Below are the main rubriks (i.e strongest indications or symptoms) of Calc phos in traditional homeopathic usage, not approved by the FDA.
Have you ever used Calc phos? Yes No
Tardy closing or re-opening fontanelles in slim, emaciated children, with sweaty heads.
Diarrhoea or entero-colitis; stool passes with much flatulence and spluttering noise.
Rheumatic troubles which are worse in fall or spring, when the air is full of melting snow.
When on the subject of Calc Carb Calcarea we may as well notice this other combination.
The Phosphorus Phosphorus element in this preparation seems to change the temperament, for while it retains its wonderful remedial power over tardy bone development it acts best in spare subjects instead of fat. So that if we find a sickly child with fontanelles remaining open too long or re-opening after once closed, the child being spare and anaemic, we think of Calcarea Phosphorica.
We would also think of Silicea Silicea in one of these poor subjects, but in the Calc Carb Calcarea Phosphorus phos. the sweaty head is not a prominent symptom, while with Silicea Silicea it is markedly so. Calc Carb Calcarea Phosphorus phos; also has a very peculiar desire, the little patient instead of wanting eggs wants "ham rind," a very queer symptom, but a genuine one. (Magnesia carb. craves meat in scrofulous children.) Diarrhoea is very prominent, and the stools are green and "spluttering;" that is the flatulence (of which there is much) with the stool makes a loud spluttering noise when the stool passes. I have made some very fine cures in such cases where there seemed little hope for the child and hydrocephaloid seemed impending. The little patients were shrunken, emaciated and very anaemic. Marasmus.
