Abstract

The wound healing effect of Milicia excelsa ointment was evaluated in three groups of rats using the excision wound model. Also the antibacterial effect of M. excelsa extract on Pseudomonas aeruginosa and Staphylococcus aureus was investigated. The result of the study showed that the ointment of M. excelsa significantly enhanced wound contraction and epithelialization. The epithelialization time in the M. excelsa ointment treated group was significantly shorter than time of epithelialization in the base treated group. On day 7, wound sections of rats treated with M. excelsa ointment showed abundant neutrophils, few macrophages and few fibroblasts while in the base treated rats, abundant neutrophils, few macrophages and few fibroblasts were seen. By day 14, wound sections of M. excelsa ointment treated rats showed abundant fibroblasts, mild collagenization, moderate macrophages and vascularization whereas moderate neutrophils, few macrophages and few fibroblasts were seen in the sections of base treated rats. M. excelsa extract at 100, 50, 25 and 12.5 mg/ml inhibited the growth of S. aureus but not P. aeruginosa. In this study, daily application of M. excelsa ointment enhanced wound contraction, epithelialization and fibroplasia. These results provide scientific evidence showing the efficacy of M. excelsa leaves in wound healing.
