Abstract
ALTHOUGH the medicinal value of cod liver oil has been known for 150 years, it is only recently that it has been attributed to the presence of vitamins A and D. It is now known, moreover, that different samples, of oil vary widely in their vitamin potency as well as in their more obvious chemical and physical characteristics. The principles underlying the production of a fine medicinal oil of high activity should be established so that consumers can always be certain of obtaining full benefit from its administration. The recently issued Empire Marketing Board Report by Profs. J. C. Drummond and T. P. Hilditch provides specifications for cod liver oil which are based on the examination of a large number of samples over several years, and makes recommendations for suitable methods of manufacture.
