Tetrahidroharmina

Tetrahydroharmine (THH), also known as 7-methoxy-1,2,3,4-tetrahydroharman (7-MeO-THH), is a fluorescent indole alkaloid and β-carboline that occurs in the tropical liana species Banisteriopsis caapi. It is an oneirogenic hallucinogen similarly to harmaline. Conversely however, in contrast to other harmala alkaloids, it is very weak as a monoamine oxidase inhibitor (MAOI).
