This study was investigated on anti-inflammatory and analgesic activity on Gu-Mi-Gang-Hwal-Tang which has been used for the treatment of common cold and headache, arthralgia, fever in oriental medicine. The anti-inflammatory activities of Gu-Mi-Gang-Hwal-Tang water extract (GMGHT) on the carrageenin induced edema, acetic acid induced edema, and corton oil induced granuloma pouch in rats were examined. The analgesic effect of the GMGHT was investigated utilizing acetic acid induced writhing syndrome in mice. The antipyretic activity of the GMGHT was also investigated. The oral administration of GMGHT has been shown the anti-inflammatory activities in 1% carrageenin and acetic acid induced edema in rats. The GMGHT has been shown significant inhibitory effects on glanuloma and exudate formation in rats, especially the GMGHT (450 mg/kg) has the efficacy more than the GMGHT (150 mg/kg). The writhing syndromes induced by acetic acid in mice were inhibited, especially analgesic activity of the GMGHT (450 mg/kg) is similar to that of piroxicam and antipyretic activities were recognized in rats. In the present study, the GMGHT is indicated to have the anti-inflammatory, analgesic and antipyretic activities.
