Physiological Action. Sulphur is a very mild laxative. It is dissolved by alkaline solutions and oils, hence is absorbed from the small intestine, entering the blood, and discoloring silver coins carried by those using it, by forming a sulphide of silver. Sulphurous Acid has great affinity for oxygen, and is a powerful disinfectant and deodorizer, and destructive to all low life. Its gas inhaled is irritant to the glottis, causing inflammation of the passages. The Sulphites and Hyposulphites are partly decomposed by the acid of the stomach, sulphurous acid being given off, and the balance converted into sulphates amid absorbed, undergoing elimination as sulphates by the kidneys. The Sulphides also are partly converted into sulphates. They are irritant to the stomach, etc., extremely nauseous in taste and smell, increase the secretion of the intestinal glands, and are laxative, if administered for some time they impair the blood, and cause emaciation, anaemia, trembling and great debility. Ichthyol, in one case, where a 20 per cent. ointment was applied to an eczema infantile, produced a stupor which continued 12 hours, but from which the child made a complete recovery.
- Therapeutics. Sulphur is used as a laxative when the stools need softening on account of hemorrhoids and fissure, etc. In—
- Chronic Rheumatism and Sciatica,—Sulphur has some repute.
- Scabies,—Sulphur locally as a parasiticide; or a solution of Sodium Sulphite in water, ℨss ad ℥j, as a bath or wash.
- Chronic Bronchitis, with bronchorrhoea,—Sulphurous Acid as spray.
- Acidity, Pyrosis, and Acid Indigestion,—Sulphurous Acid, ♏v, diluted.
- Chilblains,—Sulphurous Acid with Glycerin, is a good application.
- Gangrenous Wounds,—Sulphurous Acid the best antiseptic application.
- Constipation,—the Blue Lick Water, Oj before breakfast; or the Sulphides.
- Lead Poisonings,—Sulphur baths to favor the elimination of the metal.
- Suppuration,—may be prevented or at least limited, by Calx Sulphurata internally, in small doses, gr. 1/5 hourly. For crops of boils, scrofulous sores, glandular enlargements, acne, and suppuration, this remedy proves efficient.
- Skin Diseases,—Sulphur baths are very useful, especially in pityriasis, prurigo, chronic psoriasis and eczema. In the two last-named diseases Unna employs Ichthyol in ointment with excellent results.
