Malignant and gangrenous inflammations. Enlarged suppurating glands, especially cervical glands. Neglected cases of injury if suppuration threatens. Discharges and excretions offensive. Dropsy.

Symptoms are always worse at night and during full moon. Amelioration by heal and warm room. Headache relieved by wrapping the head up warm. Abdominal pains, cough, rheumatic pains all relieved by warmth. Worse in the open air; worse from suppressed foot-sweat or chilling the feet or from cold.

Homoeopathic Data

This drug was proved by Hahnemann. The first record of it appeared in the Chronic Diseases, vol. iii, in 1828.


Schussler recommends the 6x and the i2x potencies, but in the homoeopathic school the most brilliant results have followed the use of the higher attenuations (see Clinical Cases, Part III). Its external application is also recommended by Schussler and others, in carbuncles, ulcers, ulceration of womb, abscess, ozaena as a spray, etc. Massive and repeated doses are indicated in scrofulous, glandular swellings without suppurations. But where there is actual suppuration, or even a tendency thereto, high potencies (30th) help in chronic cases, one dose daily, or even less often, in subacute cases, morning and evening - in acute cases from two to three hours. An effective method of using Silieea locally is to make a strong decoction of hay. This contains a large percentage of Silieea. The silicate of soda should be given in free solution. Percy Wilde, M. D., who introduced this valuable preparation of Silieea, gives three to four drops three times daily, and each dose is given in one-third of a tumbler of water, or, better still, in milk.

The effect of the remedy must be watched, as it is apt to cause active changes in the tumor within forty-eight hours (see Tumors, Part III).


In suppuration compare Calcarea sulph., the difference being that Silicea promotes suppuration and brings the process to maturity, whereas Calc. sulph, heals the process by checking it and promoting the healthy granulation. For results from impure vaccination we have, besides Silicea and Thuja, Kali mur., which, according to Schussler, is the one remedy necessary. The Silicea headache is similar to Spigel, Paris, Picric acid, CoccuL, Gelsem. and Sanguin. In fistula lachrymalis compare Natr. mur. and Petrol. In whitlow and ingrowing toe-nail, when Silicea fails, Graphit often succeeds. In caries and periostitis compare Asaf., Graphit., Conium, Platina mur. In tabes compare Alumina, Ruta. Silicea is a chronic Pulsat.; it corresponds to the chronic form of such diseases as Pulsat. cures when acute. Pulsat. grows on sandy bottom, and probably contains Silicea as one of its constituents. In bone diseases it resembles closely Mercur., but it should not be given after Mercur., as it may much complicate the case. (Gilchrist).

In Moleschott's Kreislauf des Lebens, he says that the ashes of EquiseL hyem. consist nearly wholly of Silicea. The cures of bladder troubles reported by Equiset. are probably due to the Silicea it contains. The mineral springs of Bareges, in the Pyrenees, contain an unusually large amount of Silicea in a soluble form, and this spa has been singled out by empirical experience as most valuable in the class of cases for which Silicea is homceopathically indicated. (Percy Wilde, M. D).

In labyrinthine vertigo compare Nalr. salicy. In ulceration around the nails, Psorinum is invaluable. Allied remedies: Fluoric acid. Picric acid, Hypericum, Ruta, Mercur., etc.
