Anti-inflammatory, anti-arthritic and analgesic activity of each herbal extract, which is extracted from Bacopa monnieriis, Cassia fistula and Phyllanthus polyphyllus, respectively. The treatment of herbal extract exhibited anti-inflammatory effect as a dose-dependent manner, from 1.25 mg/kg to 12.5 mg/kg, in acute inflammatory models (carrageen and egg-albumin induced rat hind paw edema). It also elicited significant anti-inflammatory activity in chronic inflammatory models (cotton pellet granuloma and Freund's adjuvant induced polyarthritis in rat). In cotton pellet granuloma test, the extract exhibited the inhibitory effect of 23 and 57% at the dose of 6.25 and 12.5 mg/kg, respectively. In Freund's adjuvant induced model, the treatment of the extract of 1.25, 6.25 and 12.5 mg/kg showed the inhibitory effect of 23, 56 and 66% at 8 days, respectively. In the acetic acid-induced model, the extract significantly reduced abdominal writhing in mice when compared to the control group, reducing the mean number of writhing from $41{\pm}2$ in the control group to $17{\pm}3$ and $15{\pm}2$ at the dose of 6.25 and 12.5 mg/kg. From these experiments, the extract, which was extracted from the combination of Bacopa monnieriis, Cassia fistula and Phyllanthus polyphyllus, (w/w/w = 1/2/1) is surprisingly found a significant analgesic and anti-inflammatory activity.
