Catuama is a mixture of Trichilia catigua, Paullinia cupana, Ptychopetalum olacoides, and Zinziber officinalis used in Brazil for sexual enhancement

Catuama is an herbal formula. In Brazil, Catuama containing a mixture of Paullinia cupana (guarana; Sapindaceae), Trichilia catigua (catuaba; Meliaceae), Ptychopetalum olacoides (muirapuama; Olacaceae) and Zingiber officinale (ginger; Zingiberaceae) is used as a body stimulant, energetic, tonic and aphrodisiac.

As of September 2009, we have not seen human research with Catuama herbal sexual formulas.

Catuama and corpus cavernosum effects
The relaxation of isolated rabbit corpus cavernosum by the herbal medicine Catuama and its constituents.
Phytother Res. 2001 August. Antunes E, Gordo WM, de Oliveira JF, Teixeira CE, Hyslop S, De Nucci G. Department of Pharmacology, Faculty of Medical Sciences, UNICAMP, P.O. Box 6111, 13081-970, Campinas (SP), Brazil.
The effects of the Brazilian herbal medicine Catuama and each of its plant constituents (Paullinia cupana, Trichilia catigua, Zingiber officinalis and Ptychopetalum olacoides) were investigated on rabbit corpus cavernosum. Catuama caused short-lived and dose-dependent relaxations. Our results show that of the four extracts assayed, Paulina cupana was the most effective, indicating that it is the main extract responsible for the relaxing effect of Catuama on rabbit cavernosal tissue.

Catuama and heart rhythm
The herbal drug Catuama reverts and prevents ventricular fibrillation in the isolated rabbit heart.
J Electrocardiol. 2007 Nov-Dec. Pontieri V, Neto AS, de França Camargo AF, Koike MK, Velasco IT. Emergency Medicine Research Laboratory, Medical School of University of São Paulo, São Paulo, Brazil.
Catuama was perfused in the isolated perfused rabbit heart. Its effects on intraventricular conduction, heart rate, and monophasic action potential (MAP) duration were evaluated, and sustained VF was induced. The effects on reversion and reinduction of arrhythmia were observed, and new measures were taken in the hearts that reverted. Catuama and Trichilia catigua reverted VF in all hearts, prevented reinduction, and prolonged intraventricular conduction. Catuama prolonged MAP phase 2. On the other hand, P cupana reverted VF in 3 of 5 hearts, but depressed automatism, prolonged MAP phase 3, and did not prevent reinduction. Catuama reverted and prevented VF in this model. Trichilia catigua extract is probably the main agent responsible for the beneficial actions observed.

Safety of Catuama formula
Clinical toxicology study of Catuama, an herbal medicinal extract of Paullinia cupana, Trichilia catigua, Ptychopetalum olacoides and Zingiber officinale in healthy volunteers.
Phytother Res. 2005 January. Oliveira CH, Moraes ME, Moraes MO, Bezerra FA, Abib E, De Nucci G. Miguel Servet Clinical Pharmacology Unit, 415 Jesuíno Marcondes Machado Avenue, Campinas, SP 13092-320, Brazil.
The present study investigated the chronic administration of 25 mL Catuama twice a day during 28 days for any toxic effect on healthy human volunteers of both sexes. No severe adverse reactions or haematological and biochemical changes were reported.

Aphrodisiac herbs available over the counter
These include maca, tongkat ali, butea superba, cnidium monnieris, tribulus terrestris extract, horny goat weed, avena sativa, LJ100, muira puama, catuaba, ginger, cistanches, and yohimbe bark extract.

Antinociceptive Activity of Trichilia catigua Hydroalcoholic Extract: New Evidence on its Dopaminergic Effects.
Evid Based Complement Alternat Med. 2009 Oct 8. Viana AF, Maciel IS, Motta EM, Leal PC, Pianowski L, Campos MM, Calixto JB. Department of Pharmacology, Center of Biological Sciences, Universidade Federal de Santa Catarina (UFSC), Campus Universitário, Trindade, 88049-900, Florianópolis, SC, Brazil.
Trichilia catigua is a native plant of Brazil; its barks are used by some local pharmaceutical companies to prepare tonic drinks, such as Catuama. The present study was addressed to evaluate the effects of T. catigua hydroalcoholic extract in mouse nociception behavioral models, and to evaluate the possible mechanisms involved in its actions. The antinociceptive effects of T. catigua extract seem to be mainly associated with the activation of dopaminergic system and, to a lesser extent, through interaction with opioid pathway.
