Characteristics
Outside homoeopathy Flint as an internal remedy is practically unknown. Hahnemann introduced it into medicine, and it was his method of attenuating insoluble substances that enabled him to discover its powers. *Silica forms one of the most important remedies of the *Chronic Diseases. A large proportion of the earth’s crust is composed of *Silica. Sea sand (*Silica marina) is mainly composed of it. The spicules of many sponges are made up of *Silica. Silicates are taken up by plants and from them *Silica is often deposited on the surface or in the interior of their stems. The strength of straw is due to *Silica. *Equisetum generally contains as much as 18 per cent. of *Silica to the fresh plant. Flint supplies the “grit” of the earth’s crust, of plant life, and to a large extent of animal life also. “Want of grit, moral or physical,” is a leading indication for *Silicea in homoeopathic practice. Teste puts *Silicea in his *Pulsatilla group of remedies, the other members of it being *Calcarea, *Help., *Graphites, *Pho. According to Teste, *Silicea is the “chronic” of *Pulsatilla, it corresponds to the chronic form of such diseases as *Pulsatilla cures when acute: Rush of blood to the head, especially to the right temple and vertex, headache every day, photophobia, lachrymation, loss of taste, aversion to fat food with rancid or oily taste in mouth, etc. The symptoms of *Silicea differ from those of *Pulsatilla in being more constant, more deep-seated, and lasting longer, for instance, the mucous secretions of *Pulsatilla become easily purulent under the action of *Silicea Teste points out that *Pulsatilla flourishes best on sandy soils (as *Belladonna does on calcareous soils). Schussler, who was a homoeopathist before he was a Biochemist, describes the sphere of *Silicea from the Tissue- Remedy point of view as follows: *”Silicic Acid is a constituent of the cells of the connective tissue, or the epidermis, the hair and the nails. If a suppurative center is formed either in the connective tissue or in a portion of the skin, *Silicea may be used.- After the functional ability of the cells of the connective tissue, which had been impaired by the pressure of the pus, has been restored to its integrity through a supply of molecules of *Silicea, these cells are thereby enabled to throw off inimical substances (the pus). In consequences, the pus is either absorbed by the lymphatics or it is cast out. In the latter case there is a so-called spontaneous breaking open of the suppurative center. – *Silicea may also cause the absorption through the lymphatics of an effusion of blood in any tissue. If the reabsorption of a sero-albuminous exudation in a serous sac cannot be effected through *Calcarea *phos., then *Silicea may be used, for the delay in the absorption may also be caused by a deficiency of Silicea in the subserous connective tissue. – *Silicea will also cure chronic arthritic-rheumatic affections, as it forms a soluble combination (*Sodium silicate) with the soda of the urate of soda, this combination is then absorbed and removed through the lymphatics. For the same reason it may also be used in renal gravel. -*Silicea can also restore the perspiration of the feet when this has been suppressed, and is thus an indirect remedy in diseases arising in consequence of such suppression (e.g., amblyopia, cataract, paralysis, etc.). – When a number of cells in the connective tissue are gradually deprived of *Silicea, they become atrophied. Such a disease is by no means rare in the external meatus auditorius with old people. The meatus in such a case is dry and enlarged.” (Schussler adds that he generally gives the 12X trituration.) The indications of Schussler correspond so exactly with those already pointed out by Hahnemann that we are left in doubt as to how much he was indebted to Hahnemann for his facts and how much to his own theories. Be that as it may, the relation of *Silicea to the connective tissues is a very real one. *Silicea is a great *evacuant. *Silicea produced in the provings sensation of “splinter in the finger,” of “a pin in the throat,” and whenever foreign bodies have become embedded in the tissues, or whenever portions of the tissues have become necrosed and quasi-foreign, *Silicea will set up suppuration in the vicinity and bring about their expulsion. (It is this property which makes it necessary sometimes to use Silicea with caution, if there are deposits which have become encysted and so far rendered harmless, the administration of *Silicea might set up suppurative action, to the risk of the patient’s life.) *Silicea both matures abscesses and reduced excessive suppuration. It will also resolve indurations left after suppuration, this has been particularly noted in the case of tonsils which refuse to heal after the pus has been evacuated, and in abscesses which leave sinuses and fistulae. *Silicea affects the nails, cripples them, and produces inflammation around and under them. “Sensation as if the finger-tips were suppurating” is one of the symptoms which led to its use in such cases. *Silicea causes inflammation, swelling and suppuration of all the lymphatic glands and also the glands of the skin. The skin is unhealthy and every little injury ulcerates. Hands and feet are sweaty, and the sweat is generally offensive. The feet may give off an intolerable odour without any sweat. The head sweats, and this may be offensive. *Silicea corresponds perfectly to many cases of rickets: children with large heads, open fontanelles and sutures, much sweating about the head, which must be kept warm, distended abdomen, weak ankles, slow in learning to walk. This constitutes type No. 1, to which *Silicea is *particularly suited. It is also *suited to: (2) Nervous, irritable persons, with dry skin, profuse saliva, diarrhoea, night-sweats. (3) Weakly persons, fine skin, pale face, light complexion, lax muscles. (4) Constitutions which suffer from deficient nutrition due to lack of assimilating power, oversensitive physically and mentally. (5) Scrofulous children who have worm diseases during dentition. (6) Stonecutters’ ailments (chest affections and total loss of strength. The action of *Silicea on the connective tissues may end in new growth as well as in suppuration and ulceration. It has a specific relation to scarred tissue, and I have cured with it a case of recurrent cheloid: Eleanor W., 14, had a growth on left temple. Five months before she had been an inmate in St. Bartholomew’s Hospital and had a tumour removed from the spot, the tumour having existed for two years. A month after the operation a new growth appeared on the scar. Two months later this was removed. But it rapidly recurred, and when I saw her there was a linear elevation an inch long, three lines wide, and raised about two lines. It was red, shiny, and slightly modulated, was *tender to touch and the seat of *shooting pain. Before the first operation there had been no pain and no discoloration of the skin. Hahnemann gives this symptom in the proving of *Silicea “Stitching, aching pain in the spot where an ulcer had been formerly on the leg.” *Silicea 3 gr. iii., night and morning, was prescribed. There was no further increase in the size of the growth, though it was still painful, the pain being apparently somewhat increased. In three months there was evident diminution in size, and from that time the pain began to diminish. In seven months the growth had entirely disappeared.- The sensitiveness of *Silicea is one of its keynotes, and an over- susceptibility to nervous stimuli is a frequent accompaniment of conditions requiring *Silicea The surface is tender and the least touch is painful. The senses are morbidly keen. Brain and spine cannot bear even ordinary vibrations. This condition may be caused by losses of fluids as in spermatorrhoea, by over-worked brain. *Silicea causes tendency to paralysis and paralytic weakness from defective nutrition of nerves of brain and spinal cord. Constipation is often an accompaniment of these conditions. There may be epileptic convulsions. These have a well-marked course, starting from the solar plexus, are worse at full and new moon, and worse from any overstrain of mind or emotions. *Silicea is indicated in locomotor ataxy when the fingers feel stiff with loss of power in them. There is spinal irritation. The neck is stiff causing headache. The small of the back aches as if beaten. The part of the body lain on goes to sleep. The headaches of *Silicea present one of the grand characteristics of the remedy. They are of the chronic kind, and may owe their origin to some severe disease of youth. They ascend from the nape of the neck to the vertex, as if coming from the spine, and locate in one eye, especially the right, worse from draught of air or uncovering head, better pressure and *wrapping head up warmly, better profuse urination. The vertigo of *Silicea in the same way ascends from the back of the neck, as if one would fall forward (sometimes backward), worse looking up, closing eyes, lying on left side. The sensitiveness of *Silicea comes out in the mental symptoms: “Sensitive to noise, and anxiety therefrom.” “Sensitive, weeping mood.” “Yielding, faint-hearted.” “Children become obstinate, headstrong, cry when kindly spoken to.” A curious symptom and one of great value is this: “Fixed ideas: the patient thinks only of pins, fears them, searches for them, and counts them carefully.” This symptom enabled me to make a rapid cure of post-influenzal insanity in the case of a man of bad family history, one of whose sisters had become insane and had drowned herself, another sister being affected with lupus. The patient’s wife told me one morning that he had *”been looking everywhere for pins.” *Silicea 30 rapidly put an end to the search and restored the patient to his senses. *Silicea has another link with insanity in its aggravation at the moon’s phases: epilepsy and sleep-walking are worse at the new and full moon. The *Silicea patient likes to be magnetized, and is better by it. This is related to the persistent want of vital heat which characterizes the *Silicea condition, even exercise will not get up any warmth. Another curious symptom of *Silicea is: “Discharge of blood from the vagina every time the child takes the breast.” Another symptom in this relation is important in connection with cancer cases: “nipple is drawn in like a funnel.” Always before and during menses there is constipation. The constipation of *Silicea is characteristic. The stool is difficult as from inactivity of rectum, with great straining as if rectum was paralysed, *when partly expelled recedes again. Faeces remain a long time in rectum. Rushmore (H. P., xii. 530) verified a peculiar symptom of *Silicea in a lady suffering from scirrhus of left breast. She had a feeling of dryness in her *finger-tips, *as if made of paper, *at night. *Ant. *t. and *Silicea have this symptom, but only *Silicea in afternoon. *Silicea removed this and took away sharp, stinging pains in the tumour as well. *Peculiar Sensations of *Silicea are: Susceptibility to nervous stimuli, to magnetism.As if she would die. As if gradually losing senses. As if feeling for pins. Sensation as if she were divided into halves and that the left side does not belong to her. As if one would fall forward. Vertigo as if drunk. As if head were teeming with live things whirling around in it. Headache as if beaten. As if everything would press out and burst skull. As if brain and eyes were forced forward. As if head would burst with throbbing in it, internal and external at same time. As if forehead would be torn asunder, as from a heavy weight over eyes. As if head were forced asunder. As of water-pipes bursting in head. As if tremendous weight were falling on vertex. Head as if in a cushion and some one were pressing two fingers into it at occiput. As if brain collided with skull. Head as if bruised. As if waves of water from occiput over vertex to forehead. Sick-headaches as if coming from spine and locating over one eye. Head as if too large. As if head were falling off, as if it were hanging by a piece of skin at nape. As if right side of head paralysed. As if looking through a grey cover.

As if sternum were grasped. As of a stone under sternum. As if mould were forming over whole body. As if a hand had grasped her breastbone. Cords of neck as if pulled. Small of back as if beaten, as if dead. Arms and hands as if filled with lead. As of a splinter in finger. As if a panaritium would form in index finger. As if tips of fingers were suppurating. As if finger were thick and bone enlarged. As if joints of fingers were being pulled out of sockets. Limbs and feet as if paralysed. Femur as if beaten. Knees as if too tightly bound. Calves as if too short. As if spasms in ankles. As if toe-joints being pulled out of sockets. Nails as if decayed. As if beaten all over. As if he had lain in an uncomfortable position. The direction of the *Silicea action is upward and *outward: there are shooting out through eyes and out of ears. The symptoms are: worse By touch, contact, combing hair. Binding tightly better headache, but pressure of hat causes pain. Pressure worse. Rest better. Motion worse. Lying down worse asthma, causes headache. Lying right side worse pains in liver. Lying left side causes vertigo. Sitting worse. Gaping or swallowing better stoppage of ear. Opening eyes worse pressive pain. Writing causes tonic spasm of hand. Walking worse, every step is painfully felt (incarcerated flatus). Open-air worse headache, causes lachrymation, burning in back. Cold air (especially on head, eyes, back of neck, back), cold draft, changing linen, uncovering worse. Worse washing. Change of weather worse pain in ears, worse pain in limbs. Worse before and during a storm. Better summer. Worse approach of winter. Worse at new moon, increasing moon (hysteria), and full moon. Better In warm room, by warm wraps. Worse mental exertion, talking. Pain in head better while eating. Worse after eating. Milk worse, causes diarrhoea. Aversion to mother’s milk and vomiting whenever taking it.
