Catuaba is a natural remedy derived from the bark of trees found in the Brazilian rainforest. Formulations vary depending on the type of tree selected; Erythroxylum caatingae, Trichilia catigua, Anemopaegma arvense, and Micropholis caudata are some possibilities. But all of them are said to stimulate the nervous system and offer aphrodisiac properties.
Catuaba is an herb. People use the bark to make medicine.
People use catuaba for sexual arousal and performance, agitation, poor memory, and many other conditions, but there is no good scientific evidence to support these uses.
The active ingredient in catuaba is believed to be alkaloids dubbed catuabines. Alkaloids are organic compounds from plants, some of which have psychoactive effects. Examples include caffeine, morphine, strychnine, and nicotine.
In the United States, catuaba is mainly sold as a dietary supplement in capsule, extract, and powder forms.
