Family: Tryptamines
LSA ( d-lysergic acid amide, d-lysergamide, or ergine) is a psychoactive alkaloid found in various vines of the Convolvulaceae family and some species of fungi. It can also be found in the seeds of Turbina corymbosa (ololiuhqui), Argyreia nervosa (Hawaiian baby woodrose), and Ipomoea tricolor (morning glories, tlitliltzin). Reports indicate traditional use of LSA- containing seeds as a sacrament by Mexican Native Americans and the Zapotecs. LSA is also a precursor of LSD.
It is usually taken either in the form of the seeds or extracted and ingested orally. LSA has strong vaso-constrictive properties and can be dangerous when taken in high doses.
