When used as a homeopathic remedy Silica becomes a simple and powerful medicine with a capacity in children and adults to help those who are prone to lingering infections for instance in the site of wounds and scars. Silica may also help the body to throw out splinters. It is used primarily to treat chronic conditions, although it can also be prescribed for more general problems, such as the common cold.
The remedy silica is derived from flint
Silica, also called silicea, is derived from quartz or flint and is a mineral present in the earth’s crust. Flint was used in the manufacture of tools during the Stone Age as it splits into thin, sharp splinters called flakes or blades (depending on the shape) when struck by another hard object (such as a hammerstone made of another material). When struck against steel, a flint edge will produce sparks.
The hard flint edge shaves off a particle of the steel that exposes iron which reacts with oxygen from the atmosphere and can ignite the tinder. Prior to the wide availability of steel, rocks of iron pyrite would be used along with the flint, in a similar (but more time-consuming) way. These methods are popular in woodcraft, bushcraft, and among those who wish to use traditional skills.
Silica is necessary in the human body
Silica is necessary for healthy and normal growth maintenance, human research has demonstrated the effects of silica on a broad spectrum of maladies from youth through middle and old age.
The necessity of silica for collagen formation and development is the basis of many of these physiological effects. Collagen is the tough fibrous material that holds us together. Many aging problems are a direct result of the body’s inability to maintain adequate collagen. Think for a moment about the following aging problems: joint deterioration, brittle bones, hardening of the arteries, dry skin, inability to digest food properly, weakened teeth and gums, and atrophying organs. They all are collagen related in one form or another. When we are young, Silica levels in our body are high and our bones and joints are flexible. Our skin is supple and glowing. As we age, Silica levels decline and without adequate tissue levels of Silica, we manifest many of the symptoms of aging such as joint disease, weakened digestion, and wrinkled skin, to name a few.
When used as a homeopathic remedy Silica has many uses
The person who will benefit from Silica is chilly; his symptoms are developed in cold, damp weather, though often better in cold, dry weather; symptoms come out after a bath. The symptoms listed below are straight from the materia medica - http://homeoint.org/books3/kentmm/sil.htm
Mind: The mental state is peculiar. The patient lacks stamina. What Silica is to the stalk of, grain in the field, it is to the human mind. Take the glossy, stiff, outer covering of a stalk of grain and examine it, and you will realize with what firmness it supports the head of grain until it ripens; there is a gradual deposit of Silica in it to give it stamina. So it is with the mind; when the mind needs Silica it is in a state of weakness, embarrassment, dread, a state of yielding.
If you should listen to the description of this state by a prominent clergyman, or a lawyer, or a man in the habit of appearing in public with self-confidence, firmness and fullness of thought and speech, he would tell you he had come to a state where he dreads to appear in public, he feels his own selfhood so that he cannot enter into his subject, he dreads it, he fears that he will fail, his mind will not work, he is worn out by prolonged efforts at mental work. But he will say that when he forces himself into the harness he can go on with ease, his usual self-command returns to him and he does well; he does his work with promptness, fullness, and accuracy. The peculiar Silica state is found in the dread of failure.
If he has any unusual mental task to perform, he fears he will make a failure of it, yet he does it well. This is the early state; of course there comes a time when he cannot perform the work with accuracy and still he may need Silica.
