ibogaine
Ibogaine is a psychoactive indole alkaloid derived from plants such as Tabernanthe iboga, characterized by hallucinogenic and oneirogenic effects. Traditionally used by Central African foragers, it has undergone controversial research for the treatment of substance use disorders. Ibogaine exhibits complex pharmacology by interacting with multiple neurotransmitter systems, notably affecting opioid, serotonin, sigma, and NMDA receptors, while its metabolite noribogaine primarily acts as a serotonin reuptake inhibitor and κ-opioid receptor agonist.

Silene undulata
species of plant

harmine
Harmine, also known as banisterine or telepathine, as well as 7-methoxyharman or 7-methoxy-1-methyl-β-carboline, is a β-carboline and a harmala alkaloid which has hallucinogenic effects and monoamine oxidase inhibitor (MAOI) activity. It occurs in a number of different plants, most notably Peganum harmala and Banisteriopsis caapi. Harmine reversibly inhibits monoamine oxidase A (MAO-A), an enzyme which breaks down monoamines, making it a reversible inhibitor of monoamine oxidase A (RIMA). Harmine does not inhibit MAO-B.

harmaline
Harmaline, also known as 7-methoxyharmalan or as 3,4-dihydro-7-methoxy-1-methyl-β-carboline, is a harmala alkaloid and β-carboline which has hallucinogenic effects and monoamine oxidase inhibitor (MAOI) activity. It is the partly hydrogenated form of harmine.
harmala alkaloid
group of chemical compounds
noribogaine
Noribogaine, also known as '''O-desmethylibogaine or 12-hydroxyibogamine', is the principal psychoactive metabolite of the oneirogen ibogaine. It is thought to be involved in the antiaddictive effects of ibogaine-containing plant extracts, such as Tabernanthe iboga''.
(+/-)-tetrahydroharmine
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.
6-MeO-THH
6-MeO-THH, also known as 6-methoxy-1,2,3,4-tetrahydroharman, is a β-carboline (or more specifically a pinoline) derivative and a structural isomer of tetrahydroharmine (7-MeO-THH). It is mentioned in Alexander Shulgin's book TiHKAL (Tryptamines I Have Known and Loved), stating that 6-MeO-THH is very similar to the other carbolines. The compound has been isolated from certain plants of the Virola family.
