Indigenous knowledge of zootherapeutic use among the Biate tribe of Dima Hasao District, Assam, Northeastern India

摘要

Background The present study addresses the use of zootherapy in the traditional healthcare system of the Biate tribe of Dima Hasao district, Assam, India. It sought to identify the different species used for zootherapeutic use with the detailed methods of usages to create awareness and contribute to the conservation and sustainable utilization of the resources. Method 15 Biate villages within the district of Dima Hasao were surveyed through semi-structured questionnaires and informal interviews. Detailed information on the uses of each animal was recorded. Species were identified using standard literature. Fidelity level (FL) was calculated to demonstrate the percentage of respondents claiming the use of a certain animal for the same major purposes. Result The study documents 34 species for the treatment of about 34 different ailments. The largest number of species reported was mammals with17 species. Maximum number of species has been reported for the treatment of diabetes and its high fidelity levels warrants in-depth studies to establish its pharmacological activity. The usages documented herein are unique to the Biate tribe. Very often, these animals are hunted and sold openly at the local markets in the lure of quick money. A 300 gm live Gekko gecko may fetch a sum of 2,50,000 Indian Rupees (INR), and smoked meat of Hoolock hoolock cost approximately 250–300 INR per kg. Animals are also hunted for its hide. The unrestricted hunting of species like Capricornis sumatraensis has almost wiped out the population within the district. Some species are also reared as pets while some are used for display as a sign of expertise in hunting. The present study has documented the usage of at least 15 animals listed in the IUCN Red List. Conclusion The study illustrates the in-depth knowledge of the Biate tribe on zootherapy. Systematic investigation to identify the active ingredient may lead to the development of new drugs, which would prompt protection of these valuable resources.
