Agnimantha, a classical Ayurvedic drug is one among the dashamoolas, i.e., group of ten plants whose roots form the useful part. It is a main ingredient of many Ayurvedic preparations. Various source plants from the genus Clerodendrum and Premna are used in different regions of the country. In this study, two species of Premna were selected and evaluated for anti-inflammatory activity against carrageenan induced rat hind paw edema. The selected animals were divided into four groups and test drugs were administered orally in the dose of 9ml/kg. Group I received vehicle (distilled water), Group II received leaf decoction of Premna obtusifolia Linn, Group III received leaf decoction of Premna latifolia Roxb and Group IV received indomethacin as standard anti-inflammatory drug. Test drugs and indomethacinwere administered one hour prior to the injection of 0.05 ml of 1% suspension of carrageenan into the sub plantar region of the left hind paw of rats. Study findings indicate that leaves of both the species of Premna have anti-inflammatory potential, P. latifoliabeing superior to P. obtusifolia.
