“…Nonetheless, such hypothesis-driven ethnobotanical studies are scant particularly in plant-rich countries with broad traditional medicinal knowledge like Nepal [ 6 , 19 – 23 ]. Recent studies still focus on medicinal plant diversity, their use patterns and conservation issues [ 24 – 26 ]. In this study, we tested the non-random medicinal plant selection hypothesis through using national- and district-level datasets.…”

Background There are handful hypothesis-driven ethnobotanical studies in Nepal. In this study, we tested the non-random medicinal plant selection hypothesis using national- and community-level datasets through three different types of regression: linear model with raw data, linear model with log-transformed data and negative binomial model. Methods For each of these model, we identified over-utilized families as those with highest positive Studentized residuals and underutilized families with highest negative Studentized residuals. The national-level data were collected from online databases and available literature while the community-level data were collected from Baitadi and Darchula districts. Results Both dataset showed larger variance (national dataset mean 6.51 < variance 156.31, community dataset mean 1.16 < variance 2.38). All three types of regression were important to determine the medicinal plant species selection and use differences among the total plant families, although negative binomial regression was most useful. The negative binomial showed a positive nonlinear relationship between total plant family size and number of medicinal species per family for the national dataset (β1 = 0.0160 ± 0.0009, Z1 = 16.59, p < 0.00001, AIC1 = 1181), and with similar slope and stronger performance for the community dataset (β2 = 0.1747 ± 0.0199, Z2 = 8.76, p < 0.00001, AIC2 = 270.78). Moraceae and Euphorbiaceae were found over-utilized while Rosaceae, Cyperaceae and Caryophyllaceae were recorded as underutilized. Conclusions As our datasets showed larger variance, negative binomial regression was found the most useful for testing non-random medicinal plant selection hypothesis. The predictions made by non-random selection of medicinal plants hypothesis holds true for community-level studies. The identification of over-utilized families is the first step toward sustainable conservation of plant resources and it provides a baseline for pharmacological research that might be leading to drug discovery.

“…These plants have high antimicrobial, antiseptic and anti-inflammatory properties, and were being used for similar therapeutic purposes in different localities [20,21,87,92,134]. The high use value of these species may be attributed to easy availability, common distribution, and widespread information about their therapeutic uses within the community [93]. The RFC of the reported medicinal plant species was 21% on average and only 16.4% species (23 species) have over 25 citations.…”

Background: Chyangthapu-Phalaicha located in the northeastern Panchthar District, is a biodiversity hotspot in the Eastern Himalaya. The area is dominated by the Kirat indigenous community. The present study was conducted to document the knowledge of the ethnomedicinal uses and practices that exist in the area before the associated socio-cultural knowledge on biological diversity is lost. Methods: Ethnomedicinal data were collected through semi-structured questionnaires. Stakeholders meetings were organized for assessing the conservation issues in the sub-corridor. The importance of medicinal plant species was assessed using quantitative indices such as informant consensus factor, relative frequency of citation, relative importance, fidelity level and Rahman’s similarity index. Results: Altogether, 140 medicinal plant species from 68 families and 127 genera were reported, which were used to treat 12 health disorders categories. The dominant families were Asteraceae and Fabaceae which contributed eight species each. Fifty-five percent of the total medicinal plant species comprised of herbs. The most frequently used plant parts were underground parts (33%) and leaf (15%). The most common remedies preparation method was extract. Oral administration was the most common therapeutic mode (60%). Maximum informant consensus factor (0.96) was calculated for gastrointestinal disorders. The highest relative frequency of citation and fidelity level was observed for Swertia chirayita (0.83 and 100% respectively). Artemisia dubia depicted the highest relative importance (91.67). A thorough review of previous literature and analysis of field data revealed new therapeutic use reports for 41 ailments associated with 52 plant species. The Rahman similarity index was high with the studies in neighbouring areas, while it was low with the geographically distant studies. Conclusions: The ethnomedicinal study of the Chyangthapu-Phalaicha biological sub-corridor in the Kangchenjunga Landscape indicates that the area supports significant medicinal plants and associated traditional knowledge. The varied use of reported medicinal plants in the area indicates the need for their domestication, processing and phytochemical investigation, especially for those with high ethnobotanical indices.

“…The documentation of ethnobotanical knowledge helps in the preservation of indigenous culture and contribute to the conservation and management of plant diversity that benefits the local communities (Luitel et al, 2014). Over 2,500 plant species are medicinal in Nepal (Ghimire, 2008;Bhatt & Kunwar, 2020) which are used in the traditional systems of medicine. The uses are associated with diverse ethnic groups of the country residing in diverse geographical ranges, and the knowledge is transferred orally through grenrations (Adhikari et al, 2019).…”

This study was aimed to document medicinal plant species, their utilization and methods to treat common ailments by traditional healers in Churiya region of Ilam district, eastern Nepal. This study would contribute positively to the field of biodiversity conservation, phytochemistry and ethnopharmacology. Ethnobotanical informations were collected in 2016 based on semi-structured questionnaire with key informant interview. Data were evaluated and expressed in terms of number and percentage. A total of 116 medicinal plants belonging to 61 families were reported to treat 76 different ailments categorized into 18 groups. The highest numbers of plants were used to treat digestive system disorders. The most medicines were prepared as the form of paste from leaves or tender shoots and administrated orally. Of the documented plants, 5 species were reported with novel uses and 7 were newly reported as ethnomedicinal plants in Nepal. Besides medicine, 111 species were utilized additionally for food, fodder, socio-cultural events and environmental use. People of the area less frequently use traditional herbal therapies. Due to lack of proper collection, conservation and cultivation practices, some plant species are at risk of extinction. Thus, sustainable harvesting and access to benefit sharing help to improve livelihood and conserve biodiversity.
