Carlsbad Sprudel Salt was a salt used for medicinal purposes, both as bath salts and taken internally. The salt baths at Carlsbad likely date back to the 12th century.
The mineral springs, to which Carlsbad owes its fame, rise from beneath a very hard kind of rock, known as Sprudelschale or Sprudeldecke, beneath which it is believed that there exists a large common reservoir of the hot mineral water, known as the Sprudelkessel. Several artificial apertures in the rock have been made for the escape of the steam of this subterranean cauldron, which, owing to the incrustations deposited by the water, require to be cleared at regular intervals. Altogether there are seventeen warm springs, with a temperature varying from 164° F. to 107.7° F., and two cold ones. The oldest, best known, and at the same time the most copious spring is the Sprudel, a hot geyser with a temperature of 164° F., which gushes up in jets of ft. thick to a height of about 32 ft., and delivers about 405 gallons of water per minute. Other springs are the Miihlbrunnen, with a temperature of 121° F., which is after the Sprudel the most used spring; the Neubrunnen (138° F.); the Kaiser-Karl-Quelle (112° F.); the Theresienbrunnen (134° F.), &c. The warm springs belong to the class of alkaline-saline waters and have all the same chemical composition, varying only in their degree of temperature. The chemical composition of the Sprudel, taken to a thousand parts of water, is: 2.405 sulphate of soda,. 298 bicarbonate of soda,. 042 chloride of soda, o186 sulphate of potash, o. 166 bicarbonate of magnesia, 0.012 bicarbonate of lithium, and o966 carbonic acid gas. They contain also traces of arsenic, antimony, selenium, rubidium, tin and organic substances. The water is colourless and odourless, with a slightly acidulated and salt taste, and has a specific gravity of Io053 at 64.4° F. The waters are used both for drinking and bathing, and are very beneficent in cases of liver affections, biliary and renal calculi, diabetes, gout, rheumatism, and uric acid troubles. They are very powerful in their effect and must not be used except under medical direction, and during the cure, a carefully-regulated diet must be observed, coupled with a moderate amount of exercise in the open air.
