Know Your Remedies: Calcarea Phosphorica (Calc-p.) 2

Common Name: Calcium phosphate.

General Information

Calcarea Phosphorica (Calc-p.) is a remedy for poor absorption and assimilation. Physical problems often involve joints, bones, teeth, and digestion. There may be lack of energy and mental or physical weakness or collapse. Obesity with flabbiness is common and symptoms may also worsen before or at the beginning of menses. Wet weather, cold air, drafts, and melting snow trigger headaches or joint and muscle pains. Bad news may lead to health complaints.

Children are irritable, whiny, easily bored, badly behaved, or want constant attention. The stresses of school may result in phobias, headaches and abdominal pain. Growing pains is another common symptom. The fontanelles (gaps between the bones of the head) of babies and infants may be slow to close, and walking and talking delayed. Growth may be rapid or delayed or stunted.

Guidelines on which potency to use

From Past Masters

Homeopathy is a 200-year system of medicine. Early medical homeopaths recorded initial provings, remedy relationships, and their early experiences with each remedy in great detail.

These writings were then shared with others to advance homeopathic knowledge and practice.

Today, these same writings give a fascinating insight into the symptoms and clinical conditions for which each remedy was used.

The following extract, with minor editing, is one example.

Leaders In Homoeopathic Therapeutics by E. B. NASH M.D.

Calcarea Phosphorica (Calc-p.)

I once had a case like this: A boy eight years of age had several (four or five) abscesses in and around the knee joint. The ulceration had also attacked the tibia, which was half eaten off, so that the ragged necrosed bone protruded through the surface plainly in sight.

The little fellow was greatly emaciated, and had no appetite, and was pale as a corpse. I told the mother that I thought this was a case for the surgeon, but I would try to get him in better condition for the operation. I remembered reading years before of the cures of abscesses by this remedy, made by Dr. Searles, of Albany, and empirically concluded to try it in this case.

I put him upon the first trituration, a grain a day. Called in a week and found a great change for the better. The mother exclaimed as I came in: “Ah, Doctor, the boys is eating us out of house and home.” Under the continued use of the remedy he made a complete and rapid recovery, except that the tibia was a little bent.

I have since used the remedy in some very large swellings where pus had formed, with the effect of complete absorption of the pus and no opening of the abscess on the surface. One was a case of hip disease which had been pronounced incurable by a specialist on ulcerations, (How is that for a specialist, regular at that.)

The different combinations of the Calcareas ought to be so thoroughly proven as to enable us to put them each in their exact place. So, also, with the Kalis, Magnesias, Natrums and Mercuries, etc.
