Ethnozoological Study of Traditional Medicinal Animal Parts and Products Used among Indigenous People of Assosa District, Benishangul-Gumuz, Western Ethiopia

Traditional medicine is a global practice and depends on locally available natural resources and indigenous knowledge. Animals and their products have been used in the preparation of traditional remedies in various cultures since time immemorial. This study aimed to identify and document traditional medicinal sources from animals and associated indigenous knowledge in Assosa Districts, Benshangul Gumuz region, western Ethiopia, from September 2019 to July 2020 to ensure sustainable utilization of natural resources and biodiversity. A cross-sectional survey design was used to collect ethnozoological information with regard to animals used for medicinal purposes, parts used, ingredients added, ailments treated, method of preparation, mode of administration, dosage and duration of treatment, and the mechanisms of knowledge transfer. A total of 38 animal species were used as medicine to treat over 35 different kinds of human diseases including anatomical, physiological, psychological, and spiritual ailments and veterinary treatment. Over 15 animal species were found to score fidelity level (FL) more than 50%, of which the skin of Crocuta crocuta used for the treatment of evil eye had the highest FL (n = 35, 92.1%), followed by the blood of Sus scrofa domestica for treatment of stomach illness (n = 32, FL∼84.2%), the milk of Equus asinus to treat cough and eye disease (n = 28, Fl∼73.7%). The study area harbors diverse medicinal animals that represent key medical alternatives for local communities. The documentation of this indigenous knowledge of animal-derived medicine and the practice helps in developing strategies for conservations of biological diversities.
