The introduction of zinc oxid, aromatic and antiseptic oils and animal fat was a new feature. Somewhat later, and particularly since the passage of the national Food and Drugs Act, no formula or other statement regarding the composition seems to have appeared in the advertisements in the medical press. In the 1906 price-list (p. 170) the following formula appears: “Unguentine represents: “Alum (non-irritating) 15 per cent. “Phenol 2 per cent. “Ichthyol 5 per cent. “Zinc oxid 5 per cent. “Aromatic and antiseptic oils, with especially prepared petrolatum and purified animal fat.” In the price-list issued for 1908--after the Food and Drugs Act went into effect--the following appears: “Unguentine represents: “Alum compound (non-irritating) “Phenol, “Ichthyol, “Zinc oxid, “Aromatic and antiseptic oils, with especially prepared petrolatum and purified animal fat.” Thus the proportions are omitted, and alum becomes “alum compound,” whatever that may mean. In view of the conflicting statements made by the Norwich Pharmacal Company, in regard to their leading specialty, Unguentine, and especially because much stress was laid on the filing of their “guarantee” under the Food and Drugs Act, it was decided to ascertain of what Unguentine really consists. From our analysis we conclude that Unguentine contains not alum but aluminum acetate (small amounts of alum may be present as impurities in the aluminum acetate), zinc oxid, or more probably impure zinc carbonate, and that the entire quantity of both does not exceed 5 per cent. It contains no ichthyol, or if any but the merest traces, and less than 1 per cent. of phenol. The aromatic oils amount to not more than approximately 1 per cent. in all. The ointment-base is, in the main, petrolatum. In Unguentine we have, therefore, another proprietary “specialty,” regarding the composition of which indefinite, false or misleading statements have been made--this irrespective of protestation of honesty by the firm.--(_From The Journal A. M. A., March 27, 1909._) URICEDIN W. A. Puckner and A. H. Clark In view of the results of investigations by Zernik of Uricedin as sold in Germany, and because it is being advertised to physicians in this country, an examination of this product was made in the laboratory of the American Medical Association. Zernik’s report shows how this remedy has varied in its composition as put on the market in Germany. From their analysis the authors find that Uricedin is not a definite chemical compound as is claimed, but is a simple mixture whose composition is approximately:
