A solution in alcohol, 1 to 99, makes the 2x dilution; subsequent dilutions are made with alcohol.
Bowels.-This is, on account of its easy solubility, a highly corrosive and irritating salt of mercury. It is particularly destructive to mucous membranes, but its influence extends to the serous membranes. It is, therefore, pre-eminently a medicine for dysentery and peritonitis. The dysentery is accompanied by burning in the rectum and anus during stool (canth), by excoriation of the anus and surrounding parts and by very distressing tenesmus. The stools are scanty, frequent and nothing but mucus and blood, or are dark green, blackish and offensive. It is valuable in colitis of the transverse and descending colon and for localized peritonitis, such as may occur with appendicitis or inflammation of the tubes and ovaries.
Urinary.-Mercurius corrosivus has a more irritating effect on the kidneys than metallic mercury, and so is more suitable than the latter for nephritis; urination is frequent, and the urine is scanty, albuminous and bloody, and contains epithelial cells from the uriniferous tubules.
There are burning pains and great tenesmus of the bladder.
All inflammatory affections requiring mercurius corrosivus have a phagedaenic character, and it is therefore to be chosen when ulcers and inflammations are of this kind.
