Wound healing activity of Allium cepa L. bulbs in a second-degree burn wound model in Holtzman rats
Background: The bulb of Allium cepa Linnaeus (onion) is used in traditional medicine as an antidiabetic, antioxidant, antihypertensive, anti-inflammatory, and antihyperlipidemic, among others.

| Sumario: | Background: The bulb of Allium cepa Linnaeus (onion) is used in traditional medicine as an antidiabetic, antioxidant, antihypertensive, anti-inflammatory, and antihyperlipidemic, among others. The lack of information or little knowledge about the effects of Allium cepa L. on skin lesions, specifically burn wounds, arouses interest in studying its effects on these skin disorders. Objective: This study assessed the wound healing activity of Allium cepa L. on second-degree burns induced in Holtzman rats. Method: Thirty-two albino rats were randomly distributed into four groups of 8 rats each, including the Healthy group, the Control group, the Experimental group (Allium cepa L.), and the Standard group (1% silver sulfadiazine). Burn wounds were induced, and topical treatments were performed daily for 21 days. The reduction of the burned body area (mm2) was determined during the experimental time. Albino rats were sacrificed with an excess of surgical anesthesia to obtain tissue samples for histopathological analysis. Results: Standard and experimental groups significantly reduced burned body area (p<0.01) compared to the control group. Histopathological studies showed hyperemic chorion in the Control group, fibroblasts, and collagen in the Standard group, and dermis composed of a reticular stratum of fibroblasts, collagen, and few blood vessels in the Experimental group. Conclusion: Allium cepa L. revealed wound-healing activity on burns induced in Holtzman rats and reduced the damage produced by burns.
