"Animals in Traditional Folk Medicine" offers a comprehensive analysis of the role of animals in traditional folk medicine and their significance for conservation. The book highlights how various cultures have utilized animal products in their healing practices over centuries and the challenges that arise from the sustainable use of these resources. Given that traditional medicine serves as a primary health source for a large portion of the global population, the need to understand the connections between traditional medicine and biodiversity becomes increasingly urgent. Authors Rômulo Romeu Nóbrega Alves and Ierecê Lucena Rosa discuss the impacts of animal use on biodiversity and encourage dialogue on sustainable practices in traditional remedies. This scholarly work is a valuable resource for anyone engaged with the intersections of medicine, natural sciences, and conservation.
