An indole alkaloid, sometimes used as a recreational drug, discovered in 1847, found in the seeds of the plants Peganum harmala (Syrian rue), native to southern Europe and Asia Minor, and also in Zygophyllum fabago and Passiflora incarnata (the passion flower). Native South Americans were the first to prepare from it the hallucinogenic drink yagé. It is a brief monoamine oxidase inhibitor that also acts as a serotonin antagonist and hallucinogen. Formula: C13H12N2O. [From Latin harmala wild rue, from Arabic harmil + -ine indicating an organic compound]
