چکیده

This study was to evaluate anti-inflammatory and analgesic effects of the aqueous extract of leaves of Chromolaena odorata (Asteraceae) collected in Brazzaville-Congo. Acute inflammation was induced by using the carrageenan and formaldehyde models, and chronic inflammation by the cotton pellet induced granuloma model. Analgesic effect was evaluated by using the acetic acid-induced writhing, the pressure induced by the analgesymeter as well as the pain induced by formaldehyde. The results obtained show that aqueous extract (400 and 800 mg/kg) inhibits the edema induced by the carrageenan and formaldehyde. Moreover, this extract at the doses used (400 and 800 mg/kg) significantly inhibits granuloma fabric induced by cotton pellet. In addition, aqueous extract (400 and 800 mg/kg) inhibits significantly the pain induced by the three methods used. In conclusion, aqueous extract of C. odorata has anti-inflammatory and analgesic effects. These observations justify the traditional use of this plant in the treatment of inflammatory pathologies and the pain.
