Ethnobotanical survey of medicinal plants used by various ethnic tribes of Mizoram, India.

Mizoram has a diverse range of ethnic and cultural groups, including the Lushai, Mara, Lai, Bawm, Hmar, Chakma, and Bru. Through practice and experience in their protracted battles with disease and the harsh natural environment, they have amassed rich folk medicine knowledge. The preservation of indigenous knowledge, identification of bioactive compounds, and the eventual discovery of novel medicinal plant species all depend on the documentation of the traditional uses of medicinal plants. Therefore, the present study was designed to document the ethnomedicinal knowledge related to the usage of medicinal plants in Mizoram, India. An ethnobotanical study of medicinal plants was carried out in 17 villages of 5 districts in Mizoram between September 2022 and January 2023. A total of 128 informants (77 males and 51 females) were interviewed. Information was gathered through field observations, group discussions, and semistructured interviews. The data were presented using descriptive statistics. To assess the importance of medicinal plant species, quantitative indices such as the informant consensus factor (ICF), fidelity level (FL), use value (UV), and cultural index (CI) was used. In our ethnobotanical investigation, 102 medicinal plant species from 95 genera and 58 families were recorded and documented. The majority of them (90 species) were obtained from wild habitats. The majority of the documented species were trees (48), followed by herbs (23 species) and shrubs (21 species). The most common method of preparation was decoction (67 species). Diabetes had the highest ICF value (0.81), followed by cancer, liver problems, and hypertension (0.8). The fidelity level (FL) of indigenous communities in the study area was evaluated to determine the dependability and consistency of herbal drug use. Indigenous knowledge and the variety of medicinal plant species that are used are of great values. The therapeutic applications of documented plants provide fundamental information for additional studies centered on pharmacological investigations and the preservation of the most significant species.
