Fabaceae - syn. Rhynchosia phaseoloides (Sw.) DC.; Dolicholus phaseoloides (Sw.) Kuntze; Dolichos pyramidalis Lam.;
pega palo, virility vine, crabseye, Krebsaugenbohne

Woody climber, native to Central and South America, up to 5m long; seeds bright red and black, similar to crab eyes.

„Pega palo is a plant that has received recent and widespread publicity as an alleged aphrodisiac and androgenic agent. One literature report claims clinical efficacy for these effects; however, other investigators could not confirm these activities in laboratory animals. In the present investigation, using a variety of biological test procedures, neither androgenic activity nor an aphrodisiac effect could be demonstrated in laboratory animals.“

„By means of feeding trials with guineapigs, goats and cows, Rhynchosia phaseoloides DC. (Leguminosae), Hamelia patens Jacq., and Pali-courea nicotianaefolia Cham. et Schltd. (Rub-iaceae), all hitherto reputed to be toxic, have been proved to be harmless. In the case of the first-named plant, confusion possibly exists between the seeds and those of Abrus precatorius L., which are very similar in appearance, but extremely poisonous.“ [Contributions to the study of the poisonous plants of Brazil. de Moraes Mello, E.
