🦪 Calcarea carbonica

In short: Calcarea carbonica is a homeopathic remedy classically matched to fatigue and chilliness; easy sweating, especially head at night; anxiety about health; weight gain tendency; slow, cautious personality; better in dry weather.. It is commonly used for fatigue & chilliness, night sweats, anxious, cautious type, usually in 6c, 30c dilutions. Evidence for specific effects is limited and debated, so it is best treated as a complement to conventional care — this is general information, not medical advice.

📜 History of the remedy

Calcarea carbonica — the middle layer of the oyster shell — was proved by Hahnemann in 1805 and became one of the great "constitutional" remedies: the picture of the chilly, cautious, easily-tired person who builds up slowly and steadily, like shell.

🧠 Mind & mood

Cautious, anxious and conscientious. The person worries about health and the future, hates change, and can become stubborn when pressed. Mental and physical work feel like an effort; they would rather sit and plan than act.

🔑 Key indications

• Fatigue and chilliness with easy sweating, especially the head at night
• Weight gain tendency with slow metabolism
• Anxiety about health and imagined illness
• Weak, brittle nails and hair; calcium-metabolism-type complaints
• Night sweats in children during sleep

↕️ Modalities (what makes it worse or better)

Worse: cold, damp air, exertion, standing, mental effort. Better: dry weather, lying on the affected side, after a nap.

💊 Dosage & repetition

6C or 30C. Constitutional use is usually one dose at 30C, repeated only after discussion with a practitioner — not daily low-potency repetition. Persistent fatigue, weight change or night sweats deserve a medical check-up first.

⚖️ Compare with

Compare with Silicea (chilly, anxious, but delicate and yielding rather than stubborn) and Lycopodium (digestive, worse 4-8pm, fearful of responsibility).
