To analyze curative effect of Folium Eucalypti Robustae decoction in the treatment of residual burn wound and its mechanism.Methods:A total of 74 patients who were admitted to burn department from January 2015 to June 2016 were randomly divided into control group and observation group，with 37 cases in each group.Observation group and control group were respectively treated with Folium Eucalypti Robustae decoction and skin antiseptic，1 time a day.The residual burn wound of two groups were observed，and the clinical effect and bacterium removing were determined.Results:1)The residual burn wound of observation group was significantly better than the control group (P<0.05).2)The healing time of residual burn wound in observation group was (15.7±1.9) days，and was (24.1±2.2) days for control group.Meanwhile the healing rate of residual burn wound in observation group of 7 and 14 days was higher than that of control group.3)There was a remarkable difference (P<0.05) in the effective rate between the observation group (94.59%) and the control group (78.38%).4)The removing rate of staphylococcus aureus，methicillin resistant staphylococcus aureus and pseudomonas aeruginosa of observation group in the 7 and 14 days were all significantly faster than that of control group (P<0.05).Conclusion:Folium Eucalypti Robustae decoction can treat residual burn wound effectively with low price.Consequently，it is worthy of promotion.
