The aim of this work was to evaluate the acute toxicity of the aqueous extract of Erythrina velutina leaves, which is frequently used in folk medicine as a tranquilizer. The experimental design followed the Guide for Preclinical Toxicity Studies of Herbal Medicines from the Agência Nacional de Vigilância Sanitária (Anvisa, 2004). Adult Wistar rats were treated per os with the limit dose of 5g/kg of the extract and then observed for 14 consecutive days. No animals died and no signs of toxicity were detected either during the behavioral observations or at the autopsies, what indicates a reasonable lack of toxicity for the extract.
