„I. corymbosa (Rivea corymbosa) is known by psychomimetic active principles of its seeds, the ancient Aztec drug „ololiuqui“. In the seeds of this species were found alkaloids of the ergot type, such as, D-lysergic acid amide or LSA, also called ergine, as the major component in ololiuqui seeds as well as, the following minor alkaloids: chanoclavine I, elymoclavine, D-isolysergic acid amide also called erginine or isoergine and lysergol. LSA or ergine is a close analogue of best-know syntetic LSD (lysergic acid diethylamide). Hallucinogenic activity of LSA occurs with 2-5 mg, while LSD occurs at the microgram level. Elymoclavine, erginine and lysergol are also known to be psychoactive in humans.“
