Do not self-medicate, and consult a qualified homeopathic doctor (and your physician for serious or persistent conditions) before taking any remedy.

Potency

Calcarea Sulphurica is available in several potencies such as 6C, 30C and 200C, and in lower or biochemic and mother-tincture forms in some cases. The right potency and repetition depend entirely on the individual case and are decided by a qualified homeopath - this page gives no dosing instructions.

The Calc Sulph picture and modalities

Calcarea Sulphurica belongs to the later stage of suppuration. Its keynote is thick, yellow, lumpy discharge from pimples, boils, and abscesses that are slow to heal once opened, as if pus keeps forming even though it has a way out. Eruptions linger and are slow to close. A homeopath weighs this yellow-discharge, slow-healing pattern within the whole picture rather than any single feature.

Before you consider Calc Sulph

This is background information, not advice to self-treat. Persistent or severe acne, a spreading or painful abscess, and any wound with signs of infection deserve medical assessment. In homeopathy the right remedy and potency are chosen for the whole individual by a qualified practitioner, and the same remedy is not right for everyone. Homeopathy should complement, not replace, conventional care.
