Ethnopharmacological Survey of Medicinal Plants Used in Traditional Treatment of Kidney Diseases in Fez–Meknes Region, Morocco

The purpose of this study was to inventory and collect information on plants and mixtures commonly used by herbalists to treat kidney disease in the Fez–Meknes region. We also aimed to compare the results obtained with the results of the other studies and exploit the correlations between different factors. An ethnopharmacological survey was conducted from 289 local herbalists in eight different areas of Fez–Meknes region. Ethnomedicinal uses and ethnobotanical indices were analyzed using quantitative tools, i.e., the total number of citation (TNC), use value (UV), family use value (FUV), fidelity level (FL), and rank order priority (ROP). Statistical analyses such as Pearson correlation and chi-squared test were performed to delineate any correlation. Two hundred and eighty-nine herbalists were questioned. Sixty-nine plant species belonging to 38 families were cited by herbalists for traditional treatment of kidney disease. The highest value of UV was obtained for Herniaria glabra L. (UV = 0.79), and Caryophyllaceae was the family frequently cited (FUV = 0.795). Ammodaucus leucotrichus Coss. & Dur. had the highest value of FL with a value of 100%, and the highest value of ROP was recorded for Herniaria glabra L. (ROP = 91%). Sociodemographic characteristics had a significant impact on the knowledge of toxic plants. Our study has revealed a cultural heritage linked to herbalism and a great wealth of medicinal plants, whose valorization and protection are necessary. Several studies are needed to sensitize herbalists and population on the danger of toxic plants, to extract chemical compounds from the main plants used, and to evaluate their toxicity.

Assessing medicinal plants traditionally used in the Chirang Reserve Forest, Northeast India for antimicrobial activity

Ethnopharmacological relevanceKnowledge on the use of plants for different ailments by the tribals of the Chirang Reserve Forest (CRF, Northeast India) was used to assess the potential of these plants for treating viral, bacterial and fungal infections. Materials and methodsFieldwork in the CRF documented the use of plants for the treatment of various human ailments. The ethnobotanical data were analysed using different quantitative indices viz. Informant Consensus Factor (ICF), Relative Frequency Citation (RFC), Fidelity Level (FL), Relative Popularity Level (RPL) and Rank Order Priority (ROP). For each plant, four extracts were prepared with different solvents (water, ethanol, acetone and hexane) and tested for bioactivity such as antiviral (Enterovirus 71) and antimicrobial (E. coli, S. aureus, C. albicans) effects. To develop fingerprints, thin layer chromatography (TLC) was carried out with at least one extract of each active plant. ResultsThirty-seven plant species belonging to 26 families used frequently in the CRF were categorised into twenty disease(s) and markedly high ICF values (0.5–1) were found. The FL of the 19 most important plant species ranged from 10% to 100%. Aglaia spectabilis, Actinodaphne obovata, Bischofia javanica, Gmelina arborea, Hodgsonia macrocarpa and Mesua ferrea were the most popular plant species with RPL values > 0.4. The most commonly treated diseases were skin infections, worm infections, diarrhoea, dysentery, common cold and throat infections, cough and respiratory problems, fever, malaria, rheumatism, pain, stomach ache and gastric problems. Among the taxonomic families, the most represented are Lauraceae (4 species); Meliaceae (3 species), Euphorbiaceae, Elaecarpoceae, Magnoliaceae, Malvaceae, Moraceae and Myrtaceae (2 species each). Of these, 35 plants (95%) with 91 of their extracts were found to be active against S. aureus (inhibition > 50%). Similarly, over half of the tested plants inhibited growth of E. coli (19 plants with 31 extracts) while 9 plants with 14 extracts were active against C. albicans. Moreover, one-third (12) of the plants showed anti-enteroviral activity. TLC analysis of the extracts indicates the presence of different phytochemical classes such as alkaloids, flavonoids, glycosides, terpenoids and saponins based on observing characteristic spots under visible or UV light (254 or 360 nm), with or without derivatisation. ConclusionsThirty-seven plants commonly used by the tribes of the CRF as anti-infective agents offer perspectives for further research, as the phytochemistry and phytopharmacology for most of these plants have not been published to date.

Ethnomedicinal and cultural practices of mammals and birds in the vicinity of river Chenab, Punjab-Pakistan

BackgroundAlthough, use of animal species in disease treatment and culture practices is as ancient as that of plant species; however ethnomedicinal uses and cultural values of animal species have rarely been reported. Present study is the first report on the medicinal uses of mammals and bird species in Pakistan.MethodsQuestionnaires and semi-structured interviews were applied to collect qualitative and quantitative data from local informants (N = 109). Relative frequency of mention (RFM), fidelity level (FL), relative popularity level (RPL), similarity index (SI) and rank order priority (ROP) indices were used to analyzed the data.ResultsOne hundred and eight species of animals, which include: 83% birds and 17% mammals were documented. In total 30 mammalian and 28 birds’ species were used to treat various diseases such as rheumatic disorders, skin infections and sexual weakness among several others. Fats, flesh, blood, milk and eggs were the most commonly utilized body parts. Bos taurus, Bubalus bubalis, Capra aegagrus hircus, Felis domesticus, Lepus nigricollis dayanus and Ovis aries (mammals) and Anas platyrhynchos domesticus, Columba livia, Coturnix coturnix, Gallus gallus and Passer domesticus (birds) were the highly utilized species. Medicinal and cultural uses of 30% mammals and 46% birds were reported for the first time, whereas 33% mammals and 79% birds depicted zero similarity with previous reports.ConclusionPresent study exhibits significant ethnozoological knowledge of local inhabitants and their strong association with animal species, which could be helpful in sustainable use of biodiversity of the region. Additionally, in vitro and in vivo evaluation of biological activities in the mammalian and birds’ species with maximum fidelity level and frequency of mention could be important to discover animal based novel drugs.Graphical Some commonly used mammals and birds species of the study area

An ethnobotanical survey of indigenous medicinal plants in Hafizabad district, Punjab-Pakistan.

Present paper offers considerable information on traditional uses of medicinal plants by the inhabitants of Hafizabad district, Punjab-Pakistan. This is the first quantitative ethnobotanical study from the area comprising popularity level of medicinal plant species intendedby using relative popularity level (RPL) and rank order priority (ROP) indices.Ethnobotanical data were collected by interviewing 166 local informants and 35 traditional health practioners (THPs) from different localities of Hafizabad district. Demographic features of informants; life form, part used, methods of preparation, modes of application and ethnomedicinal uses were documented. Ethnobotanical data were analyzed using quantitative tools, i.e. Relative frequency citation (RFC), use value (UV), informant consensus factor (ICF) fidelity level (FL), RPL and ROP indices. A total of 85 species belonging to 71 genera and 34 families were documented along with ethnomedicinal uses. Solanum surattense, Withania somnifera, Cyperus rotundus, Solanum nigrum and Melia azedarach were the most utilized medicinal plant species with highest used value. The reported ailments were classified into 11 disease categories based on ICF values and highest number of plant species was reported to treat dermatological and gastrointestinal disorders. Withania somnifera and Ranunculus sceleratus with maximum FL (100%), were used against gastrointestinal and urinary disorders, respectively. The RPL and ROP values were calculated to recognize the folk medicinal plant wealth; six out of 32 plant species (19%) were found popular, based on citation by more than half of the maximum number of informant viz. 26. Consequently, the ROP value for these species was more than 75. The comparative assessment with reported literature revealed 15% resemblance and 6% variation to previous data;however79% uses of the reported species were recorded for the first time. The diversity of medicinal plant species and associated traditional knowledge is significant in primary health care system. Medicinal plant species with high RPL values should be screened for comprehensive phytochemical and pharmacological studies. This could be useful in novel drug discovery and to validate the ethomendicinal knowledge.

Ethnopharmacological survey of medicinal plants used in Daraa-Tafilalet region (Province of Errachidia), Morocco

Ethnopharmacological relevanceWe carried out an ethnobotanical survey in Tafilalet region. This region is classified by the UNESCO as a reserve of biosphere and represents an important area with important knowledge of traditional medicine, especially the use of medicinal plants for human healthcare. Furthermore, the geographic location of this region makes this site a diverse and interesting resource of herbal biodiversity. The aim of the studyThe study aimed to collect information about medicinal plants used in Tafilalet region as well as the indigenous knowledge related to the use of this natural resource in healthcare by the local population in order to preserve and protect this invaluable inheritance from loss and overlook. We aimed also to compare taxa used by the indigenous people of Tafilalet for health-care purposes in comparison with other regions of Morocco as well as neighboring countries. Material and methodsThe total of informants interviewed in this study was 1616 (1500 were local inhabitants and 116 were herbalists). This enquiry was carried out through semi-structured and unstructured interviews and the sampling technique used was the stratified sample (9 stratums). Data obtained were analyzed calculating 6 indices: Use Value (UV), Family Use Value (FUV), Fidelity Level (FL), Rank Order Priority (ROP), Informant Consensus Factor (Fic) and Jaccard similarity Index (JI). Results194 species belonging to 69 families were inventoried in this survey and 17 species were cited for the first time in an ethnobotanical survey in Morocco. The highest value of UV was obtained for Rosmarinus officinalis L. (UV=0.24) and Liliaceae was the family frequently used by inhabitants of Tafilalet (FUV=0.106). In addition, the highest value of FL was recorded for Cistus salviifolius L. and Daphne gnidium L. with FL value of 100% for both species and Origanium vulgare L. had the highest ROP with a value of 53% while the highest value of FIC was mentioned for digestive system disorders (FIC=0.29). Concerning the level of similarity between our study and other regions of Morocco, the province of Tata seems to be the most similar to Tafilalet (JI=42.97), while M'sila (Algeria) was the most similar to Tafilalet among areas in neighboring countries (JI=13.00). ConclusionDespite the richness which characterizes Tafilalet regarding diversity and effectiveness of medicinal plants as well as the largest culture and knowledge related to the popular phytotherapy among local people in this region, several procedures must be realized to protect and to valorize this interesting inheritance.

Traditional Arabic Palestinian ethnoveterinary practices in animal health care: A field survey in the West Bank (Palestine)

BackgroundIn Palestine, medicinal plants have continued to play a vital role in fulfilling animal healthcare needs of rural communities. However, these valuable resources are being depleted mainly due to over-harvesting, inappropriate agricultural practices (e.g., over use of herbicides), agricultural expansion, and over-grazing. Therefore, immediate action is required to conserve these resources and document the associated knowledge. The purpose of this study was, thus, to document and analyze information associated with medicinal plants that are used in managing animal health problems in the West Bank, Palestine. Materials and methodsEthnobotanical data were collected from Apr 2012 to Feb 2014 mainly using semi-structured interviews with informants sampled using purposive sampling technique and through field observations. ResultsThe study revealed the use of 138 medicinal plant species in the West Bank for the treatment of several livestock diseases, of these 75 species representing 70 genera and 33 families were reported by 3 independent informants or above. Classification of the ethnoveterinary plant species cited by three informants or above used in a rank-order priority (ROP) based on their claimed relative healing potential has demonstrated that the following are the plants with the highest efficacy: Camellia sinenses, Teucrium capitatum, and Salvia fruticosa with ROPs of 97.1, 93.2, and 91.4, respectively, are used primarily to relieve gastric disorders. Gastrointestinal disorders is the disease group in the study area that scored the highest Informant consensus factor (ICF) value (0.90), followed by urinary, and reproductive disorders (0.89). ConclusionOur study provided evidence that medicinal plants are still playing important role in the management of livestock diseases, and showed that ethnoveterinary plants used in animal health care in Palestine have been also recorded in human Traditional Arabic Palestinian Herbal Medicine (TAPHM), and demonstrated a strong link between human and veterinary medical practices. This survey has identified a number of important medicinal plants used by the Palestinian farmers of the West Bank area for the treatment of various animal ailments. It provides a baseline for future phytochemical and pharmacological investigations into the beneficial medicinal properties of such plants.

Ethnobotany of Folk Medicinal Aquatic Plants in Jordan

ABSTRACT Eighty-seven species belonging to 59 genera and 33 plant families identified in the study area are presented. The three families with the most species represented were Labiatae (nine aquatic species), Compositae (seven species), and Salicaceae (seven species). The genera most represented were Mentha (six species), Polygonum (five species), and Salix (five species). Sixty-three folk-medicinal aquatic species (73.3%) had similar therapeutic uses in neighboring countries, while the 24 remaining species (26.7%) did not show therapeutic similarity with their use in other countries. Emerged species (plants rooted in soil under water but which emerge partially above the water's surface) were the most recorded, while amphibious, submerged, and floating species were the least recorded. The folk-medicinal importance of the recorded aquatic species were classified by rank-order priority (ROP). Twenty-one species (24%) had ROP values higher than 50, indicating the highest popularity level in folk-medicinal p...

Ethnobotanical survey in the Palestinian area: a classification of the healing potential of medicinal plants

An ethnobotanical survey was carried out in the West Bank to evaluate the relative efficacy of the plants used to treat skin diseases and prostate cancer. A total number of 102 informants, 30 years and older and either native born or had been living in the West Bank for more than 30 years, were interviewed using a previously prepared questionnaire. Of about 165 plant species mentioned by the informants, 63 (38.1%) were mentioned by three or more informants. On the basis of their primary uses, 21 of these plants were reported to relieve skin disorders, 17 for urinary system disorders, 16 for gastric disorders, nine for cancer and prostate disorders, eight for arthritis, five for respiratory problems, and five for other ailments. Indices on fidelity levels (FLs), relative popularity level (RPL), and rank-order priority (ROP) were calculated. Plants were classified in two groups: ‘popular’ (RPL=1) or ‘unpopular’ (RPL<1). The following plant species were classified as popular in this study: Teucrium polium, Matricaria aurea, Urtica pilulifera, Paronychia argentea, Petroselinum sativum, and Salvia fruticosa. The remaining 57 species were classified as ‘unpopular’. Fifty-nine plants were claimed to be effective against cancer and prostate disorders, which include Arum dioscorides, U. pilulifera, Allium sativum, Viscum cruciatum, and Allium cepa.

A preliminary classification of the healing potential of medicinal plants, based on a rational analysis of an ethnopharmacological field survey among Bedouins in the Negev Desert, Israel

In the course of an ethnopharmacological survey carried out among the Bedouins of the Negev desert, it was noticed that in addition to the use of modern medical services, medicinal plants were also being employed. We deemed it worthwhile, therefore, to investigate the current status of herbal medicine among the Negev Bedouins and to evaluate the relative efficiency of the plants used. To evaluate plant effectiveness by enquiries among patients once treated was found to be difficult and impractical. Hence, each interviewed informant was first requested to volunteer information on the plants and their uses. Next, to avoid the risk of memory failure, a list of 50 commonly used species was read out and the informant was asked to provide information on any that were familiar to him as medicinal herbs. Of 81 plant species mentioned by our 27 informants, 41 were named or recognized by more than 3. These species were arranged in accordance with the percentage of informants suggesting the same medicinal use for a given species as compared with the total number of informants reporting any sort of use for that plant. The obtained ratio was defined as the fidelity level (FL). The rank-order priority (ROP) of the plants was derived from these FL values. The relative popularity level (RPL) of the plants encountered was determined and plants were accordingly designated as “popular” or “unpopular”. FL values were further adjusted, according to RPL value. We found that the bark of Phagnalon rupestre is widely used to induce deliberate burns for the healing of various ailments (ROP = 100), while infusion of the shoots of Teucrium polium, or of Artemisia herba-alba is employed to a lesser degree (ROP = 66 and 56, respectively) to relieve stomach disorders. Because the latter two species show fairly high ROP and are seen to be directly curative, they merit further investigation. Additional findings and implications of our ethnopharmacological survey are duly discussed.
