Improvements in and relating to the Preparation of Natural Mineral Salts for Medicinal purposes. I, Eiiicii Langhelx), of Lindeiistrassej 05, Waxidsbeck, near Hamburg, iu tbe Empire of Germany, Doctor of Medicine, do hereby declare tlie nature of this invention to be as follows; — Mineral waters such as the waters of AViesbaden, Ems, Carlsbad, Yichv and the like, are rrrostly taken in the liquid state by patients. The natural salts have however been separated from, these waters and lozenges have been made from them. These lozenges are however very disagreeable to many patients so that for this reason they Iwve often to be dissolved in liquids. Although the •ozenges atford a convenient way of taking the mineral salts their production 10 in this form has great inconveniences. Furthermore, as a rule the mineral .salts are decomposed in the atmosphere especially in the tropics and are spoiled in consequence of their hygroscopic nature. Again ph3^sicians agree that the most complete and expeditious assimulation of medicines is effected where the medicine is finely distributed and offers the greatest possible surface in passing lo ihrough the digestive canal for the salts to be abstracted. The waters cannot be exported to the tropics inasmuch as when the waters * ^ are kept in bottles or jars a chemical decomposition takes place, and especially in hot zones, and thus the waters are spoiled. This inconvenience is avoided br^ the present invention in which the stabilit}^ 2:) of the mineral salts is guaranteed in such manner that the mixing and drying is effected within a vacuum at such temperatures as sliall not cause chemical deconrposition or chemical change of some of the salts, such for example as the reduction of sodium bicarbonate into sodium carbonate. Accordiirg to the invention, it is iirtended to employ the mineral salts obtaiired 2,5 rn this wa}^ so that the}- shall not deteriorate under the infiuejice of dampnesa and in such manner that their administration is facilitated. According to the invention, the mineral salts are worked into cakes, biscuits or pastry or the like so that thus the niineral salts to a great extent lose their disagreeable taste, and ilia}- easilv be taken in this form at any time of day. OQ TT'.e working of the salts into cakes has moreoYer the great advantage that the patient may constantly carr^^ with him nourishment which is necessary to his malady. The cakes inay also be employed for food sucli as eggs and flour, and as such Avould contain inineral salts the remedy may be taken in various ^ V > X XU ii3 • ^ . . or In the case of sensitive or unstable salts which would be decomposed at the kio'h temperature necessary for baking, the salts ma^^ be added in a concentrated sofution to the complete biscuit or cake which may be then dried at a low ^^^The content of the salts in the biscuits or cakes ma^’ be determined according 40 in requirements, and a special mark may be made on the biscuit or cake as ibe content.
