    Abstract:
    Cordia verbenacea D.C. (Borraginaceae) is a perennial bush plant that grows widely along the southeastern coast of Brazil. Its leaves have been used in folk medicine for their anti-ulcer, anti-inflammatory and cicatrizing activities. We have already described the anti-inflammatory properties of C. verbenacea and its low toxicity in different acute animal models. In the present study, we investigated the anti-inflammatory activity in sub-chronic animal models of a crude leaf lyophilized extract when administered by oral route or topically applied, and concomitantly, its analgesic potency and toxicity to the fetus. Topical administration of the extract inhibited nystatin-induced edema proportionally to the doses used, and this effect at a dose of 4.56 mg/kg body wt. was similar to that observed with 6.0 mg/kg body wt. of naproxen. In miconazole-induced edema, the leaf extract at a dose of 1.24 mg/kg body wt., orally administered, has a very similar effect as compared to nimezulide (2.5 mg/kg body wt.) and dexamethasone (0.2 mg/kg body wt.). At an oral dose of 2.48 mg/kg body wt. the extract showed a very low analgesic effect, and total absence of fetus toxicity at doses of less than 7.44 mg/kg body wt.
