Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy

What is Catuaba?

Catuaba refers to the bark of several Brazilian trees (often Trichilia catigua or Erythroxylum species) used in traditional South American medicine as an aphrodisiac, stimulant and tonic. It is frequently paired with muira puama in libido and 'male enhancement' formulas.

What Catuaba is commonly used for

In supplements, Catuaba is most often included for men's vitality support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.

How Catuaba works

Catuaba contains alkaloids and other compounds proposed to have mild effects on dopamine signalling, circulation and the nervous system. The mechanisms are not well characterised, and the aphrodisiac claims are largely traditional.

What the evidence says

Here's an honest snapshot of what published research suggests about Catuaba — including where the evidence is limited.

• Animal and laboratory studies suggest possible effects on mood-related neurotransmitters and circulation, but human evidence is essentially absent. (PubMed research)
• There are no good controlled human trials confirming libido or performance benefits. (PubMed research)

Typical dosage used in studies

There is no established effective dose; it is used as bark, extract or in blends. This is research information for context, not a recommendation — confirm what's appropriate for you with a healthcare professional.

Side effects and safety

Considered generally well tolerated traditionally, but human safety data are limited.
