Silica may be used as a Homeopathic or used simply as a micro-nutritional (mineral; tissue salt). Homeopathic potencies accredit their strength and efficacy to the electromagnetic signatures of the original substrate; these are scientifically created dilutions and succussions of medicines such that generally not even a molecule of the original substrate or medicine is present in the medicine. Silica is also known as quartz.

As a Homeopathic or used simply as a micro-nutritional, Silica has demonstrated effectiveness against the following symptomology: "...useful in suppurative processes which involve the bones, periosteum and soft tissues; also involvement of the glands when suppuration is present, and when small wounds do not heal readily and are prone to suppurate...the skin is sensitive and irritable and the whole body is sensitive as if beaten." (Blackwood) -"Diseases of bones, caries and necrosis; can stimulate system to reabsorb fibrotic conditions and scar tissue; keloid growth; ill effects of vaccination; fistula; colds fail to yield; slow recovery after pneumonia; hard lumps in breasts; weak spine, spinal irritation after injuries to spine; diseases of bones of spine; crippled nails; indurated tumors; ulcers of skin; promotes expulsion of foreign bodies from tissues..." (Boericke)

Silica has also demonstrated effectiveness against the following symptomology: weakness of connective tissue, rickets; TB of hilar and mesenteric glands; -disorders of nutrition...and failure to thrive; painless glandular swellings; -thin, acrid discharges; suppurative fistulae in otitis media, anal fistulae, surgical wounds, etc; skin slow to heal; -general chilliness and sensitivity to cold air...sour sweating of head and feet; -nervous irritation and timidity; indecision, acquiescence, lack of courage; -pustular skin eruptions, urticaria, acne vulgaris, pruritus, hyperesthesia of skin to touch (Reckeweg) "Useful in chronic bronchitis when there is a deep seated organic cause...useful in emphysema when suppuration is chronic...useful during suppurating stages of pulmonary TB with...hectic fever, emaciation, weakness and debilitating night sweats." (Blackwood)

Further Silica helps with -"Imperfect assimilation and consequent defective nutrition... neurasthenic states and increased susceptibility to nervous stimuli and exaggerated reflexes; disease of bones, caries and necrosis...periodical states: abscesses, quinsy, headaches, spasms, epilepsy...ill effects of vaccination...suppurative processes...lack of vital heat; prostration of mind and body; great sensitiveness to taking (ie, catching) cold: colds fail to yield; slow recovery...chilliness, very sensitive to cold air, creeping shivering over whole body, cold extremities even in a warm room, sweat at night..." (Boericke)

More symptoms Silica effects include: -Rush of blood to head, great sensitiveness of the hair, perspiration of head, pains running from neck up into head, paroxysms end with profuse urination; -headache every seventh day; -violent periodic hemicrania, vertex, occiput or forehead, often with nausea to fainting and obscuration of sight; -worse from mental exertion, motion (even jarring of room by footsteps), stooping, talking, light, cold air, touch; -better from heat, lying down in the dark (Lilienthal) "Silica is one of our most valuable remedies in epilepsy... the aura starts from the solar plexus...nocturnal epilepsy, feeling of coldness before an attack is also characteristic, the fit is followed by warm perspiration...there is an exalted susceptibility of the upper spinal cord and the medulla and an exhausted condition of the nerves...coldness of the left side of the body preceding the attack is very characteristic;" (Dewey)

Silica also influences these feelings: -yielding, fainthearted, anxious, nervous and excitable, sensitive to all impressions; -sexual erethism, nocturnal emissions (men); -night-walking, gets up while asleep; sleeplessness with great orgasm (rush) of blood and heat in head, frequent starts in sleep, anxious dreams; -sciatica, pains through hips, legs and feet, cramp in calves and soles; loss of power in legs; -tremulous hands when using them; paralytic weakness of forearm (Boericke) "This remedy will often abate the pains of cancer...sarcoma with thick yellow and offensive discharge." (Dewey) -"Silica is eminently suited to so-called dyscrasias such as are found...in precancerous states." (Reckeweg).
