Quantitative estimations[103] indicated the presence of the above-mentioned constituents in approximately the following quantities: [103] Details of this analysis appear in the annual report for 1910 of the Chemical Laboratory of the American Medical Association. Per Cent. Gummy matter having the properties of tragacanth 2.02 Salicylic acid 0.67 Matter having the general properties of wool-fat (lanolin) 0.20 Glycerin 5.50 Volatile matter (water and alcohol) 91.00 Aromatic oils and phenol-like bodies Trace The results of the above analysis, together with advertising matter regarding Zemacol, were submitted to Dr. William Allen Pusey, professor of dermatology and clinical dermatology, College of Physicians and Surgeons, Chicago, and past chairman of the Section on Dermatology of the American Medical Association, with the inquiry whether or not there was any record of investigations regarding the therapeutic value of an extract of the rete mucosum of the sheep and whether in his opinion the claims made for Zematol would be warranted. The following reply was received: “So far as I know, nobody ever thought of or proposed the use of an extract of rete mucosum as a therapeutic agent and if a serious suggestion of that sort had ever been made I believe I would know it. I can conceive of no service which such an extract could render and I think the suggestion of it is a highly fantastic idea. From the analysis which you furnish I should say that the mixture described is substantially the ordinary 2 per cent. solution of tragacanth in glycerin and water with a little antiseptic added to keep it from decomposing. That is a commonly known lotion, modifications of which are used in practically every hospital as a hand lotion, and has no magical virtues whatever. Incidentally, I should think it cost, aside from the labor, about twenty cents a gallon to make it.”--(_From The Journal A. M. A., May 14, 1910._) ZYME-OID W. A. Puckner and W. S. Hilpert Zyme-oid, manufactured by the Oxychlorine Chemical Company of Chicago, is advertised as “a powerful gastro-intestinal antiferment” which will “arrest and prevent bacterial fermentation in any portion of the intestinal tract, whether the media be acid or alkaline.” These extravagant statements, like many others made regarding the properties of zyme-oid, are very similar in character to those made in the circulars accompanying the preparation oxychlorine, manufactured by the same firm and exposed in The Journal, July 6, 1907, page 54.
