The Healing Effect of N-Hexan- Dichloromethane Extract Root Onosma Bulbotrichum in Second Degree Burns

Background: Wound healing is the process of repair following an injury to the skin and other soft tissues. In this study, the effect of n-hexane d-chloromethane extract (1: 1) of root Onosma bulbotrichum DC on the second degree burn in rabbit model was investigated. Methods: Thirty-six adult rabbits of both sexes were randomly divided into six groups, control (without treatment), negative control (treatment with cold cream), positive control (treatment with silver sulfadiazine), and treatment groups with 5%, 1% and 2% O. bulbotrichum cream and assessed histologically.Results: The best result was shown in 5% O. bulbotrichum group similar to silver sulfadiazine group. The maximum amount of collagen and the tensile strength of tissue were observed in 5% O.bulbotrichum and silver sulfadiazine groups. Histopathological examination showed that burn healing in treatment group with 5% O. bulbotrichum was faster than other groups.Conclusion: The 5% O. bulbotrichum cream was shown to have healing, and anti-inflammatory effects when used in treatment of second degree burns.
