“…A total of 70 informants including seven traditional healers were interviewed: 43 (61.4%) men and 27 (38.6%) women (P = 0.064), ranging in age between 30 and 70 years (mean age = 50; median age = 53) ( Table 4). In general, interest and therefore knowledge in medicinal plants generally increases with age as shown in a similar study [42]. Respondents originated from seven out of the thirteen provinces of the country, including Nouakchott, and belong to the main ethnolinguistic groups of Mauritania: Moorish of Arab descent (87.1%) and black Africans (12.9%).…”

Phytochemicals and antioxidant activity of fruits of 30 B. aegyptiaca trees naturally growing in the hyper-arid and arid zones in Mauritania were evaluated by following standard procedures. Ethnobotanical uses of fruit pulps and kernel were assessed using a structured questionnaire. Balanites aegyptiaca fruit pulp is a good source of sugars (33 g/100 g dry matter (DM)), polyphenols (264 mg GAE/100 g DM) and flavonoids (34.2 mg/100 g DM) with an average antioxidant activity of 519 µmol TEAC/100 g DM. The fruit kernel is rich in lipids (46.2 g/100 g DM) and proteins (29.5 g/100 g DM). Fruits from the hyper-arid zone exhibited high level of polyphenols, antioxidant activity and soluble tannins. Almost all of the informants (97.14%) reported the use of fruit pulp in folk medicine to treat diabetes, while 72.86% reported using the fruit pulp to treat hypertension. Kernel oil is mainly employed as ointments in the treatment of paronychia (57.14%) and dermal infections (35.71%). The predominant methods for preparing/administering fruit pulp/Kernel were maceration (58.8%), sucking fruit pulp (25.7%) and decoction (24.2%). Balanites aegyptiaca fruit contain both nutritional and health-promoting phytochemicals that could be of interest in the development of strategies for sustainable use of this neglected indigenous fruit tree.

“…In addition to its potential to discover new therapies [137][138][139], indigenous knowledge of medicinal plants is known for its socio-economic, conservative and cultural values [136]. However, the indigenous knowledge on medicinal plants varies with socio-economic, demographic, historical and ecological status [140,141]. Using a certain quantitative index, indigenous knowledge on medicinal plants in one area can be compared with others.…”

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 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 three focus group discussions and 47 key informant interviews using semi-structured questionnaires. 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 diseases categories.
