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

Calcarea Carbonica, from oyster shell, is a great constitutional picture of chilly, easily-tired people with a sluggish, slow-and-steady metabolism. Sweating of the head, especially during sleep, is characteristic, along with a craving for eggs and indigestible things, anxiety about health, and a tendency to feel overwhelmed when overworked. Bone, teeth and joint complaints and recurrent infections, particularly in children, fit the pattern, and symptoms are typically worse from cold, damp and exertion. This is a recognisable constitutional tendency suiting only some people, not a diagnosis of any condition.

Before you take Calcarea Carbonica

Calc Carb is a deep constitutional remedy, and the right medicine and potency are matched to the whole individual by a qualified homeopath rather than selected from symptoms. This page provides background on the picture; it is not a prescription and does not tell you to self-choose a potency. Thyroid, metabolic or recurrent infective complaints need medical monitoring alongside, and any severe or lasting symptoms deserve proper assessment. Please consult a registered practitioner before taking anything, and continue any care your own doctor has already arranged.
