Abstract:  Several previous studies have demonstrated improved wound healing associated with natural-based formulations. Therefore, the purpose of this study was to assess the efficacy of a topical formulation containing both a Brazilian micronized propolis extract and a Peucedanum ostruthium leaf extract for the treatment of wounds created by surgical punch in rats. The study was conducted for 14 days and animals were treated as follows: gauze group (G), polyethylene glycol base ointment (Control), AlpaWash (an ointment containing a Brazilian micronized propolis extract and Peucedanum ostruthium leaf extract [Treatment]), and polysporin (one of the most commonly used topical antibiotic ointments, based on bacitracin zinc and polymyxin B sulfate [Reference Standard]). In general, the results demonstrated that ointments, due to occlusiveness and the ability to maintain moisture under the damaged area, offered improvements when compared to lesions without any treatment. Additionally, the presence of phenolic and flavonoid compounds, as well as antioxidants and antimicrobials, offered improved stimulation and could accelerate wound healing. The Control, Treatment, and Reference Standard groups were able to close the lesion, as measured by the wound healing rate determination and follow-up photographs. However, AlpaWash and Polysporin presented some additional benefits— anti-inflammatory activity, measured using myeloperoxidase and histological count, as well as fibroplasia and hydroxyproline production, suggesting that skin with a better quality could be formed following these two treatments. Therefore, based on the current concern of antibiotic overuse in wound healing, the emergence of multi-resistant organisms and the decrease in newer antibiotics, AlpaWash is considered a prominent formulation to be employed in wound-healing applications.
