Purpose: To evaluate wound healing in diabetic rats by using topic Andiroba oil (Carapa guianensis). Methods: Six male, adult, Wistar rats were distributed into three groups: Sham group (wound treatment with distilled water); Collagenase group (treatment with collagenase ointment); and Andiroba group (wound treatment with Andiroba oil). The wound was evaluated considering the macroscopic and microscopic parameters. Results: The results indicated differences in the healing of incisional wounds between treatments when compared to control group. Accelerated wound healing was observed in the group treated with Andiroba oil and Collagenase in comparison to control group, especially after the 14th day. Morphometric data confirmed the structural findings. Conclusion: There was significant effect in topical application of Andiroba oil on wound healing in rats with induced diabetes.
