Lysergic acid hydroxyethylamide  -Lysergic acid α-hydroxyethylamide (LSH, LAH), also known as -lysergic acid methyl carbinolamide, is an alkaloid of the ergoline family, believed to be present in small amounts in various species in the "Convolvulaceae" (morning glory) (LSA), as well as some species of fungi. The structure is similar to LSD, with the N,N- diethylamide group replaced by an "N"- (1- hydroxyethyl)amide in -lysergic acid α-hydroxyethylamide. One of the alkaloids in the seeds of "Rivea corymbosa" (Ololiuhqui), "Argyreia nervosa" (Hawaiian Baby Woodrose), and "Ipomoea violacea" (Tlitliltzin) are ergine (LSA) and isoergine (its epimer). The human activity of -lysergic acid α-hydroxyethylamide is unknown.  -lysergic acid α-hydroxyethylamide is unscheduled and uncontrolled in the United States, but possession and sales of it for human consumption could potentially be prosecuted under the Federal Analog Act because of its structural similarities to LSD.
