Reason for use

The history of this remedy is a romantic one. When Dr. Alexander Villers was an infant he had diphtheria. Known remedies had failed to arrest the disease, and his father, Dr. Dominic von Villers, was in despair. Taking counsel with his friend, Dr. Beck (of Monthey in Switzerland), the latter was struck with the likeness of the case to the effects of Merc. cy. in some poisoning cases, reports of which he had just been reading. He suggested the remedy A small quantity of the salt was procured and an attenuation rapidly made and administered. Improvement soon set in, and recovery happily followed. The patient, saved by Merc. cy., lived to do most brilliant work with the same remedy when practising in St. Petersburg, and Merc. cy. has taken a sure place at the head of remedies for this affection. The local symptoms are very clearly defined, and among the general symptoms profound prostration, coldness, and cyanosis are leading indications. Villers had better results with the 30th than with any lower attenuation. Merc. cy. is also a very efficient prophylactic in diphtheria. In the sensational New York poisoning case of February, 1899, Mr. Henry C. Barnett, the victim, was treated for diphtheria by his doctors before the cause of the illness was discovered. Beck (Rev. Hom. Fran., xii. 153) mentions among the leading symptoms: extreme feebleness, trembling, syncope. Icy coldness; general coldness with nausea. Diphtheritic membrane in throat, mouth, and at anus. Nash reports as particularly indicating it a chronic sore throat of public speakers, with rawness in spots and a broken-down appearance, as if about to ulcerate, and this additional condition—"it hurts the patient to speak." Haemorrhages occur, dark and persistent. Swallowing is impossible or = severe cutting pains. Thought of food = retching. There are varicose veins with great tenderness on left leg. Symptoms are < after eating.
