BACKGROUND: An incision wound is a wound caused by a sharp object. One of the plants that can be used as a traditional medicine for an incision wound is salaon leaves. The prepared form chosen is the gel because it is easy to use and its distribution is faster on the skin. AIM: The aim of the study was to explore whether salaon leaf extract gel meets the quality evaluation requirements and to know the effectiveness of ethanol extract gel of salaon (Parsonsia alboflavescens [Dennst] Mabb.) leaves to cure a scar on male rats. METHODS: Experimental method with salaon leaves as sample. Simplicia of salaon leaves extracted by maceration method, and then arenga gum gel-based formulation, afterward evaluation, and testing of its effectiveness on the healing of incision wound of male rats. Normal data were analyzed by the One Way Analysis of variance (ANOVA) and Post Hoc Tuckey Method. Kruskal-Wallis test used for abnormal data. RESULTS: The whole formula shows homogenous results, normal pH, stability, dissemination and good viscosity, less irritating, and with good adhesion. The results of a statistical analysis of the wound on the 8th day with ANOVA test indicate a significant difference between the five groups p = 0.000 (p < 0.05) and Post-Hoc Tukey Honest Significant Difference test results obtained a concentration of 5% not significantly different from the positive control Placenta extract gel. The optimum dose that can heal incision wound in male rats is 5%. CONCLUSION: The whole formulation qualifies for the quality of the gel formulation. Ethanol extract gel of salaon leaves can heal wound on male rats and the optimal dose is 5%.
