Background & Objective: On the bases of the antiinflammatory, antimicrobial and antioxidant effects of matricaria chamomilla (chamomile) extract. This study was design to determine the effect of topical hydroalcoholic chamomile extract on burn wound healing in albino Rats. Materials & Methods: In this experimental study 30 male albino Rats were randomly divided into 3 equal groups, as sham, control (olive oil) and treatment. Second degree burning was induced in 20% of whole surface area of animal body by diving the back of animal into boiling water for 8 seconds. Animals of control group received no treatment. Animals of olive oil and treatment groups were treated topically by olive oil and hydroalcoholic extract dissolved in olive oil twice a day respectively from the first day of burn induction to complete wound healing. Results: The results showed that there was not significant difference between olive oil and sham groups in all days of experiments. Also there was significant difference in wound healing (p<0.05) between olive oil and treatment groups (62.96±2.70 versus 74.77±2.50) from the day of 20 to the end of experiments. Conclusion: This study showed that the hydroalcoholic chamomile extract has a treatment effect on burn wound healing in animal model.

Background and Objective: Aloe barbadensis Miller plant was used for treatment of wound healing in traditional medicine. However it has different and sometimes contradictory effects. In this study the effect of Aloe barbadensis Miller gel on skin incisional wound healing in Rat was investigated. Materials and Methods: In this experimental study, forty male wistar Rats were randomly divided into 4 experimental groups including: sham operated, control and two treatment groups. Under deep anesthesia, an incision (3cm, full thickness) was made over skin of the back in Rats. The animals of sham group received no treatment. Control group received topical cold cream twice per day (from beginning to end of experiment) and treatment groups' similarliy received topical Aloe barbadensis Miller gel mixed with cold cream (25% and 75%). For computing the percent of wound healing, the area of wound measured at the days 2, 4, 6, 8, 10, 12, 14 and 16 after beginning of experiments. Results: Aloe barbadensis Miller gel at concentration 25% and 75% significantly improved wound healing at 12th day and 8, 10 and 12th days, respectively in comparison with control group. Conclusion: This study indicated that local administration of Aloe barbadensis Miller gel, accelerate the skin incisional wound healing in Rat. This healing is related to the gel concentration.
