Ferrum phosphoricum makes up hemoglobin that carries oxygen throughout the body. It is thus commonly prescribed to treat fatigue and anemia (clinically evidenced by positive blood tests as well as sub-clinically when blood tests are negative but fatigue and weakness are significant), and to reduce hemorrhages (nose bleeds, excessive menstrual flow, and wounds).
Note that Ferrum phos cell salts do not cause constipation as many iron supplements do.
This cell salt is also typically given during the early stages of fever and inflammation or when one feels a cold or flu coming on in conjunction with being tired and run down. In fact, a Philadelphia homeopath, Dr. Garth Boericke, once described Ferrum phos as “the children’s antibiotic,” and suggested prescribing it immediately in cases of fever, coughing, and congestion.
