The acute toxicity (LD50) and the anti-inflammatory effect of the crude freeze-dried aqueous extract of the leaves of Bryophillumcalycinum Salisb. (EBALBc) was evaluated, on the rat paw edema induced by carrageenin and dextran. The dose of 500 mg/kg (p.o) inhibited the paw edema induced by dextran in a significative manner (p < 0.05, ANOVA, Student Newman-Keuls test) 60 and 90 minutes, after stimulus while only the oral dose of 1 g/kg of EBALBc inhibited the paw edema induced by carrageenin. The results indicated an anti-edematogenic effect of the extract when tested on the paw edema induced by dextran and carrageenin, suggesting larger specificity of action on the edema induced by dextran. The EBALBc administered orally, in the doses of the 0.1 to 8 g/kg, it did not cause death, making impossible to determine the LD50. |
