Anti-inflammatory potential of zootherapeutics derived from animals used in Brazilian traditional medicine

CONTEXT: Animals are used for the treatment of diseases caused by inflammatory processes, although few studies evaluate their potential for these purposes. OBJECTIVES: To evaluate the anti-inflammatory potential of zootherapeutic products derived from vertebrates used in Brazilian traditional medicine. MATERIAL AND METHODS: The species analyzed were Tupinambis merianae, Iguana iguana, Crotalus durissus, Boa constrictor, and Euphractus sexcinctus. The methods used in anti-inflammatory assays were ear edema (topical) and paw (systemic). RESULTS: With regard to topical anti-inflammatory activity, the fat from T. merianae, C. durissus, I. iguana, B. constrictor, and E. sexcinctus reduced inflammation, while for systemic anti-inflammatory activity, only the fat and the skin of C. durissus, the skin of I. iguana and the fat from B. constrictor reduced inflammation. CONCLUSIONS: Studies should be conducted to evaluate the mechanisms of action for each product that demonstrated anti-inflammatory activity as well as against other inflammatory processes.
