    Skin lesions are a significant problem today. Wound-healing treatments are often scarce and expensive, so this research aims to encourage the development of natural, accessible, and reliable treatments for the population. The objective was to evaluate the wound-healing activity of the ethanolic extract from the leaves of Phoradendron peruvianus (Eichler), 'Tullma,' in Holtzman rats. The study sample was the ethanolic extract from the leaves of Phoradendron peruvianus (Eichler). A total of 48 Holtzman rats were assigned to six work groups. Method: The modified Vaisberg et al. (1989) method for second-intention wounds was adapted and used for this study. Results: According to the diameter of the wound closure on the rats' backs, the group treated with the 5% gel showed a healing activity of 59%. In the histopathological evaluation of the healing tissue, 87.5% of the group treated with the 5% gel showed complete healing, compared to Contractubex, which showed 63%. Conclusion: The extract did show wound-healing activity, both in wound closure and in the histopathological study, with the group treated with the 5% gel showing a higher percentage compared to the positive control.
