                            Abstract
                            Background: Wound healing is the body's natural repair process after injury. Due to its high antioxidant capacity and many effective components, this study aimed to assess the impact of topically applied Heracleum persicum extract on rat full-thickness incisional cutaneous wound healing.
Methods: After induction the wound, sixty male rats were divided into four groups: control, basal cream, H. persicum 5% and 10% and were treated daily with saline, basal cream, H. persicum 5% and H. persicum 10% for 14 days, respectively. The animals were euthanized at 7, 14 and 21 days post-injury, and samples were collected for histopathological and biochemical analysis.
Findings: A prominent decrease in the wound area was observed in the treatment groups, particularly H. persicum 10% compared to the control group. Additionally, treatment with H. persicum decreased the number of lymphocytes and improved the number of fibroblasts at the earlier stages and increased the number of fibrocytes at the later stages of wound healing. Also, re-epithelization, tissue alignment, higher maturity of the collagen fibers and large capillary-sized blood vessels revealed significant changes in the treatment groups, especially H. persicum 10% compared to the control group. H. persicum extracts increased hydroxyproline and glycosaminoglycans contents and elevated total antioxidant capacity, while decreased malondialdehyde compared to the control group.
Conclusion: This study showed that H. persicum promotes wound healing activity. This property can be attributed to its action on blood vessels, modulation of inflammation, its role in initiating more collagen and glycosaminoglycan production and decreasing oxidative stress.
