Ferrum Phosphoricum


James Tyler Kent describes the symptoms of the homeopathic medicine Ferrum Phosphoricum in great detail and compares it with other homeopathy remedies. …


Great weakness, and desire to lie down. Nervous at night. Rheumatic conditions.

While it has been used by Schuessler’s followers for the first stage of inflammatory fevers, it is useful in the higher potencies in chronic diseases, and is a deep acting anti-psoric, It could not be less than the Ferrum and Phosphoric acid that form it.

For many years I followed the Schüessler indications, but by the aid of new provings, homeopathic aggravations, and clinical experience the present arrangement of symptoms furnishes my guide for this valuable homoeopathic remedy.

The time of aggravation: of some complaints is in the morning, some in afternoon; others come in the evening and night, and after midnight. The patient is sensitive to the open air, and many symptoms are aggravated in open air.

The most noticeable features are anaemia and chlorosis (like Ferrum). The general physical anxiety is more like Phosphorus acid. Lack of vital heat, and aggravation in cold air and from becoming cold. Always taking cold. Congestion of head and organs, with fever and red face.

The general weakness is like the low vitality of the phtisical inheritance. Dropsical conditions. Symptoms worse after eating, from physical exertion. Fainting spells. Cold drinks bring on symptoms. Sour food aggravates. Vascular fullness and distension of veins.

The haemorrhagic condition is a strong feature, as it is in Ferrum, Phosphorus acid and Phos. The nervousness of hysteria and hypochondriasis is found in this remedy. Soreness through the body, especially in congested parts; with aggravation from jar and walking. Complaints from lifting and straining muscles, and from sprains.

Many symptoms are worse lying in bed and from rest, and ameliorated by moving slowly about (like Ferrum), but the great lassitude compels him to lie down. Motion that is a real exertion aggravates, but slow. motion ameliorates. Numbness of parts and suffering parts. Surging of blood in body and head.

Stitching, tearing pains. Tearing downwards. False plethora. Strong pulsation over body, and in head. Strong, full, frequent pulse. Generally oversensitive, and sensitive to pain. Standing aggravates many complaints. Trembling limbs. All combine to give us a remedy broad and deep acting.
