This study describes an eighteen-year-old filly after an injury in the region of the dorsal left metatarsus, admitted to veterinary assistance. In addition to the normal treatment, which was characterized by cleaning and topical application of povidone-iodine, sunflower-seed oil was applied locally in order to improve and fasten wound healing. Macroscopic and clinical improvements of the wound healing were observed. The preliminary chemical and physical analyses have shown the stearic acid as the main component. The results suggest that the sunflower-seed oil enable a faster wound healing in horses.
