Ethnomedicinal Study of Medicinal Plants Used by Mizo Tribes in Champhai District of Mizoram, India.
Abstract Background Medicinal plants have been used countless times for curing diseases mainly in developing countries. They are easily available with little to no side effects when compared to modern medicine. This manuscript encompasses information on ethnomedicinal plants in Champhai district, located in the North East Region (NER) of India. The region lies within Indo-Burma biodiversity hotspot. This study will be the first quantitative report on the ethnomedicinal plants used by the local tribes of this region. Knowledge of medicinal plants is mostly acquired by word of mouth and the knowledge is dying among the local youths with the prevalence of modern medicine. Hence, there is urgency in deciphering and recording such information. Methods Information was gathered through interviews with 200 informants across 15 villages of the Champhai District. From the data obtained, we calculated the Used Report (UR), Frequency of Citation (FC) and Informant Consensus Factor (Fic) for all the plant species. Secondary data was obtained from scientific databases such as Pubmed, Sci Finder and Science Direct. The scientific name of the plants were matched and arranged in consultation with the working list of all plant species (http://www.theplantlist.org ). Results 93 plant species from 53 families were recorded. The most common families are Euphorbiaceae and Asteraceae with six and five species representatives respectively. Leaves were the most frequently used part of a plant and were usually used in the form of decoction. The plant species with the highest used report (UR) were Curcuma longa L. (136 FC) and Flueggea virosa (126 FC). The main illness categories as per Frequency of citation were Muscle/Bone Problem (0.962 Fic), Gastro-intestinal Disease (0.956 Fic) and Skin Care (0.953 Fic). Conclusion The people of Mizoram living in the Champhai district have an immense knowledge of ethnomedicinal plants. There are no new adverse effects recorded. We observed that there is a scope of scientific validation of 10 plant species for their pharmacological activity and 13 species for the phytochemical characterization or isolation of the phytochemicals. This might pave the path for developing a scientifically validated botanical or lead to semisyntheic derivatives intended for modern medicine.
