Evaluation of wound healing and antiinflammatory activities of new poly-herbal formulations

Abstract

Present investigation evaluated the impact of poly-herbal formulations comprising extracts of Zingiberofficinale, Curcuma longa, Aloe barbadensis, Citrus aurantium, Emblica officinalis and castor oil on wound healing activity using excision wound model and antiinflammatory activity using formalin-induced pawedema method. Ointments containing 2, 4 and 6 % w/w of extracts were made and used in wound healing action and all the formulations significantly (p<0.01) reduced the wound area. Ointment of 6 % w/w has shown better results than 2 and 4 % w/w. These results were compared to that of the standard framycetin. Poly-herbal formulation-1, poly-herbal formulation-2 and poly-herbal formulation-3 were prepared and used at doses of 100, 300 and 500 mg/kg to determine antiinflammatory activity. All poly-herbal formulations significantly (p<0.01) inhibited formalin-induced rat paw edema. Poly-herbal formulation-3 displayed greater inhibition than poly-herbal formulations 1 and 2. These results were comparable to that of the standard diclofenac. Present work and previous studies on poly-herbal formulations corroborates that these are safer and effective in treating inflammation and wounds.
