Effects of Equisetum arvense Ointment on Dermal Wound Healing in Rats 

The aim of this study was to evaluate the effectiveness of Equisetum arvense ointment on dermal wound healing in rats.

The authors studied a total of 56 wounds in four groups of rats. Each wound measured 15 mm x 15 mm. The first group did not receive treatment while the second group was treated with a 1:1 mixture of Vaseline and lanolin ointment. Equisetum arvense ointment doses of 5% and 10% were used in the third and fourth groups. The rats were observed at days 7 and 14 post wounding. The state of the wound healing was evaluated using wound closure ratio and histopathologic studies.

Equisetum arvense 5% and 10% groups and the Vaseline-lanolin group had a statistically significant higher wound closure ratio than the control group (P &0.05). Equisetum arvense ointment groups had a 95.26% and 99.96% wound closure ratio (P & 0.05) and higher dermal and epidermal regeneration, angiogenesis, and granulation tissue thickness after 14 days as compared to the other groups (P & 0.05). P. Equisetum arvense ointment exhibits significant wound healing activity in rats. Further clinical and experimental studies are needed to confirm these results. .
