Calcarea Sulphurica (Calc. Sulph.), one of the twelve Schussler tissue salts, is a powerful remedy for chronic suppuration, pus formation, and wound healing.
It plays a crucial role in blood purification, skin health, and tissue repair.
Dr. Wilhelm Heinrich Schussler introduced this salt as an essential mineral for clearing infections, promoting drainage, and supporting the body’s natural healing processes.
This salt is primarily found in liver cells and connective tissues, where it helps remove waste products from the blood.
It is often compared to Hepar Sulphuris Calcareum, but it works more on chronic conditions rather than acute ones.
