Description
A pale yellow, nondrying oil expressed from the fresh livers of cod fish (Gadus morhua). Cod liver oil primarily contains unsaturated fatty acids (palmitoleic [20%], oleic and linoleic [29% combined]) with smaller amounts of saturated fatty acids (myristic [7.3%], palmitic [8.4%], and stearic [0.6]) and some cholesterol. It is a dietary source of vitamins A and D and was used medicinally in the 18th and 19th centuries for the treatment of rickets. Cod liver oil is a primary agent in the tanning of chamois leather. It is also mixed with zinc oxide and sold in commercial protective creams (Desitin, etc.)
