Cyanide of Mercury
Acute infections, pneumonia, nephritis. Its action is similar to that of the toxines of infections diseases. Great and rapid prostration, tendency toward haemorrhages, from the different orifices, of dark fluid blood, cyanosis, rapid respiration and heart action, albuminuria and twitching and jerking of muscles. Typhoid pneumonia.
Livid states from great struggling, where suffocation is imminent and paralysis of lung threatening; great sweat.
Affects most prominently the buccal cavity. This, together with marked prostration, gives it a place in the treatment of diphtheria, where it has achieved unquestioned great results. Malignant types, with prostration. Coldness and nausea. Syphilitic ulcers when perforation threatens.
Head.--Great excitement, fits of passion; fury; talkativeness. Atrocious headache. Eyes sunken; face pale.
Mouth.--Covered with ulcerations. Tongue pale. Free salivation. Fetor of breath. Pain and swelling of salivary glands. Astringent taste. Ulcerations of mouth have a gray membrane.
Throat.--Feels raw and sore. Mucous membranes broken down, ulcerated. Looks raw in spots, especially in public speakers. Hoarseness, and talking is painful. Necrotic destruction of soft parts of palate and fauces. Intense redness of fauces. Swallowing very difficult. Dark blood from nose. Diphtheria of the larynx and nose (Kali bich).
Stomach.--Nausea, vomiting, bilious, bloody; hiccough; abdomen painful, tender to pressure.
Rectum.--Intolerable pain. Redness around anus. Frequent haemorrhage; stools with tenesmus. Discharge of fetid liquid with gangrenous odor. Black stools.
Urinary.--Amber color, painful, albuminous, scanty. Nephritis with great debility and chilliness. Suppression of urine.
Skin.--Moisture, with icy coldness.
Dose.--Sixth to thirtieth potency. Aggravation is apt to occur from potencies below the sixth.
Lectures on Homoeopathic Materia Medica, James Tyler Kent
Given a Merc. base and diphtheria, when the membrane is greenish and inclined to spread through the nose and involve a large surface, the Cyanide of Mercury is needed.
It has exudation more marked than any other form of Mercury.
Malignant forms of diphtheria, rapidly forming, and with phagedenic ulceration.
A Dictionary of Practical Materia Medica, John Henry Clarke
Bicyanide of Mercury. Mercuric Cyanide. Hg (CN)2. Solution. Trituration.
Clinical.─Diphtheria. Dysentery. Enteric fever. Haemorrhages. Kerato-iritis syphilitica. Phlebitis. Throat, sore. Varicosis.
Characteristics.─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.

Cyanide of Mercury (Hg(CN2))
Malignant diphtheria with intense redness of fauces and great difficulty of swallowing; pseudo-membranous formation extends all over fauces and down throat; putrid, gangrenous diphtheria, with phagedenic ulceration; membranous croup. Great weakness; extreme prostration; cannot stand up from weakness. When it corresponds to the genus epidemicus, like every other remedy, is effective as a prophylactic.
Leaders In Homoeopathic Therapeutics, Eugene Beauharnais Nash
Dr. Beck, of Monthey, in Switzerland (I think it was), first brought this remedy to notice as of great value in that much-dreaded disease, diphtheria. Von Villiers claimed to have had astonishing success with it in Germany, losing only two per cent. (if I remember correctly) of the cases treated With it. He recommended the 30th potency, but others have used the 6th and claim equally good results. There are, so far as I can find, no very marked characteristic symptoms by which to choose it. It seems to spread its action all over the buccal cavity. Dr. T. F. Allen published a good cure with it, and then claimed that he chose this preparation of Mercury on account of the remarkable prostration, which he attributed to the cyanogen element in it. This looks reasonable. But I think we must investigate further to bring out its true characteristics. There is a chronic condition of the throat in which I have found it very efficacious. It is in the so-called cases of public speakers. The throat feels raw and sore, and examination reveals a broken down appearance of the mucous membrane bordering on ulceration. It is nor granulated, but looks raw in spots, as if denuded of membrane. I have helped this kind of throat, so that the patient wanted me to remember what it was I gave him so that I could repeat the prescription if the trouble returned. I forgot to state that it hurt the patient to speak, and there was also hoarseness. This is all I know of this remedy, but I believe it well worth proving and study.
