Calcium Bromide owes its chief activity to the bromine elements. The Precipitated Carbonate, like the other official carbonate, Prepared Chalk, was formerly of considerable repute in the treatment of infantile diarrheas, but is now used chiefly in dentifrices. Calcium Chloride is too harsh for internal use, even if any known indication existed. The Glycerophosphate and Hypophosphite are practically inert, and should be discarded. The Lactate is the preferable salt, if a definite indication for lime arises. The Sulphide is a crude cosmetic preparation. Chlorinated Lime is a popular and moderately efficient deodorant disinfectant. The Oxide, in the form of liquor cal-cis, is frequently recommended as an antacid to be added to cow's milk in infant feeding, though cow's milk normally has more lime than human milk, in which case probably sodium bicarbonate would be a preferable antacid.
