The use of medicinal plants as an alternative to treat ailments and/or diseases is gaining great importance for the creation and research of new formulations. Objective: To determine the wound-healing activity and dermal toxicity of the ethanolic extract from the tubers of Ullucus tuberosus Caldas, 'olluco,' in experimental animals. Methods: The plant species was collected in the Panao community, Huánuco department, Peru. An ethanolic extraction of the Ullucus tuberosus Caldas 'olluco' tuber was performed for phytochemical analysis. The wound-healing activity was assessed using the Vaisberg et al. technique, for which three creams based on the plant species were prepared at concentrations of 0.5,5, and 10%. These were compared with two standard groups: a 1% Croton Lechleri 'Sangre de Drago' cream prepared naturally, and onion plant stem cells (Emolan®), and a control group ('Vaseline'). Dermal toxicity was determined using the Contero technique, where a single oral and dermal dose of 5000 mg/kg of the extract was administered to rats. Results: Phytochemical analysis determined that the extract is soluble in distilled water and contains primary and secondary metabolites. The 10% concentration cream obtained 86% healing efficacy compared to the intact skin sample. In the toxicological evaluation, no Holtzman strain rat showed dermal toxicity. Conclusion: It was determined that the ethanolic extract from the tubers of Ullucus tuberosus Caldas, 'olluco,' does present wound-healing activity and does not possess dermal toxicity.
