Abstract: Shorea robusta Gaertn. f. (Sal) is one of the most important traditional Indian medicinal plants. The resin of the plant has been used in the treatment of inflammation in folklore medicine. In the present study, ethanolic extract (70%) of S. robusta resin (SRE) was investigated for its anti-inflammatory and antipyretic activities. Acute inflammation was produced by carrageenan-induced hind paw edema and sub-acute by cotton pellet-induced granuloma in male Wistar rats. The antipyretic activity of SRE was studied using Brewer’s yeast-induced pyrexia in rats. The rats were divided into five groups with five animals in each group. Group I was treated with vehicle i.e. 1% v/v Tween-80 and served as control. Groups II to IV were treated with three different doses of SRE (30, 100 and 300 mg/kg orally). Group V was treated with standard drug etoricoxib (10 mg/kg orally). The anti-inflammatory activity of SRE was assessed by per cent reduction in edema volume of carrageenan-induced hind paw edema and by per cent decrease in granuloma formation in cotton pellet-induced granuloma test. SRE (100 and 300 mg/kg) produced a significant reduction in edema volume and decrease in granulation tissue formation in rats. Significant reduction in pyrexia was observed at all the dose levels of SRE i.e. 30, 100 and 300 mg/kg. The results of the present study demonstrated anti-inflammatory and antipyretic activities of S. robusta resin and supported its traditional therapeutic use in painful inflammatory conditions and fever.
