The present study was an attempt to record the quantitative medicinal plant use data by four indigenous tribes– Kattunaikkan, Mullakuruman, Adiyan and Kuruchiyar- of Wayanad District, Kerala, India. Quantitative indices such as Use value (UV), Family use value (FUV), Shannon Wienner index, Simpson index and Berger Parker index were used to understand the preferences and consensus existing among the informants regarding medicinal plant use. A total of 565 user reports were collected from the fifteen informants belonging to the four socio-cultural groups during the study period. Mention of each use of a species with respect to a disease was treated as a separate event and considered as a user report. Among the 63 families from which the informants cited 565 uses, eighteen families which scored a FUV more than 1 and 42 species which recorded a UV more than 0.25 were enumerated in this study. Shannon Wienner index, Simpson index and Berger Parker index were also calculated.
