Evaluation of the wound healing activity of an ethanolic extract of Ceylon cinnamon in mice

The present study was conducted to verify the effect of Ceylon cinnamon on experimentally induced excision wounds in rats. Thirty-two rats were divided into four groups of eight rats each. Group A received a placebo containing 1.5% of cinnamon and Group B a placebo containing 3%. Group C, as the control group, didn't receive any treatment and finally Group D received a blank placebo as the reference standard group. Wound healing was monitored on Days 3, 6, 9 and 14 and histological evaluation was carried out on the samples. The results show that cinnamon extract served to accelerate the wound healing process and specifically increased epithelialization in treatment groups compared to the other groups. Thus, this study demonstrates that Ceylon cinnamon may be effective in stimulating the enclosure of wounds.
