Therapeutics of Sulphurated Potash, Sulphurated Lime, and Sulphur Iodide

External

An ointment of either will cure scabies and a sulphurated potash ointment (1 in 80) is often used for this purpose in the same way as sulphur ointment. These drugs have been used for many chronic skin diseases; but now they are not often employed. They appear, however, occasionally to do good in cases of acne indurata. Baths containing sulphides in solution are considered by many to be very useful for chronic rheumatic arthritis and rheumatic myalgia. The famous natural sulphide baths are those of Aix-la-Chapelle, Aix-les-Bains, and there are many others, which will be found described in works on general therapeutics; but as in all of them the water is warm, and warm water is beneficial for chronic rheumatism, and the sulphides exist in infinitesimally small quantities, it is very probable that the benefit is due more to the heat of the water than to its constituents. An artificial bath (sulphurated potash, 1; water, 960,) is used for chronic psoriasis.

Internal

Sulphides have been given for chronic rheumatism, various skin diseases, and phthisis; but the evidence of good done is scanty. Sulphurated lime has been given internally in cases of suppuration, for boils, carbuncles, and tuberculous glands in the neck. Halfa grain or a grain .03 to .06 gm. should be given every four hours. It is best made into a pill with acacia, sugar of milk and syrup.
