In Dyspepsia, when the mucous follicles are supposed to be implicated, much benefit will be derived from the exhibition of this salt, in doses of gr. x., either alone or combined with some aromatic. Dr. Todd * considers that it possesses a specific action upon the mucous follicles.
For this purpose, Dr. Osborne advises the following formula; - T. Guaiaci Am. f3ss., Potass. Sulphuret. gr. v., Liq. Ammon. Acet. fss., M.; to be taken at bed-time, followed by a pint of hot whey. In Chronic Rheumatism, it is occasionally prescribed as a stimulant diaphoretic.
The following mode of application, adopted by Alibert, Dupuytren, &c, has met with great success. In one bottle is placed a solution of the Sulphuret (j. ad Aq. Oij.); in another bottle is placed fij. of dilute Sulphuric Acid. At the time of the application, the patient places a glassful of each in a basin of hot water, and washes the parts affected for half an hour, morning and evening. It has not a very strong odour, and does not stain the linen, - two great advantages. The famous Liniment of Jadelot is composed thus: - ℞ Potas. Sulphuret. ij., Sapon. Alb. lbj., 01. Papav. lbij., Ol. Thymi 3j., M. ft. unguent, bis die applicand. Valentin's Liniment is equally efficacious, and less irritating: - Pot. Sulphuret. 3j., 01. Amygd. j., Camphor j., M. By the use of these a complete cure is effected under fourteen days.
Todd§ advises the local application of a solution (Potas. Sulphuret. 3j., Aq. Oj.) twice a day; or what is more effectual, a sulphuretted bath (iv. ad Aq. Occ). In Ringworm, a lotion, composed of Potas. Sulph. gr. lx. - cxx., Aq. Calcis lbj., has been found very successful. In Sycosis or Men-tagra, Duparc advises that the pustules should be painted, night and morning, with a concentrated solution of the Sulphuret of Potash. It is said to be efficacious. It has also been successfully used as a lotion in Tinea Capitis, Eczema, Lepra, &c.
