Reducing the healing time of chronic wounds (HC), with feasible alternatives, accessible and cheap materials, constitutes a strategy to reduce the chronicity of these injuries considered a public health problem. Objective: Determining the healing effect of 2% Potassium Alum on chronic wounds. Methods: Descriptive, prospective, longitudinal, experimental, clinical trial type study was carried out, The population consisted of 48 patients, the entire sample being (occurrence: 100% / confidence: 99%), stratifying into two groups: control (20) with placebo treatment and experimental (28) treated with Potassium Alum. All wounds received bed preparation, with surgical debridement. Results: Systemic factors that affected healing were age ≥ 65 years (77%), hypertension (56.2%), sedentary lifestyle (95.8 %) and local edema (35.4%); and as protective factors, the male gender (72.9%), normal nutritional status (83.3%) and antibiotic and analgesic coverage (100%). Dirty wounds (79.1%), lower limbs (45.8%), necrotizing fasciitis type (41.6%) predominated. The experimental group, depending on the location, experienced a global reduction in healing time (28% granulation and 24% epithelization), with the abdominal region showing the greatest reduction in time (Granulation: 17 days) (Epithelialization: 26 days) depending on the type, an overall reduction in healing time was also observed (27% granulation and 26% epithelialization); Fournier’s gangrene presented a greater decline in time (Granulation: 17.6 days) (Epithelialization: 27.9 days). Conclusion: Lower economic cost, no adverse reactions, and significant healing, were the benefits associated with the use of Potassium Alum.
