Tetrahydroharmine (THH) is a compound found in the plant Banisteriopsis caapi, traditionally used in spiritual journeys by the indigenous shamans of South America as part of the plant infusion Ayahuasca. Modern science has further corroborated the unique nootropic, antioxidant, neuroprotective, neurogenesis-, cognition-, and mood-enhancing properties of THH, which has the molecular formula C13H16N2O and a molecular mass of 216.28 g/mol.

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.

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 renowned 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:

  • (R)-Tetrahydroharmine
  • THH
  • UNII-AF812R7053

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 improve mood, cognitive function and reduce feelings of stress. Further clinical research is required to fully support the safety, dosage and potential benefits of THH.

(±)-Tetrahydroharmine (THH) Powder

I quit energy drinks for health reasons and felt like I was sleep walking through my life. My daughter bought me THH and I can think clearly again. No jitters or notice it too much other than I feel awake and alert. No fog.

(±)-Tetrahydroharmine (THH) Powder

I started out with 15mg sublingual and had a mild but nice mellow energetic buzz for about 4 hours. Next I’ll try 25mg and see how that works out. I feel a gentle sense of calm and a slight mood boost when I take this thh. Quality product!

The best ROA I've found for THH is to hold it under the tongue for at least 5 minutes. Additionally, it helps to suck on a vitamin C drop while holding it under the tongue. Around 5 minutes one can notice some mood enhancement, but that's only the start and it continues building upwards of 20+ minutes. Later on, feelings of warmth enveloping the body and tingling in extremities can be felt.

As a Nootropic Compound, take 1 serving up to 2 times per day. Please start with the lowest suggested single serving quantity to assess response.

Scientifically Tailored Ingredients

Tetrahydroharmine (THH) is one of a family of β-carboline (indole-related) harmala alkaloids, found in the Banisteriopsis caapi (yagé, or ayahuasca) vine and related species, as well as in Peganum harmala (which lends these alkaloids their “harmala alkaloid” nomenclature).

Scientific research has revealed that (±)-Tetrahydroharmine functions as a mild serotonin reuptake inhibitor, and one isomer may also have gentle weak reversible MAOI activity (much less potent than that of Harmaline or Harmine), allowing for synergies with other natural phytochemicals that may be deactivated by MAO, including indole derivatives.

In addition, THH has nootropic potential. Studies suggest that the neuroprotective β-carboline harmala alkaloids from the Banisteriopsis caapi vine, including THH, uniquely promote adult neurogenesis. The combination of bioactivities in THH may help support healthy serotonin levels and promote a positive and open mood.
