“=Something had to be done; and Burnham’s Soluble Iodin is that which has been done=” fulfils, in its blatant assertiveness, all the requirements of nostrum advertising. The results of the analyses are not, therefore, a surprise. Secrecy is just as essential today to the successful exploitation of this class of proprietaries as it was before the demand for formulas became so universal. The requirement of publicity is evaded, therefore, in one of two ways: Either a formula is given which is false, or at least meaningless, or else the claim is made that the method of preparing the product is a unique and remarkable secret that is possessed only by the manufacturers. The Burnham Soluble Iodin Company uses the latter device. Meanwhile, physicians will be perfectly justified in viewing with suspicion all claims based on such conspicuously unscientific premises, more especially so when these claims fail to find substantiation on careful and painstaking analyses. In brief, whenever the physician wishes to administer free iodin, Lugol’s solution (Liquor Iodi Compositus, U. S. P., Physician’s Manual, page 84) is an inexpensive and perfectly available preparation.--(_From the Journal A. M. A., March 28, 1908._) “HYDROCYANATE OF IRON--TILDEN” W. A. Puckner and W. S. Hilpert Among the many inquiries received regarding the composition of secret remedies was one in reference to “Hydrocyanate of Iron” manufactured by the Tilden Company, New Lebanon, N. Y. This preparation is advertised as being “unexcelled as a remedy for epilepsy, hysteria, chorea, neurasthenia, locomotor ataxia, neuralgia, migraine, anemic headaches, and all convulsive or reflex neuroses dependent on impairment of the brain or spinal cord.” It is also said to be “valuable in uterine reflex neuroses due to congestion; in amenorrhea due to anemia and chlorosis and suppressed menstruation.” The term “hydrocyanate of iron” is an unfamiliar one and is not found in any available reference work on chemistry. Thinking that the term might have been loosely applied to ferrocyanid of iron, or Prussian blue (a compound once suggested for epilepsy, but long ago considered useless), the correspondent wrote to the manufacturers asking if such were the case. The Tilden Company answered: “... our preparation Hydrocyanate of Iron is not Prussian blue in any sense of the word. Prussian blue has no curative properties as applied to all forms of epilepsy. Prussian blue is Ferrocyanid of Iron while our preparation is Hydrocyanate of Iron.” The only statements in the Tilden Company’s advertising matter regarding the composition of hydrocyanate of iron are the following: “Hydrocyanate of Iron (Tilden’s) is a correct and scientific combination of well known principles.” “Hydrocyanate of Iron (Tilden’s) combines well known properties of ferruginous salts with the sedative action of Hydrocyanic acid.”
