[Analgesic activity of the aqueous extract from Ximenia Americana].

Pharmacological studies were conducted with the aqueous extract of the bark of the stem of Ximenia americana Linne (Olacaceae) on experimental animals, evaluating the analgesic activities. In the analgesic test, the aqueous extract elicited an inhibitory intensity on the acetic acid-induced writhing response and on the late phase of the formalin test, but possessed only a weak effect on the tail-flick response and on the early phase of the formalin test.
