Catuaba

What is catuaba?

Catuaba is the name given in Brazil to the bark of several different trees, most often Trichilia catigua and species of Erythroxylum. The bark is traditionally made into teas or tinctures and used as a tonic for fatigue, low mood, poor sleep and low libido. Because “catuaba” can refer to different plants, two products with the same name may not contain the same species.

What the research says

Laboratory and animal studies have explored catuaba extracts for antioxidant, nervous system and blood vessel effects, but human research is very limited. The main human data come from studies of Catuama, a Brazilian product that combines catuaba (Trichilia catigua), guarana, muira puama and ginger. A 28-day safety study of Catuama in healthy volunteers reported no severe adverse reactions and no changes in blood tests (Oliveira et al., 2005). This was a safety evaluation of a combination containing caffeine-rich guarana, so it does not tell us whether catuaba itself has any benefit.

We found no randomized controlled trials of catuaba alone for erectile dysfunction, depression, fatigue, insomnia or prostate health. Statements that catuaba provides “support and protection against ED” are not supported by clinical evidence. Erectile difficulties can be an early sign of heart disease or diabetes, so they deserve a medical evaluation.

How it’s used in supplements

Catuaba bark powder or extract appears in male enhancement and energy blends, typically without standardization. There is no established dose.

Safety information is limited. Avoid catuaba during pregnancy and breastfeeding. People with heart conditions, high blood pressure or mental health conditions, and those taking prescription medicines, should talk with a doctor before using it, since its interactions have not been studied.

The bottom line: catuaba is a traditional tonic with too little human research to know whether it works for anything, and products may not even contain the same plant species. It should not be a reason to buy a men’s or prostate supplement, and it has no demonstrated effect on urinary symptoms or prostate health.

When comparing products, look for the botanical name on the label (for example Trichilia catigua or Erythroxylum catuaba), since the common name alone does not identify the plant. A small, unstandardized amount in a multi-ingredient blend, such as under 100 mg, is very unlikely to have a noticeable effect even if the herb turns out to be active. Persistent low mood, fatigue and insomnia deserve a medical evaluation rather than self-treatment.
