Cod-liver oil is obtained from the liver of the cod, Gadus morrbuae, and is in the form of a fixed oil, containing biliary principle, traces of iodine, bromine, phosphorus, lime, magnesia, iron, soda and sulphuric and phosphoric acids; also a principle known as gaduin. By distillation with ammonia, it yields propylamin. The pale oil is considered to be the best for internal use, and is the officinal preparation. Iodine, phosphorus, bromine and iron are often combined with cod-liver oil, but are considered to add nothing to its therapeutical powers. The special medicinal value of this oil depends upon the gaduin and propylamin, which are constituents of bile, iodine, phosphorus, bromine, etc., as well as upon the common ingredients of animal fat. The phosphates, hypo-phosphites, or the lacto-phosphate of lime are often combined with cod-liver oil, with excellent effects.
