Ethnopharmacological relevance The goal of this study was to conduct an ethnobotanical survey of medicinal species from the carrasco vegetation of the Araripe National Forest, state of Ceará, Brazil, as well as determining species with bioprospecting potential Materials and methods The ethnobotanical data were collected through semi-structured interviews and a free list. The relative importance of the plants cited was assessed, as well as species that stood out with respect to bodily systems, on the basis of informant consensus. Results A total of 32 species belonging to 29 genera and 20 families were recorded. Of this total, six species (19%) showed great versatility regarding their uses in regard to up to seven bodily systems. The therapeutic indications were grouped into 14 categories of bodily systems. Circulatory and genitourinary disorders, endocrine, nutritional and metabolic diseases, and undefined pain or disease showed the greatest consensus between informants. Conclusions Ximenia americana , Himathantus drasticus , Stryphnodndron rotundifolium , Bowdichia virgilioides , and Hymenaea courbaril were the species warranting more in-depth study, on the basis of versatility and informant consensus on the uses of the species.
