Catuaba

Also known as Trichilia catigua / Erythroxylum vaccinifolium
CEVIDENCE

Brazil's oldest tonic. Still waiting on its trial.

The honest take
Catuaba is in the same position as muira puama: a real traditional medicine with a real history and an almost empty clinical file. The most useful thing we can tell you is the identity problem — 'catuaba' names at least two unrelated plants with different chemistry, and most labels, including the ones in this category generally, do not specify. We carry it as one of thirteen botanicals in PRIME's blend on the strength of tradition. Treat any confident claim about it as unearned.
What it is
Bark of a Brazilian tree, the country's best-known traditional tonic. Confusingly, at least two unrelated species are sold under the name.
How it works
Animal work points at dopamine and serotonin signalling, which would be a plausible route for mood and interest if it held up in people. It has not been tested in people enough to say. The alkaloids present differ between the species sold under the name, which makes generalisation worse rather than better.
What it does
Traditionally used to support libido, mood and energy. In a blend it is a traditional botanical, nothing more.
Who it's for
Anyone buying the blend as a whole. Not a reason on its own.
How to use it
Daily inside PRIME's blend, with food.
What to expect
No established timeline or effect. Judge the formula, not this line of it.
The research
Grade C. Preclinical work suggests monoamine activity; controlled human trials are absent. The botanical-identity issue — Trichilia catigua versus Erythroxylum vaccinifolium — is a genuine complication in the literature and the trade.

Read the labelNot an erection product and not a treatment for sexual dysfunction. Two different plants are sold as catuaba — check the botanical name if it matters to you.

Evidence grades describe how well an ingredient is studied — A well-supported, C emerging — not a promise of results. Educational, not medical advice. Doses are typical ranges; follow the label on the product.
