Forty male Wistar rats, with average weight of 225 grams, were divided into two experimental groups. A clean wound was induced in the dorsal thoracic region using a 2.0 x 1.5cm metallic mould after ether general anesthesia. In the group An ointment containing cod liver oil, comfrey extract, citrus extract, zinc oxide and carrier were used, and in the group II the wound was only cleaned by the use of isotonic saline. Five animals from each group were submitted to euthanasia at 3,7,14 and 21 postoperative days for histological examination. The group using organic ointment showed superior healing pattern when compared to the group using isotonic saline, represented by collagen fiber formation, vessel ingrowth and total reepithelialization of the epidermis.
