Ethnobotanical survey of plants traditionally used against hematophagous invertebrates by ethnic groups in the mountainous area of Xishuangbanna, Southwest China

Hematophagous invertebrates such as mosquitoes,leeches,mites,ticks,lice and bugs cause various problems for humans.Considering reports on insecticide resistance and requirements for improved environmental and toxicological profiles,there is a continuing need to discover and develop new insecticides and repellents.Ethnobotanical surveys of traditional plant-based repellents provide a direct method of identifying plants for potential use.During five field surveys in Bulang,Jinuo and Lahu villages between August 2018 and July 2019,semi-structured interviews were conducted with 237 informants(151 male,86 female;mean age 63).Frequency of citation,use value,informant consensus factor and Jaccard index were employed to statistically analyze the collected data.A total of 709 use reports relating to 32 plant species and 71 remedies were collected.Similarities and differences between the three groups,as well as the Dai and Hani of Xishuangbanna,who were studied earlier,were shown through network analysis.These five ethnic groups living in the same area have a common understanding of traditional botanical knowledge against hematophagous invertebrates,but each group also possesses unique knowledge.Recording and protecting this traditional knowledge is potentially useful for protecting this cultural diversity and related biodiversity and can also have important practical applications.In this study,traditional knowledge provided us with many new potential plants for follow-up research for the development of new insecticides and repellents,among which Artemisia indica,Nicotiana tabacum and Clausena excavata are the most promising.

Medicinal and Aromatic Plants Used in Traditional Treatment of the Oral Pathology:The Ethnobotanical Survey in the Economic Capital Casablanca,Morocco(North Africa)

In order to identify the medicinal and aromatic plants most requested for the treatment of the most common oral pathology,an ethnobotanical survey was carried out in the economic capital Casablanca,Morocco.The data basis was obtained draw selected traditional herbalists based on the semi-structured questionnaire.Quantitative indices such as use value(UV),family UV(FUV),fidelity level and informant consensus factor(ICF)were intended to evaluate the importance of plant species.A total of 46 plants species belonging to 22 families that were used.Juglandaceae family showed the highest significance(FUV=0.75).We identified 40 species used for gum disease(gingivitis,periodontal abscess),15 for dental pain(toothache,tooth sensitivity),14 for halitosis,12 for oral ulcers(aphtous,mouth ulcers and herpes),3 for dental stain(teeth cleaning,sparkling and bleaching)and only 2 for tooth decay.The used plants are mainly prepared as decoction(80.4%).Syzygium aromaticum(UV=0.94)was the specie most commonly prescribed by local herbalists.The higher ICF(0.75)was registered for the use gum disease.

Ethnobotanical Survey of Appetite Suppressant Plants Used in Hauts-Bassins Areas of Burkina Faso

This study aimed to list the medicinal plants used as an appetite suppressant in Hauts-Bassins areas of Burkina Faso. An ethnobotanical survey was undertaken from September to November 2021 using a semi-structured questionnaire. To determine well-known families and species, some indices such as Family Importance Value (FIV) and Relative Frequency of Citation (RFC) were calculated respectively. Sixty-seven traditional healers (41 men and 26 women) have been interviewed. The age group from 41 to 60 years old was more represented (47.76%). Fifty-eight (58) plant species belonging to 29 families and 53 genera were recorded to have appetite suppressant properties. Fabaceae family (25%) was the most mentioned followed by Combretaceae (12%). The most mentioned species were Guierasenegalensis (7.64%), Parkiabiglobosa (6.18%), Annona senegalensis and Gardenia erubescens (5.35% for both). Leaves and fruits had the highest frequencies of use with 41% and 25% respectively. The decoction (49.62%) was the main preparation method. The oral route was the only mode of drug administration. These results would contribute to strengthening the database on the medicinal plants used as an appetite suppressant by the traditional healers in Burkina Faso.

Erratum to “Census Ethnobotanical Study of Some Plants Used in Traditional Medicine in the City of Meknes” [American Journal of Plant Sciences 5 (2014) 2480-2496]

An ethnobotanical survey was conducted in the city of Meknès over a period of two years, from 2009 to 2011 with 1000 people (615 women, 385 men). Through the questionnaire, schedules were established to collect information on the use of therapeutic medicinal plants by the local population. This research has focused primarily on the general population, herbalists and healers. The present investigation has enumerated 194 species distributed in 165 genera and 72 families. The most represented families are Lamiaceae (18%), the Aseraceae, (17%), the Apiaceae (14%) and the Fabaceae (10%). The results of the survey show that 54% of individuals use both herbal medicine and modern medicine, 26% of individuals use herbs and 20% use modern medicine. We are interested in the use of plants in different ages and sexes. We report that 31% of the population is aged between 51 and 60 years, 29% between 41 and 50 years, 23% between 31 and 40 years, 10% between 21 and 30 years, 3% less than 20 years and 4 % > 60 years. We note the predominance of women over men. Women use up to 61% against 39% of men. The analysis of our results shows that herbal medicine takes a place in the self-medication of the population studied. However, we emphasize an important point: Ignorance of toxic plants, in fact, only 19% of the target population recognizes these plants.

Ethno-medicinal plants used by Bengali communities in Tripura, northeast India

Northeastern India has high medicinal plant diversity due to variance in topography and physiognomy. We documented the uses of various medicinal plants by the Bengali people of West district and South district of Tripura state for their own health care as well as for domesti-cated animals. Based on semi structured interviews, group discussions and information from local informants, a total of 93 species of medicinal plants of 52 families and 83 genera were documented. These plants were used to treat more than 55 different human diseases and 6 diseases of livestock. Sixty-eight plant species were used singly and the rest were used in combination with other species for therapeutic formulations of various diseases. Leaves of plants were most often used for most of the ethnobotanical preparations. Maximum consensus value of 96% was recorded for Chromolaena odorata （L.） King ＆amp;H. Rob., and the mini-mum was 15%for Bambusa balcooa Robx. Of the 93 plant species, 75 species showed pharmacological properties. Prospects for augmenting existing knowledge and enhancing the use of traditional medicinal plants are discussed.

Knowledge and Traditional Uses of Some Aromatic and Cosmetic Plants Species in the Western Highlands of Cameroon

The valorisation of plant genetic resources following the Access and Benefit Sharing (ABS) process of the Nagoya Protocol requires the mastery of traditional knowledge associated with their uses by local populations. The objectives of this study were to survey the aromatic or cosmetics plants species used by the populations and to collect information on the knowledge associated with their uses in the Western highlands of Cameroon. Ethnobotanical surveys were carried out in 12 localities, where 251 individuals, including 206 men and 45 women, whose ages ranged from 25 to 81 years were interviewed. Information on each of the plant species mentioned and their different uses were recorded. A total of 103 species in 81 genera and 46 families were cited for aromatic or cosmetic uses, of which the most represented were the Lamiaceae (18 species), Asteraceae, and Zingiberaceae (7 species each). The identified plants were grouped into four categories of use: medicinal (56.31%), cosmetic (10.68%), food (6.80%), and cultural (1.94%). Most of the species surveyed were herbaceous (66%) with leaves being the most used part. The diversity index values of the respondents showed 10 species that were very well known and used by the populations: Eryngium foetidum, Chenopodium ambrosioides, Ocimum gratissimum, Piper umbellatum, Cinnamomum zeylanicum, Aframomum melegueta, Citrus limon, Costus afer, Cyperus rotundus, and Mondia whitei. These species were mainly used for: cough, spiritual protection, sexual weakness, cysts, diabetes, prostate, rheumatism, filaria, insomnia, female sterility, jaundice, scabies, haemorrhoids, high blood pressure and asthma. The results obtained constitute a valuable source of information that can contribute to the establishment of value chains allowing the effective valorisation of species following the ABS process.
