The species Jatropha gossypiifolia L. (Euphorbiaceae), popularly known as bellyache bush, among several other names, is an important example of the tenuous threshold that separates the therapeutic from the toxic effect. Although traditionally known as a toxic plant, it has been used in folk medicine. Some of its effects have been proved by experimental studies as antimicrobial, antineoplastic, healing and hypotensive, likely explained by the presence of substances such as alkaloids, terpenoids, flavonoids, lignans and tannins. This review deals with important aspects, focusing on the chronic toxicity of this species, in order to serve as an information source for those interested in evaluating the risk-benefit ratio of the therapeutic use of Jatropha gossypiifolia L.
