Eating tends to make people for whom Merc. sulph. is best suited feel irritable. They may be chilly, pale, and anxious.
Key conditions associated with this remedy include digestive complaints and respiratory difficulties. Merc. sulph. is given for breathing that tends to be rapid and short, with burning in the chest, pain in the region of the heart, and weakness that may feel better for sitting up. An irritated stomach, with vomiting, burning in the anus, hot, copious urine, and watery, soft, or violently expelled stools are characteristic of the digestive symptoms treated by Merc. sulph. In some cases, symptoms may be combined: for instance, fluid in the lungs may be accompanied by watery or violent diarrhea and other digestive symptoms.

Merc. sulph. will sometimes help, when you have a case of hydrothorax with quick, short breathing, etc., and burning of the chest.
If you go to an old case of hypostatic congestion, with dropsy, or a case of dyspnoea from hydrothorax, when the Merc. base is present. you will be astonished at the action of this sulphate.

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 Pharmacopæia of the American Institute of Homœopathy describes the white sulphate, HgSO4, under the heading Mercurius sulphuricus, but says it is "mentioned in Allen's Encyclopædia," Vol. vi., p. 325; whereas it is Turpeth, the yellow precipitate, which is there spoken of.] Trituration.
Clinical
Dropsy. Dysuria. Hydrothorax.

Sulphate of Mercury. (HgSO4.)
Hydrothorax, if occurring from heart or liver diseases; dyspnoea, has to sit, cannot lie down. Extremities swollen; stool loose, watery, causing severe burning and soreness; burning in chest. "When it acts well it produces a profuse, watery diarrhoea with great relief to the patient; it is as important as Arsenicum in hydrothorax" - Lippe.
