Antiinflammatory effect of the Indian ayurvedic herbal formulation triphala on adjuvant-induced arthritis in mice

In the present study, attempts have been made to evaluate the antiarthritic effect of the Indian Ayurvedic herbal formulation Triphala on adjuvant-induced arthritis in mice and to compare it with that of the non-steroidal antiinflammatory drug indomethacin. Arthritis was induced by intradermal injection of complete Freund's adjuvant (0.1 mL) into the right hind paw of Swiss albino mice. Triphala (1 g/kg/b.wt) and indomethacin (3 mg/kg/b.wt) were administered orally for 8 days (from day 11 to 18) after adjuvant injection. The levels of lysosomal enzymes, tissue marker enzymes, glycoproteins and paw thickness were increased in adjuvant-induced arthritic animals. The body weight was found to be reduced when compared with the control animals. These physical and biochemical changes observed in arthritic animals were altered significantly to near normal conditions after oral administration of Triphala (I g/kg/b.wt). The results obtained clearly indicate the fact that the Indian Ayurvedic herbal formulation Triphala has promising antiinflammatory activity. Copyright (C) 2007 John Wiley & Sons, Ltd.
