“Indicated in Diseases of the Throat and Lungs and of the Digestive Apparatus. Useful in General Debility and Wasting Diseases, Especially when due to Faulty Nutrition. The antiseptic properties of the Emulsion particularly adapt it to the treatment of diseases of septic or bacterial origin.” “Angier’s Petroleum Emulsion is indicated in affections of the throat, lungs and intestinal tract--both subacute and chronic. In diseases of the digestive apparatus due to catarrhal, ulcerative or tuberculous conditions, its peculiar soothing, healing and aseptic properties make its use especially beneficial. Wasting diseases, particularly when due to faulty nutrition, are greatly benefited by its use, one of the most noticeable effects being a prompt and decided increase in weight.” It is, of course, unnecessary to point out that, since petroleum is non-absorbable, Angier’s Emulsion contains no ingredient capable of affecting the respiratory mucous membrane except by local application, for which, indeed, this preparation is evidently not intended. COMPOSITION AND FORMULAS According to a circular which was contained in a trade package recently purchased “Each fluidounce of Angier’s Petroleum Emulsion with hypophosphites contains: 33-1/3 per cent. of our specially purified Petroleum; 9 grains of the combined hypophosphites of lime and soda, chemically pure glycerin and the necessary emulsifying agents.” As regards the nature of the product referred to under the indefinite term “petroleum” the circular states that Angier’s Emulsion is: “... prepared with refined petroleum specially purified for the purpose. By a process peculiarly our own the crude petroleum, obtained from special wells is so purified that all taste and odor and all objectionable and irritating properties are removed, while the full medicinal value of the oil is retained....” The composition assigned to Angier’s Emulsion in an advertising pamphlet “The Petroleum Idea,” issued in 1907 differs in that it is said to contain “specially purified crude petroleum” and that each fluidounce is said to contain 2.84 grains of benzoate of sodium. While these quotations convey the impression that certain medicinal constituents of the “specially purified” product obtained from “special wells” are “retained,” a pamphlet recommending the use of Angier’s Emulsion for the treatment of constipation assures us that it produces the “mechanical effects of the purest petroleum” and that it is “purely mechanical in its action.”[78]
