A large amount of confusion exists today regarding the actual species of tree that is harvested in Brazilian forests and sold around the world as “catuaba.” Experienced Brazilian harvesters will refer to two species: a “big catuaba” and a “small catuaba.” The confusion thickens when relating these trees to approved botanical species names. “Small catuaba” is Erythroxylum catuaba (A. J. Silva ex. Raym.-Hamet – the name was accepted in 1936), which grows 2-4 m tall and sports yellow-to-orange flowers and, in Brazil, is referred to as catuaba. “Big catuaba,” in the mahogany family, is Trichilia catigua (A. Juss.), which grows 6-10 m tall, has cream-colored flowers and – in Brazil – is referred to as catigu and angelim-rosa.
Moreover, three other (unapproved) botanical names for catuaba are used incorrectly in herbal commerce today: Juniperus brasiliensis (which is thought to refer to “small catuaba”), and Anemopaegma mirandum and Eriotheca candolleana, which are completely different species altogether. Anemopaegma is a huge tree in the Bignonia family, growing to 40 m tall and called catuaba-verdadeira in Brazil. This species of tree is now harvested and exported out of Brazil by inexperienced or unethical harvestors (resulting in the incorporation in herbal products sold in the U.S. today) as just “catuaba.”
The catuaba tree is a small tree with orange and yellow flowers. It produces an oval-shape fruit that is not edible. The catuaba tree belongs to the genus erythroxylum, which contains several species from which cocaine is derived.
Clinical studies on catuaba also have shown results related to its antibacterial and antiviral properties. A 1992 study indicated that an extract of catuaba (Erythoxlyum catuaba) was effective in protecting mice from lethal infections of Escherichia coli and Staphlococcus aureus, in addition to inhibiting HIV significantly.
The study found that the pathway of catuaba’s anti-HIV activity stemmed (at least partially) from the inhibition of HIV absorption into cells, and suggested that catuaba had potential against opportunistic infections in HIV patients. A U.S. patent was granted (in 2002) to a group of Brazilian researchers for a catuaba bark extract (Trichilia catigua).
According to Dr. Meira Penna, catuaba “functions as a stimulant of the nervous system, above all when one deals with functional impotence of the male genital organs . . . it is an innocent aphrodisiac, used without any ill effects at all.” In Brazil it is regarded as an aphrodisiac with “proven efficacy” and, in addition to treating impotence, it is employed for many types of nervous conditions including insomnia, hypochondria, and pain related to the central nervous system (such as sciatica and neuralgia).
For generations, indigenous people have used catuaba bark not only as an aphrodisiac but also for many health benefits. It has been used to lessen pain, improve memory, calm anxiety and alleviate fatigue, among other benefits.
In the last several years, its popularity has grown in the North American herbal market, with various products (especially libido formulas) now available in health food stores. Catuaba is also showing up in other formulas for depression, stress and nervous disorders. (The jury’s still out as to which species is being sold, however!) Interested consumers should seek a reputable manufacturer and product – with a verified plant source and botanical species for the herbal ingredient being sold.
