2.7.1. Wound contraction study
All animals were anesthetized with anesthetic ether before wound excision. Wound was created by cutting away 300 mm2 of skin from a predetermined area. Group I was without treatment, Group II was treated with standard neomycin ointment [31], Group III was treated with cinnamon oil alone and Group IV was treated with CMF4 microemulsion. 5 mL of each treatment was applied topically (n = 6) and wound contraction was measured in each 2 days interval, until the wound got completely healed.
