The oil is extracted from subcutaneous and retroperitoneal fat. The oil is a rich source of fatty acids, oleic acid, linoleic acid and palmitic acid with various antioxidants such as carotenoids and flavonoids. Studies have shown that oil also has anti-inflammatory properties. The leather used to make handbags, shoes, arts and crafts.
