In the present study, Sonerila tennevelliensis whole plant was extracted with ethanol and evaluated for antiinflammatory activity in rats using a carrageenan induced paw edema method. Ethanol extract exhibits potent antiinflammatory activity at 500mg/kg at 3hr administration. The study was compared with standard drug indomethacin (10mg/kg). Observed pharmacological activity in the present study provides scientific validation of ethnomedical uses of this plant in treating acute inflammation.
