USES.--In disorders of the digestive organ administered half hour before meals, to increase the flow of gastric juice, or as an antacid after meals. Young calves when fed on stale skim milk, suffering from dyspepsia, are benefited by one to two drams of bicarbonate of soda, dissolved in each meal of milk. Bicarbonate of soda has become a very popular medicine in the treatment of azoturia in about four ounce doses every four hours. Bicarbonate of soda is used to lessen the irritation of itching skin disorders, as nettle-rash and urticaria, one ounce to a quart of water. Also used as an injection for leucorrhoea. It is an antidote for acid poisoning. DOSES.--Horses, 2 dr. to 4 oz.; cattle, 2 dr. to 2 oz.; sheep and pigs, ¹⁄₂ to 1 dr.; dogs, 10 to 30 gr. SODII CHLORIDUM--SODIUM CHLORIDE--COMMON OR TABLE SALT ORIGIN.--Mined in a native state and obtained by evaporation of brine, spring or sea water. PROPERTIES.--It is officially described as in “colorless, transparent, cubical crystals, or a white, crystalline powder, odorless and heavy, a purely saline taste.” Permanent in dry air. Soluble in two and eight-tenths parts of water at 25° C. (77° F.), and in two and a half parts of boiling water; almost insoluble in alcohol. ACTIONS.--Sodium chloride in small doses is a condiment, restorative, tonic, stomachic, antiferment, alterative, laxative, anthelmintic antiseptic emetic for dogs and used as an injection for pin worms. Animals deprived of salt do not thrive as it is an essential constituent of food necessary to the composition of HCl in the gastric juice, and of blood plasma, from which it is constantly eliminated in the urine. As an emetic for dogs one to four drams of salt, and one dram of powdered mustard dissolved in four ounces of tepid water. Common salt as an eye-wash is a tonic to the eyes; one dram to a pint of water. Feed animals refined salt, as rocksalt contains irritating properties due to its great impurity. A cooling and stimulating lotion for sprains and bruises may be made by dissolving two ounces of common salt, nitrate of potash and chloride of ammonia in a quart of water. Use pure cooking salt in _normal salt solution_, which contains six of one per cent (about fifty grains to a pint), or may be made at once by adding a heaping teaspoonful of pure salt into a quart of sterilized water at a temperature of 100° to 110° F. In cases of azoturia give plenty of salt; it acts as a diuretic, makes the horse thirsty and causes him to drink water freely and flushes the kidneys. DOSE.--Horse, ¹⁄₂ to 1 oz.; cattle, 2 to 3 oz.; sheep, 2 to 4 dr.; pigs, 1 to 2 dr.; dogs, 5 to 20 gr. These doses are stomachic alterative; when used for cattle as a cathartic and vermifuge give 10 to 20 ounces in water, usually combined with magnesium or sodium sulphate.
