Tetrahydroharmine Benefits and Uses


Tetrahydroharmine (THH) is a compound found in the plant Banisteriopsis caapi –one of the key ingredients of Ayahuasca. Our Tetrahydroharmine is racemic (±)-Tetrahydroharmine, consisting of both the (+) and (-) optical isomers. It is known that Tetrahydroharmine is a mild serotonin reuptake inhibitor - and additionally it is speculated that one isomer of our (±)-THH, may weakly and reversibly inhibit the activity of an enzyme called monoamine oxidase A (MAO-A), which regulates the functioning of important monoamine neurotransmitters - including dopamine and serotonin. Dopamine and serotonin play important roles in regulating motivation, perception, and overall mood. The net effect of increasing these chemical messengers is said to be an overall improvement in mood, cognitive clarity and increased sense of calm focus.


Today, THH can be used as a nootropic and neuroprotective compound that may offer additional beneficial effects including stress relief and mood improvement. A scientific study published in the reknowned journal, Nature, has also recently uncovered a very unique property of THH and related harmala alkaloids in enabling adult neurogenesis! THH is also used synergistically with other MAO substrate ingredients that have cognitive enhancing and mood enhancing effects, including natural indole and phenylethylamine derivatives.




Tetrahydroharmine is known by a number of alternative names including:










Scientific Consensus:


Tetrahydroharmine (THH) is a compound that regulates key neurotransmitters namely dopamine and serotonin. It is taken primarily for its nootropic, neuroprotective and neurogenesis promoting effects as well as ability to improvie mood, cognitive function and reduce feelings of stress.


Further clinical research is required to fully support the safety, dosage and potential benefits of THH.
