This is general information about a homeopathic remedy, not a prescription or dosing advice. In homeopathy the correct remedy and potency are chosen for the whole individual symptom picture by a qualified homeopath — the same remedy is not right for everyone. Do not self-medicate, and consult a qualified homeopathic doctor (and your physician for serious or persistent conditions) before taking any remedy.

The characteristic picture & modalities

Silicea, prepared from flint, is a deep constitutional picture of poor stamina, slow healing and recurrent pus-forming infections in a refined, mild, yielding and sensitive person who lacks grit. The individual is chilly, often with offensive sweat, especially of the feet, and a tendency to suppuration, recurrent colds, boils and styes. Weak, brittle nails and hair and a bashful, receding stool can feature, with symptoms worse from cold, damp and exertion. This is a recognisable constitutional tendency that suits only some people, describing a pattern rather than any diagnosis.

Before you take Silicea

Silicea is a deep constitutional remedy, and the right medicine and potency are matched to the whole person by a qualified homeopath, not chosen from a symptom list. This page is background on the picture, not a prescription, and it does not invite you to self-select a potency. Spreading infection, a fever, or any slow-healing wound that worsens needs medical care, and persistent or severe symptoms deserve proper assessment. Please consult a registered practitioner before taking anything, and keep any treatment your own doctor has advised.
