Mercurius Sulphuricus.

Hydrargyrum oxydatum sub-sulphuricum. Yellow precipitate. Turpeth mineral. HgSO42HgO. [There is not a little confusion about the identity of this drug in the books. Turpeth is correctly given by Allen as HgSO42HgO. Hering, who proved and introduced it, calls it Turpethum and Turpeth mineral, but gives the formula HgSO4. The Pharmacopaeia of the American Institute of Homoeopathy describes the white sulphate, HgSO4, under the heading Mercurius sulphuricus, but says it is "mentioned in Allen's Encyclopaedia," Vol. vi., p. 325; whereas it is Turpeth, the yellow precipitate, which is there spoken of.] Trituration.

Clinical.-Dropsy. Dysuria. Hydrothorax.

Characteristics.-Lippe is the chief clinical authority for this medicine. He considers it as important as Ars. in dropsies of the chest. The symptoms on which it has been prescribed are clinical, and have been well confirmed. Among them is this: "Pain in right chest extending to scapula; he can scarcely breathe; < 4 to 5 p.m." When Merc. sul. acts well, says Lippe, "it produces a profuse watery diarrhoea with great relief to the patient." It is particularly suited to hydrothorax depending on liver or heart affections. Other confirmed symptoms are: Soreness of tip of tongue. Å’dema of legs. Scanty and scalding urine, but clear. Among the Conditions of Merc. sul. the most peculiar is: < In afternoon; 4-5 p.m. > By profuse diarrhoea (dyspnoea). After diarrhoeic stools there is numbness of legs.
