bufotoxin, a moderately potent poison[1] secreted in the skin of many anuran amphibians, especially the typical toads[2] (genus Bufo). The milky fluid contains several identifiable components: bufagin, with effects on the heart similar to those of digitalis; bufotenine[3], a hallucinogen; and serotonin[4], a vasoconstrictor. The composition[5] of the poison varies with the species of toad[6]. Taken internally, the poison causes severe, even fatal reaction in many predators, but some animals (e.g., hognosed snakes) are not affected. The poison does not normally affect human skin[7], but it does irritate the eyes and mucous membranes.
