Fe2(PO4)2. This salt is insoluble: the lower attenuations must therefore be triturations, above 12x dilutions.
FERRUM PHOSPHORICUM has the general characteristics of ferrum metallicum but the combination of phosphorous with the iron give it a symptomatology in some respects different. The difference are in the direction of making it more definitely inflammatory than ferrum, in increasing the tendency to haemorrhages, which are of a bright red colour, and in giving it wider and intenser action on the respiratory system.
It has accordingly acquired a reputation as a remedy for the first stage of inflammatory diseases before exudation has taken place. In these conditions it takes a place midway between the sthenic fevers of aconite and the low fevers of gelsemium. If a mucous membrane is the s34eat if an inflammation the fact that the discharge is blood-streaked would make one think of ferrum phosphoricum. Thus it is indicated in the watery blood-tinged stools, without tenesmus of acute diarrhoea and cholera infantum; in the first stage of pneumonia before consolidation, when the expectoration is streaked with blood; in pleurisy with high fever, dry cough and rapid pulse; in acute bronchitis and in common coryza. The rapid pulse and bloody discharges are the indicating features. The pulse is less tense than that of aconite and more tense than that of gelsemium. It has been useful in otitis and mastoiditis.
The hyperaemic headaches associated with the menses come before and not after the period, as is the case with ferrum.
(1) First stage of inflammations with blood-streaked discharges.
(2) Rapidity of pulse and high temperature.
(3) Anaemic, fair, florid, emotional people.
Generally the same as those of ferrum, but rest relieves more and moving slowly about relieves less and the midnight aggravation is less marked.
