Ferrum phos. seems to me to stand midway between Aconite and Belladonna, for while it does not present the excitement and fear of Aconite, on the other hand it does not produce so strong brain symptoms as Belladonna. I have found it of most service in pale anaemic subjects, who are subject to flushes of heat and redness of the face, and to local congestions generally.
It certainly does fine work in such subjects in this stage of the disease. In regard to Pneumonia.
Chills followed by synochal fever, high temperature, quick pulse, general dry heat, dry skin. There is generally short dry cough. If such an attack should occur in a delicate, pale or weakly subject Ferrum phosphoricum would generally do good work. With Ferrum there is not so much of the nervous excitability as with Aconite, but the fever is very great and congestion to the lungs more liable if anything. Acute bronchitis.
