Mercurius Dulcis signs and symptoms of the homeopathy medicine from the Dictionary of Practical Materia Medica by J.H. Clarke. Find out for which conditions and symptoms Mercurius Dulcis is used

      Subchloride of Mercury. Calomel. Mercurous chloride. HgCl. Trituration.


Catarrh. Condylomata. Conjunctivitis. Deafness. Diarrhoea. Eustachian tube, affections of. Gastromalacia. Meningitis. *Peritonitis, *plastic. Prostatitis. Throat, sore.



*Mere. dulc. Is responsible for a large amount of the mercurialization of the past and for some of the present. As a comparatively mild and slow-aching form of mercurial, it has none of the corrosive effects of the per chloride, but it has all the power of the metal in it nevertheless, and it has had its own share of disasters. For constipation and any affection which could be ascribed to the liver, blue pill was at one time about the only recognized remedy. Some homoeopaths have adopted a modification of this by prescribing *Mercurius dulc. ix in two-or three-grain doses as a direct purgative. But as *Mercurius dulc. has caused both constipation and diarrhoea, it is probable that the action is roughly homoeopathic. The Schema is made up for the most part of toxicological and clinical symptoms, though a proving of potencies has been made. It is especially scrofulous children who are liable to remittent bilious attacks who are benefited by *Mercurius dulc. The keynote of *Mercurius dulc. in this as in other complaints is *pallor: “pallid as a corpse,” and with this a “flabby bloatedness” of appearance. Pale, scrofulous children who have swelling of cervical and other glands. Skin flabby and ill nourished. Another leading feature of *Mercurius dulc. is inflammation with plastic exudation. I have seen *Calomel in old-school practice rapidly resolve and cure a violent meningitis, with wild delirium, in a girl of five. In this case there was probably plastic exudation on the membranes. Plastic peritonitis. Gluing up of Eustachian tube with catarrh. Scrofulous inflammation in general and particularly of the eyes. Soreness round anus is a leading indication in many affections when it occurs as a concomitant.


*Antidoted by: Hepar Compare: In stringy stools, Sul-ac. Catarrhal inflammation of middle ear, Kali-m. Eustachian tube closed, deafness of old age, Kali-m.
