The antipyretic effect of the hexane, chloroform, ethyl acetate and methanol extracts obtained from Rumex nepalensis (Polygonaceae) roots was investigated in rats at 500 mg/kg by oral route. The investigation results showed that hexane and methanol extracts have significant antipyretic activity. The results provide a scientific rationale for the folklore claim as an antipyretic agent.
