicata and M. viridis are poorly explored even though they are daily consumed by Moroccans in tea infusions. The elucidated factors affecting the composition of Mentha essential oils are fertilization, drying conditions, mechanical impedance, NaCl stress, and Gamma irradiation. Investigation of the activities of the Mentha species showed that the main interest was dedicated to addressing the antibacterial effect towards gram+ and gram- bacteria. Essential oils of Mentha species exhibited antifungal, antiviral, antioxidant, insecticidal, licidal, niticidal, allelopathic, antidiabetic, derma-protective, and anticorrosive activities. The ethnobotanical surveys revealed that Mentha species are used in seven regions: Tafilalet, High Atlas, Fez-Boulemane, Taounat, Oujda, Ouazzane, and Rabat. By calculating the Jaccard index, the highest degree of similarity was found between Tafilalet, Rabat, and Oujda regions. The wide use of the Mentha species in Morocco highlights the high ethnobotanical value of the genus.

Palynological characteristics of selected Lamioideae taxa and its taxonomic significance

Lamioideae comprised the second-largest subfamily in Lamiaceae. Although considerable progress has recently been made in the taxonomic study of Lamioideae, the subfamily remains one of the most poorly investigated subfamily in Lamiaceae. Therefore, the present study was designed with the aim to document the pollen micromorphology of some selected Lamioideae taxa and its taxonomic significance from Pakistan. Pollen micromorphological features were observed using scanning electron microscopy. The pollen grains are monad, tricolpate, radially/bilateral symmetrical. The pollen grains were small to medium-sized having oblate, oblate/subspheroidal, and subspheroidal shape. Exine sculpturing was observed as reticulate, microreticulate, and bireticulate. The colpus surface ornamentation was found as verrucate, gemmate, scabrate, and psilate. There was a considerable variation between the species in the micromorphology, that is, the coarseness of the reticulum, thickness of the muri comprising the reticulum and the number of secondary lumina per primary lumen. Hence, this study documented the pollen morphology of some selected taxa of the subfamily Lamioideae from Pakistan and strengthens the taxonomic identification of subfamily based on pollen characters, which helps in the correct identification, discrimination of the species of Lamioideae at generic and species level.

Medicinal plants used in Jeddah, Saudi Arabia: A gender perspective

ETHNOPHARMACOLOGICAL RELEVANCE

Very few studies examining quantitatively gender differences in the knowledge and use of medicinal plants exist for the Arab world. Differences in ethnobotanical knowledge of medicinal plants between men and women in Jeddah are explored here for the first time.

AIM OF THE STUDY

Our study aims to document urban medicinal plant knowledge in Jeddah, and to answer the following questions: (1) What medicinal plants are used by Saudis in Jeddah? (2) To what extent do men and women use medicinal plants? (3) Are plants used by men significantly different to those used by women? And, (4) do men and women learn about medicinal plants in different ways? Given the gendered nature of space and relations in the Arab world, we hypothesise that men and women learn about plants in different ways and that this will contribute to explain any possible differences.

MATERIALS AND METHODS

Ethnobotanical fieldwork took place in Jeddah from August 2018 to September 2019. Individual free-listing, semi-structured interviews and an online survey questionnaire were carried out to document local medicinal plant. In total, 50 men and 50 women were interviewed face-to-face and 344 people responded to the questionnaire, of which 154 were men and 190 were women.

RESULTS

A total of 94 medicinal plant vernacular names were documented representing 85 different plant species belonging to 37 families. Men cited 63 plants (33 plant families) and women 83 (36 plant families). Sixty-one plants were cited by both men and women, two only by men and 22 only by women. Men and women learn in similar ways, but generally use medicinal plants to treat different ailments. Women rely on medicinal plant use to a larger extent.

CONCLUSION

Medicinal plant use is dependent on gendered social roles and experience, as well as preference for biomedicine or medicinal plant use. Men and women use similar plants, but women have greater knowledge that increases with age. Given the food-medicine continuum, women's double role of family food and care providers may explain their expertise in medicinal plant use.

Ethnobotanical study of medicinal plants in the Adrar Province, Mauritania

ETHNOPHARMACOLOGICAL RELEVANCE

Mauritania is a country in which few ethnobotanical studies have been conducted and consequently the ethnomedical data is scarce. Since the geographical region reflects the transition between tropical and Northern Africa, influenced by the Mediterranean floristic region, the traditional knowledge was influenced by several cultures from tropical Africa as well as Arab, Berber and Islamic societies.

AIM OF THE STUDY

This paper aims to explore and compile the diversity of ethnomedical knowledge in one of the regions of Mauritania and to compare the data with similar studies from surrounding territories.

MATERIALS AND METHODS

Surveys and interviews were carried out in 11 villages of Adrar province in northern Mauritania. Data were collected through open, semi-structured interviews (with individuals and focus groups). A sample of 120 people aged between 20 and 70 years, including 24 herbalists and 28 traditional healers was included.

RESULTS

Ethnomedical data for 68 plant species belonging to 27 families were obtained. They are used to treat 50 health conditions grouped in 14 pathological groups. Remedies for digestive system disorders, skin problems and respiratory ailments were among the most frequent indications. Leaves were the most frequently used plant part and remedies generally used as a powder for the various applications and a total of 2'317 use reports were gathered. About 55% of the reported species were not cited previously in the literature focusing on Mauritania and neighbouring countries. Moreover, only 6 species are also cited by Ibn al-Baytar (13th century CE).

CONCLUSIONS

This work shows a promising perspective for future studies, shedding light on the richness and the risk for conservation of traditional knowledge of herbal medicine in Mauritania.

Improvement of Heliciculture by Three Medicinal Plants Belonging to the Lamiaceae Family

Snails were fed with three medicinal plants belonging to the Lamiaceae family (rosemary, sage, and peppermint) in order to test their effects on those animals with high nutritive values. The media of raising were flour containing different percentages of the cited plants ranging from 1% to 9%. The feed had benefits on the raised snails depending on the plant and its percentage. Minerals in those aromatic plants, especially zinc and magnesium, had their effect on protein synthesis in snails fed with those plant percentages. Rosemary was the most profitable plant with the highest protein amount, the lowest mortality rate, and reduced microbial charge. Furthermore, it was a good regulator of the specific catalase activity which confirmed the role of the antioxidant activity of rosemary during raising snails.

Ethnobotanical Knowledge in Sete Cidades, Azores Archipelago: First Ethnomedicinal Report

Knowledge about folk medicines is limited to elder community members of remote communities, like Sete Cidades in the Azores. The Azores, 1300 km west of Portugal, are nine volcanic islands, totalling 2330 km2 of land dispersed by 173,200 km2 in the North Atlantic Ocean. The present study aims to scientifically document the uses of plant species for medicinal purposes, in the Sete Cidades. Twenty-eight community members from 40 to 84 years of age, of whom half were 55 to 64 years old, were interviewed. Twenty-nine taxa were reported as being used for medicinal purposes, ten of which have not been previously reported for ethnomedicinal use in Portugal, with a first record of the use of Morella faya. Leaves were the most used plant part (55%), and decoction the most common preparation mode. The five reported taxa with both the highest use value (0.71-0.25) and relative frequency of citation (0.14-0.11) were Clinopodium menthifolium subsp. ascendens, Aloysia citriodora, Mentha x piperita, Citrus limon and Rosmarinus officinalis. The traditional uses of some of the reported plants are supported by scientific studies, confirming their ethnomedicinal value and the need to preserve local knowledge of folk medicine practices.

A review on traditional uses, phytochemistry and pharmacological activities of the genus Ballota

ETHNOPHARMACOLOGICAL RELEVANCE

The genus Ballota L. (Lamiaceae) comprises 33 to 35 species distributed mainly in temperate and subtropical regions of the world. Some species have been used in folk medicine as antiemetic, antispasmodic, sedative agents, vermifuge, antihemorrhoid and also in treatment of cough, etc. AIM OF THIS REVIEW: This review article aims to provide organized information on the available traditional uses, phytochemical and pharmacological studies of the genus Ballota, and to obtain new insights for further researches.

MATERIALS AND METHODS

Electronic databases, including Web of Science, Science Direct, Google Scholar, Scopus, PubMed, and Springer Link were used as information sources. General web searches were carried out using Google and Yahoo search engines by applying related search terms. Additional information was derived from books and journals in English, Latin and Persian, and also Ph.D. theses and M.Sc. dissertations.

RESULTS

Terpenoids (particularly furanolabdane diterpenoids) and flavonoids were the main phytochemical classes identified in the extracts of Ballota species. Furanolabdane diterpenoids, e.g. ballonigrin, dehydrohispanolone, and hispanolone were reported in many species of Ballota. β-Caryophyllene, caryophyllene oxide, and germacrene D were found as the most common major compounds isolated from the essential oils of the genus Ballota. Sixty-four pharmacological studies conducted on cell lines, microorganisms, and animals were included in this review. Some species of Ballota exhibited various pharmacological activities, including promising antidepressant, anxiolytic, sedative-hypnotic, and antitussive activities in animal models. The pharmacological activities can be attributed to bioactive phytochemicals.

CONCLUSION

The genus Ballota is a valuable source of bioactive compounds with therapeutic potential in different diseases. Some pharmacological studies showed incomplete methodologies and ambiguous findings. Thus, the research designs of pharmacological studies based on traditional uses of Ballota species are strongly needed in cell lines and animal models. More in vitro and in vivo animal studies are required to confirm the safety, clarification of the effective doses, bioactive compounds, and the mechanisms of actions before future clinical studies.

Ethnopharmacology, phytochemistry, and pharmacology of Chinese Salvia species: A review

Effects of surface sterilisation with green synthesised silver nanoparticles on Lamiaceae seeds

Nanoparticles have been used in many areas of biotechnology. In this study, an alternative surface sterilisation method was established for plant tissue cultures. Silver nanoparticles synthesised via green synthesis were used for the surface sterilisation of Lamiaceae seeds (Salvia farinecae, Ocimum basilicum - Large Leaf Italian, Thymus vulgaris, Ocimum basilicum var. purpurascens). Water extracts of dried Alkanna tinctorum rhizomes and Syzygium aromaticum flowers were utilised in the bioreduction of silver ions. The seeds were exposed to 0, 1, 7, 14 and 28 day-old colloidal solutions of silver nanoparticles and their effects on germination and surface sterilisation were determined. Fresh (0 and 1 day-old) colloidal solutions of silver nanoparticles were found very effective on surface sterilisation (100%). Moreover, they showed no negative effect on both germination and morphology of plantlets. It was shown that silver nanoparticles can be used as a surface sterilisation agent and they have no adverse effects on seed germination and in vitro plantlet growth.

Evidence of traditionality of Brazilian medicinal plants: The case studies of Stryphnodendron adstringens (Mart.) Coville (barbatimão) barks and Copaifera spp. (copaíba) oleoresin in wound healing

ETHNOPHARMACOLOGICAL RELEVANCE

The World Health Organization (WHO) recognizes the potential of plants used in secular traditional medicine and considers this an important source of evidence to assess their effectiveness and safety. Brazil is rich in biodiversity and traditional uses based on the Amerindian culture. However, many processes started with the arrival of the Portuguese in the year 1500. The successive economic cycles, for example, led to destruction of native vegetation and an intense cultural erosion. As a consequence, the information about the use of plants in the past centuries are dispersed and without interpretation. In this study a methodology to evidence the traditionality of Brazilian plants was demonstrated using data about barbatimão barks (Stryphnodendron adstringens (Mart.) Coville - Fabaceae) and Copaiba oleoresin (Copaifera spp. - Fabaceae) in wound healing, was established.

MATERIAL AND METHODS

Data about use of the plants were recovered from bibliography published between 1576 and 2011. The books (101) were classified using weights, considering the date of publication and the source of Information. Older books that describe primary information received weight 10, while books written more recently and with secondary information received weight 0.4. A score for each category of medicinal use was calculated based on the books weights and the frequency of citation. A review about the current use of both plants was also performed from ethnobotanical studies published in journals.

RESULTS AND DISCUSSION

The traditional secular use of barks of barbatimão and oleoresin of copaiba to treat wounds was confirmed based on the historic bibliographic research. The most frequent use of barbatimão in a timeline of 500 years of Brazil's history, was as astringent, whereas for copaíba was as healing of skin and mucosal lesions. The continuous and current use of these plants to treat wounds, confirmed by recent ethnobotanical studies, is an indicative of the resilience of these remedies and their effectiveness.

CONCLUSION

The use of preparations containing barbatimão barks and copaiba oleoresin can be considered effective in the treatment of wounds. Nonetheless, it is necessary to improve the quality of the formulas as established by WHO.

The genus Datura L. (Solanaceae) in Mexico and Spain - Ethnobotanical perspective at the interface of medical and illicit uses

ETHNOPHARMACOLOGICAL RELEVANCE

The different species of the genus Datura have been used traditionally by some pre-Columbian civilizations, as well as in medieval rituals linked to magic and witchcraft in both Mexico and Europe. It is also noteworthy the use of different alkaloids obtained from the plants for medicinal purposes in the treatment of various groups of diseases, especially of the respiratory and muscularskeletal systems.

AIM OF THE STUDY

A review of the ethnobotanical uses of the genus Datura in Mexico and Spain has been conducted. We focus on the medicinal and ritualistic uses included in modern ethnobotanical studies, emphasizing the historical knowledge from post-colonial American Codices and medieval European texts. Datura's current social emergency as a drug of recreation and leisure, as well as its link to crimes of sexual abuse is also considered. The work is completed with some notes about the distribution and ecology of the different species and a phytochemical and pharmacological review of Datura alkaloids, necessary to understand their arrival in Europe and the ethnobotanical uses made since then MATERIALS AND METHODS: A literature review and compilation of information on traditional medicinal uses of the genus has been carried out from the main electronic databases. Traditional volumes (codices) have also been consulted in libraries of different institutions. Consultations have been made with the National Toxicological Services of Spain and Mexico for toxicological data.

RESULTS

A total of 118 traditional uses were collected in both territories, 111 medicinal ones to be applied in 76 conditions or symptoms included in 13 pathological groups. Although there are particular medicinal uses in the two countries, we found up to 15 similar uses, of which 80% were previously mentioned in post-Colonial American codices. Applications in the treatment of asthma and rheumatism are also highlighted. Apart from medicinal uses, it is worth noting their cultural and social uses, in the case of Mexico relating to diseases such as being scared, astonishment or falling in love, and in the case of Spain, as a recreational drug and lately, for criminal purposes.

CONCLUSIONS

This review highlights the variety of uses traditionally given to the different species in both territories. The fact that most of the coincident or similar uses in both countries also appear in the classical codices can be found an example of the flow, not only of the plants from America to Europe, but also of their associated information. It is also relevant that particular uses have derived in both countries, reflecting the difference in the cultural factors and traditions linked to rituals and cultural practices. Finally, the significant growth of Datura consumption in recent years as a drug of leisure and recreation, as well as in crimes of sexual submission, should be considered as research of maximum relevance in the field of forensic botany and toxicology.
