However, there were no in vivo studies which prove its claimed use for wound healing and anti-inflammatory activity. Therefore, the present study aimed at evaluating the in vivo wound healing and anti-inflammatory effects of the leaf gel of the plant in rats.Methods: The leaf gel powder of the Aloe trigonantha was prepared after the gel gets lyophilized. It was evaluated for wound healing activity topically by incorporating it in a simple ointment base at a concentration of 5% (w/w) and 10% (w/w). Excision and incision models were used for wound healing activity in rats. For the excision wound model, wound contraction and period of epithelialization were evaluated, while wound tensile strength was evaluated using an incision wound model. A Xylene-induced ear edema model and cotton pellet-induced granuloma model were used for anti-inflammatory study. The leaf gel powder of Aloe trigonantha was given orally at a dose of 100, 200, and 400 mg/kg in both models of anti-inflammatory studies. An anti-inflammatory effect was measured by reduction of ear edema weight and reduction of wet exudate and dry granuloma weight in both of xylene-induced ear edema and cotton pellet-induced granuloma models, respectively.Results: Treatment of wounds with ointment containing 5% and 10% (w/w) of the gel exhibited a significantly increased wound contraction rate, shorter epithelialization time, and higher skin breaking strength (p< 0.05) compared to controls. Aloe trigonantha leaf gel powder also produced dose-dependent significant reductions (p< 0.05) of inflammation compared to control in both models.Conclusion: Data obtained from this study collectively indicated that Aloe trigonantha is a potential wound-healing and anti-inflammatory agent in rat models of wound and inflammation which provides evidence for the traditional claim.Keywords: Aloe trigonantha, wound healing, anti-inflammatory, granuloma model, ear edema modelTazeze HMequanente SNigussie DLegesse BMakonnen EMengie TDove Medical Pressarticlealoe trigonanthawound healinganti-inflammatorygranuloma modelear edema modelPathologyRB1-214Therapeutics.
