Silica. Silicea Tera. Silex. Decarbonized white pebble. Acidium Silicicum. The proper name is Silicic Oxide.

Common Names
Pure Flint or Quartz. Silicious Earth.

Chemical Properties
Formula, Si02. Prepared by fusing silica and carbonate of sodium; dissolving residue filtered and precipitated by hydrochloric acid. It is a white powder, having neither taste nor smell.

Pure Silicea is triturated according to the rules of the homcepathic pharmacopoeias. Dr. P. Wilde uses preferably the silicate of soda known as "liquid glass," which is freely soluble in water. (See "Administration.") Dr. J. J. Garth Wilkinson preferred the Silica obtained from the Bamboo. Found it better in acute conditions.

Physiologico-chemical Data
Although this inorganic salt is found very abundantly throughout the vegetable kingdom, especially in grasses, grain, palms, etc., it is found comparatively little in the animal kingdom, notably so in the higher orders, the vertebrae. Traces of Silicea, however, are found in the ashes of blood, bile or urine, and larger quantities (7 per cent.) in the white of egg, and even more in the ashes of the epidermis, hair and nails. It is also found in the connective tissue, especially embryonic, and hence its action on the spinal cord, brain and nerves must be referred to the investing membrane, the connective tissue, of the nerve-fibres. Disturbance of the function of the Silicea molecules causes a tumescence of the cells of the connective tissues involved. This swelling may remain stationary for a time, then disappear or occasion suppuration. Prof. Schultz, of Griefswald University, found this salt also in the lens, in pus and in ovarian cysts.

General Action
Silicea acts more upon the organic substances of the body, involving prominently bones, joints, glands, skin and mucous surfaces, producing malnutrition and corresponding to the scrofulous diathesis. Its action is deep and long-lasting. It is especially suited to imperfectly nourished constitutions, owing to deficient assimilation.
It is the remedy for ailments attended with pus-formation, and is closely related to all fistulous burrowings. Wherever pus is formed in an inflamed part of connective tissue or skin, Silicea may be used. Deeply-seated scrofulous cachexia and some forms of septic infections (vaccine) find in it a valuable general remedy. Like Calc. sulph., Silicea corresponds to the process of suppuration, with the following distinguishing features: Silicea ripens abscess, since it promotes suppuration. Calc. sulph., by restraining the suppurative process, heals suppurating wounds. As long as infiltration, which can only disappear by suppuration, lasts, Silicea is the remedy, and should be continued until all the infiltrated parts have disappeared. If then the wound fails to heal, give Calc. sulph. Ailments affecting the periosteum. Deep-seated suppurations, pus thick and yellow; also in certain reflex affections connected with the nerves. After suppuration has ceased to be active, but the process lingers and the pus forms chronic deposits, small or large, fistulous or otherwise; also, where the general organism is both irritable and weak, and the nervous system is easily aroused to exhausting agitation (as Dunham says, it is contraindicated by general nerve torpor), this is a specific remedy. In localized exhaustion, when the symptoms resemble paralysis—e. g., rectal distention, dilated and irritable heart, great general debility, as after lying-in—it should always be thought of. In general hyperesthesia and exaggerated reflexes.
Silicea has also the power to reabsorb a bloody or sero-albuminous exudate, existing within the tissues by means of the lymphatics. Here it often follows Calc. phos.
Silicea cures chronic gouty rheumatic affections by means of its stimulating effects of the involved connective tissue cells, compelling these to throw off the accumulated urates through the lymphatics.
Silicea can restore suppressed foot-sweats, and in this way be an indirect remedy for diseases resulting from suppression of foot-sweat, for instance: Amblyopia, cataract, paralysis, etc.
If the cells of any part of the connective tissue show a lack of Silicea molecules, they atrophy in consequence. The central and peripheral nervous system are definitely affected by Silicea, as seen in the languor, sleepiness, anxious dreams, nervous irritability, depression, headaches, trembling and paretic symptoms.

Homeopathic 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 12x potencies, but in the homeopathic 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 Silicea locally is to make a strong decoction of hay. This contains a large, percentage of Silicea. The silicate of soda should be given in free solution. Percy Wilde, M. D., who introduced this valuable preparation of Silicea, 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 Schtissler, 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 Silica 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.
In Moleschott's Kreislauf des Lebens, he says that the ashes of Equiset. hyem. consist nearly wholly of Silicea. The cures of bladder troubles reported by Equiset. are probably due to the Silica 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 homeopathically indicated. (Percy Wilde, M. D.) In labyrinthine vertigo compare Natr. salicy. In ulceration around the nails, Psorinum is invaluable. Allied remedies: Fluoric acid, Picric acid, Hypericum, Ruta, Mercur., etc.
