[Tri-Iodides, according to the laboratory report, depends for its iodin action on potassium iodid.] “... we have an assimilable form of vegetable hydriodates. “The hydriodates of these valuable vegetable alkaloids afford the specific alterative action of iodine without such disagreeable results as the iodism produced by the ordinary iodides.” [“The hydriodates” is an obsolete term formerly applied to iodids of vegetable alkaloids. Iodids of vegetable alkaloids, if present at all in Tri-Iodides, are present in negligible amounts.] “Containing Iodine in an available form, it is obvious that the formula must be beneficial in the majority of syphilitic skin lesions.” The falsity of the first two of these claims and the mischievousness of the last are self-evident. It would be possible, but is unnecessary, to produce an almost unlimited amount of evidence to show the transparent character of the deception by which this preparation is exploited. The referee feels that the nostrum will have been sufficiently characterized when he has mentioned further that the name “Henry’s Tri-Iodides” is blown in the glass of the bottle, that the label contains the recommendation “For Gout, Rheumatism and other Diathetic Diseases,” and that the circular accompanying the bottle recommends the use not only of Tri-Iodides, but also of Three Chlorides, Maizo-Lithium, Campho-Phenique and Satyria in the treatment of many diseases. Three Chlorides (Henry) Three Chlorides (Henry) is advertised as: “An oxygen-carrying ferruginous preparation, suitable for prolonged treatment of children, adults and the aged. Indicated in anemia and convalescence from acute diseases and surgical operations.” The following report on the composition of Three Chlorides is submitted by the Association’s Chemical Laboratory: LABORATORY REPORT It is claimed that each fluidram of Henry’s Three Chlorides contains: “Mercuric Bichlorid 1-72 Gr. “Arsenic Chloride 1-40 Gr. “Proto-Chloride Iron 2-25 Gr. “ ... in a cordial of Calisaya Alkaloids.”
