aroused in a sexual way. Aphrodisiacs can be categorized according to their mode of action into three groups:
substances that increase libido (i.e., sexual desire, arousal), substances that increase sexual potency (i.e., effec-
tiveness of erection) and substances that increase sexual pleasure. Some well-known aphrodisiacs are Tribulus
terrestris, Withania somnifera, Eurycoma longifolia, Avena sativa, Ginko biloba, and Psoralea coryifolia.
Ethnobotanical surveys have indicated a large number of plants as aphrodisiacs. The paper reviews the recent
scientific validation on traditionally used herbal plants as aphrodisiac herbs for the management of sexual dis-
order erectile dysfunction.
Keywords: aphrodisiacs, herbal plants, erectile dysfunction
