Ferrum phosphoricum
Substance Background
Ferrum phosphoricum is a chemical combination of iron and phosphorus, generally prepared by mixing solutions of ferric chloride (FeCl₃) and sodium phosphate (Na₃POâ‚„), resulting in a fine, white amorphous powder. Its chemical formula is FePOâ‚„. It is considered a tissue salt and was introduced into homeopathy via Schüssler’s system of biochemic therapy.
Proving Information
No traditional Hahnemannian proving. Introduced by Dr. Wilhelm Heinrich Schüssler in the late 19th century through clinical observations and biochemical theory rather than classical provings. Confirmatory symptoms gathered from clinical experience and secondarily through Materia Medica sources like Boericke and Clarke.
Remedy Essence
Ferrum phosphoricum is a remedy of beginnings—it acts best in the incipient stages of inflammation, before full-blown pathology develops. The patient is often anaemic, sensitive, flushed yet weak, with vague and undeveloped symptoms. It suits delicate constitutions and children. A gentle, unassuming remedy that operates quietly but powerfully when the picture is unclear.
Affinity
Capillaries; blood vessels; respiratory tract; throat; mucous membranes; muscles; right-sided complaints; inflammation in the first stage; fever states.

Touch; jarring; heat; excitement; sun exposure; motion; noise.
Symptomatology
Mind
The Ferrum phosphoricum patient is often described as mild, gentle, and reserved, yet sensitive to surroundings and easily fatigued mentally. Boericke notes that the mind is sluggish, with difficulty concentrating, especially during febrile states. Clarke adds that they may become anxious, especially when symptoms rise suddenly, but not to the same degree as seen in more expressive remedies like Aconitum. There may be indifference or a dulled emotional response accompanying physical illness.
Head
Boericke describes frontal headaches with dullness and throbbing, particularly in the right temple, often appearing in the early stages of colds or fevers. Headaches are worse from motion or noise and better lying down. Head congestion is mild but persistent, especially in children during early infection phases. Clarke notes the head feels hot to the touch, although the patient does not complain of significant subjective heat.
