Madhu ghrita is a herbal formulation containing honey and ghee (clarified butterfat) as its constituents. The aim of present study is to verify the wound healing and antiinflammatory claims of Madhu ghrita. Incision and excision wound models were used for evaluation of wound healing activity followed by histopathological study in which healing markers like keratinization, epithelization, fibrosis, neovascularisation and collagenation were evaluated in male Wistar rats. The results of Madhu ghrita were compared with the results of untreated control group and results of framycetine sulphate cream, considered as a positive control. The formulation was also tested for antiinflammatory activity, using carrageenan-induced paw oedema in male Wistar rats. The test formulation Madhu ghrita enhanced the tensile strength, which significantly improved over untreated wounds. The tensile strength of untreated control wound was 281±5.82, while with the Madhu ghrita and framycetine sulphate cream 1% w/w, it was 328±8.9 and 398±6.32, respectively. Treatment with Madhu ghrita alone promoted wound contraction and reduced the wound closure time, so increase in tensile strength and wound contraction shows the wound healing potential of Madhu ghrita . Histopathological study shows that proliferation of epithelial tissue promotes angiogenesis, multiplication of fibrous connective tissue due to treatment with Madhu ghrita . The test formulation Madhu ghrita also shows significant antiinflammatory activity when the results are compared with the activity of ibuprofen gel as reference standard. The present study demonstrates the wound healing and antiinflammatory potential of Madhu ghrita .
