Comment:--While the name gives the impression that ozone or some similar substance is an essential constituent of Glycozone, or else that the preparation is a compound or derivative of ozone, and while the earlier advertisements stated that Glycozone was “glycerine combined with ozone,” the examination made by the Council shows that there is no basis of fact for such inferences. In the advertisements the “chemical formula” C_{3}H_{6}O_{4} + C_{3}H_{8}O_{3} appears under the word Glycozone. From the Council’s report it is apparent that C_{3}H_{6}O_{4} stands for glyceric acid and the C_{3}H_{8}O_{3} for glycerin, and that these, therefore, indicate the chief constituents of Glycozone. Few, doubtless, would recognize the first formula as being that of a glyceric acid, a product practically unknown in medicine, nor would many associate glycerin with the second. The evident intent is that physicians should accept the formula as a badge of respectability. According to the label on a trade package, Glycozone is “prepared only by Charles Marchand, chemist,” and is {“}an absolute cure for dyspepsia, catarrh of the stomach, ulcer of the stomach, heart-burn,” etc. The label further reads: “This remedy is positively harmless. By destroying the microbian element in the stomach it prevents the fermentation of food and stimulates digestion.” An examination of medical literature fails to reveal any basis for these claims. While glycerin possesses some antiseptic properties, it is evident that the glycerin which constitutes 90 per cent. of this remedy is not the agent that gives the glycozone such phenomenal virtues. General literature contains nothing that would indicate that glyceric acid in any quantity, with or without glycerin, possesses these miraculous properties. If by “microbian element” is meant microbic organisms, the statement is without foundation. There is nothing in this product which possesses these bactericidal powers. The circular which accompanied a trade package envelops the preparation in an air of mystery. Derivation from, or close relation to, ozone and hydrogen peroxid is vaguely hinted at, without definite assertion. Thus, the chief therapeutic properties of glycozone and hydrozone are compared as follows: “Hydrozone instantly destroys the microbian element, leaving the tissues beneath in a healthy condition.” “Glycozone acts more slowly, but not less certain as a stimulant to healthy granulations.” [Illustration: Much-reduced photographic reproduction of one of the older Glycozone advertisements. Attention is directed to the false claim that this nostrum is “glycerin combined with ozone.”] There is no similarity between the action of hydrozone, which is a hydrogen peroxid preparation, and glycozone, which consists of a mixture of glycerin and glyceric acid. The representation is false and misleading. The following statement, also, is an unwarranted exaggeration of the facts:
