Antiinflammatory activity of the aqueous leaf extract of Byrsocarpus coccineus.

Abstract

The antiinflammatory effect of the aqueous leaf extract of Byrsocarpus coccineus was evaluated using the carrageenan and egg albumin induced rat paw edema, xylene induced mouse ear edema and formaldehyde induced arthritis inflammation tests. The extract administered orally at doses of 50, 100, 200 and 400 mg/kg b.w produced a significant (P<0.05) dose dependent inhibition of edema formation in all four methods used. The results obtained suggest that the aqueous leaf extract of B. coccineus is endowed with effective antiinflammatory activity mediated via either inhibition of phospholipase A(2) (PLA(2)) activity or cyclooxygenase cascade and by blocking the release of vasoactive substances (histamine, serotonin and kinins). These findings seem to justify the use of the plant in traditional African medicine in the treatment of inflammation, including arthritic conditions.
