LSA, also known as d-lysergic acid amide, d-lysergamide, ergine, and LA-111, is an alkaloid of the ergoline family that occurs in various species of vines of the Convolvulaceae and some species of fungi. As the dominant alkaloid in the hallucinogenic seeds of Rivea corymbosa (ololiuhqui), Argyreia nervosa (Hawaiian baby woodrose) and Ipomoea violacea (morning glories, tlitliltzin), it is often stated that ergine and/or isoergine (its epimer) is responsible for the psychedelic activity. In fact, the effects of synthetic LSA and iso-LSA are not particularly psychedelic, see Mixing the Kykeon below for a summary of human trials, and Chapter 17 and entry #26 of Ti HKAL for further discussion.
