The study deals with quantitative ethno-medicinal study with the aim of documenting the indigenous knowledge and practices of using plants for therapy of gastrointestinal disease among the Adi tribe of Eastern Himalaya. Ethno-medicinal data were documented from 120 informants by using semi-structured questionnaires. Documented data were evaluated using the quantitative ethno-botanical indices of relative frequency of citation (RFC) and percentage of respondents having knowledge (PRK). A total of 54 plant species belonging to 36 taxonomic families were recorded within the study area. Maximum contribution was reported from herbs (45%), subsequently followed by shrubs (33%), tree (15%) and climbers (7%). Among the different plant parts used, the leaves (41%) were most frequently used for the preparation of medicine. The paste (30%) was the most commonly followed mode of utilization, followed by decoction (27%). The study also revealed the potentiality of medicinal plants in treating about 15 different types of GI disorders. Plant species Clerodendrum colebrookianum reported with a high relative frequency of citation (RFC= 0.78) and percentage of respondents having knowledge (PRK= 77.50%), followed by Pouzolzia hirta (RFC = 0.74, PRK= 74.17%). Indigenous Adi tribe of this region has demonstrated remarkable knowledge on the medicinal plants used against GI disorders.
