Anti-inflammatory activity of Bacopa monniera in rodents.

The ethanol extract of Bacopa monniera (Scrophulariaceae) exhibited marked anti-inflammatory activity against carrageenan-induced paw edema in mice and rats, an acute inflammatory model. To assess the possible mechanism of anti-inflammatory action against carrageenan, the ethanol extract was treated with chemical mediators (histamine, serotonin, bradykinin, prostaglandin E(2) and arachidonic acid)-induced edema in rats. The extract selectively inhibited prostaglandin E(2)-induced inflammation. Thus, it may be inferred that B. monniera possesses significant anti-inflammatory activity that may well be relevant for its effectiveness in the healing of various inflammatory conditions in traditional medicine.
