Harmaline is a fluorescent psychoactive indole alkaloid from the group of harmala alkaloids and beta-carbolines. It is the reduced hydrogenated form of harmine.
Occurrence in nature
Various plants contain harmaline including Banisteriopsis caapi (a jungle vine) and Peganum harmala (Syrian Rue) as well as the hallucinogenic drink ayahuasca, which is traditionally brewed using Banisteriopsis caapi. Also passionflower (Passiflora incarnata) and tobacco.[2]
Effects
Harmaline is a central nervous system stimulant and a "reversible inhibitor of MAO-A (RIMA)."[3] It being a reversible MAO-A inhibitor means that it competes with tyramine for binding to MAO-A, so foods containing some tyramine can be safely consumed (wine and aged cheese should probably be avoided for 12 hours prior to consuming harmaline containing plants). The reversibility means that, instead of binding permanently to MAO-A for weeks until the body replaces the MAO-A enzyme molecules, harmaline binds only transiently, so tyramine can be metabolized as well by competing with harmaline for the binding site on the enzyme.[4] This means that the risk of a hypertensive crisis, a dangerous high blood pressure crisis from eating tyramine-rich foods such as cheese, is potentially lower with harmaline than with non-reversible MAOI's, especially after 24 hours following ingestion.
Harmaline is shown to act as an acetylcholinesterase inhibitor.[5]Harmaline also stimulates striatal dopamine release in rat at very high dose levels.[6]
Depending upon the dosage, harmaline induces temporary oneirophrenia and ataxia. Harmaline, on the higher end of its safe dosage range, has hallucinogenic properties, but it differentiates itself significantly from the "classical" hallucinogens in its pharmacology. Since harmaline is a reversible monoamine oxidase inhibitor, it could increase the effect of some drugs problematically. Harmaline causes no known physical or psychological dependence.
United States Patent Number 5591738 describes a method for treating various chemical dependencies via the administration of harmaline and or other beta-carbolines.[7]
Claudio Naranjo has studied potential applications of harmal alkaloids in psychotherapy.
Harmaline has also been shown to induce "vasorelaxant effects" in "isolated rat aorta."[8]
Harmaline has both protective and toxic effects on neurons.[7]
Harmaline is known to act as a histamine N-methyltransferase inhibitor.
History
In the year 1841 harmaline was isolated from Peganum harmala by Goegel.[7] It was first synthesized in 1930 by Hasenfratz.[7]
