10.22376/ijpbs.2019.10.1.p1-12 Volume 5 Issue 1 2014 (January - March) Anti inflammatory potential of aerial parts of lessThan i greaterThan Phyllanthus longiflorus lessThan /i greaterThan was investigated in the present study using acute and chronic inflammatory models. Carrageenan, dextran and formalin were used as an edematogenic agent to induce hind paw edema in rats and the mean increase in paw volume were measured using plethysmometer. Results showed that methanol extract of lessThan i greaterThan Phyllanthus longiflorus lessThan /i greaterThan at the doses of 100 and 200 mg/kg body weight significantly reduced in hind paw edema induced by Carrageenan, dextran and formalin. Therefore, it is concluded that lessThan i greaterThan Phyllanthus longiflorus lessThan /i greaterThan is useful in the management of inflammatory diseases. M.
