Abstract
Wade  Davis's study of Haitian “zombification” in the 1980s was a landmark in  ethnobiological research. His research was an attempt to trace the  origins of reports of “undead” Haitians, focusing on the preparation of  the zombification poison. Starting with this influential  ethnopharmacological research, this study examines advances in the  pharmacology of natural products, focusing especially on those of  animal-derived products. Ethnopharmacological, pharmacological, and  chemical aspects are considered. We also update information on the  animal species that reportedly constitute the zombie poison. Several  components of the zombie powder are not unique to Haiti and are used as  remedies in traditional medicine worldwide. This paper emphasizes the  medicinal potential of products from zootherapy. These biological  products are promising sources for the development of new drugs.
