, also known as '''d-lysergic acid amide''', '''LSA''', 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 '' (tlitliltzin), it is often stated that ergine and/or isoergine (its
Epimer ) is responsible for the hallucinogenic activity. In fact, the effects of synthetic ergine and isoergine, are not particularly hallucinogenic, see ''Mixing the Kykeon'' below for a summary of human trials, and Chapter 17 and entry #26 of
TiHKAL for further discussion. Whether or not these compounds account for the hallucinogenic effects of the seeds remains unclear. Ergine is a
DEA schedule III drug in the
United States .
