back Ferrum Metallicum

Synonym. - Ferrum Metallicum. Preparation. - Tritura tions of pure Iron reduced by Hydrogen.


Ferrum acts pre-eminently upon the blood in such a manner as to produce a debilitating and disorganizing effect upon the entire system, the nutrition being profoundly affected. It at first and for a short time only vitalizes the blood and increases the red corpuscles, but soon the watery portions of the blood are increased, the albumen is decreased, and the number of red corpuscles diminished, this being accomplished through the influence of Iron on the blood-making organs, the result being that condition known as anaemia in the treatment of which Iron constitutes the most important remedy. The beneficial effects of Iron in anaemic states, how r ever, are not due to the fact that it is supplied as a food to the blood w^hich is deficient in this constituent; for, as Hughes truly remarks, u the malady does not ordinarily arise from any failure in the quantity of Iron supplied in the food. If the element is deficient in the blood, the fault lies in the assimilative processes. But Reveil has ascertained that in anaemia there is no change whatever in the amount of Iron present in the blood. However few the corpuscles, they contain within them the full proportion of the metal normal to health; and though under the influence of Iron itself they increase to double and triple their number, they yield no more Iron." It is also true that when Iron is introduced into the system in large quantities, with a view to supplying the deficiency of Iron in the blood, that it is not assimilated, but may be almost entirely re-obtained from the faeces, having been eliminated by the intestines. It is also true that the immediate primary effects of Iron are to increase the red blood corpuscles, as before noted, but its continued use results in exactly the opposite condition. It is thus evident that Iron does not act as a curative agent by virtue of its absorption as a constituent of the blood, but rather are we led to conclude, from its physiological effects upon the organs and tissues of the body, that it owes its therapeutic virtues to the same essential dynamic agency possessed by other drugs, and its application is subject to the same therapeutic law.

Iron is undoubtedly often the true homoeopathic remedy in anaemia (see General Analysis); but it is not the only remedy, and should never be prescribed unless the symptoms indicating it are present. There is always a sort of nervous erethistic condition present if Iron is the remedy. It is never indicated in anaemia characterized by a torpid, sluggish condition. Though there is great weakness, and the patients cannot endure the slightest excitement or fatigue, yet they cannot keep quiet and are better from very gentle exercise. The face is of a pale earthy hue, but flushes very easily; there are frequent attacks of severe headache, the head is inclined to be hot and the extremities cold, and the hands and feet are often oedematous. The patient is very easily excited, is sensitive to cold air and cannot endure pain. Often there is palpitation of the heart, with a well-marked bellows murmur. Iron is an exceptionally valuable remedy in erethistic chlorosis with the above symptoms, and in addition there is usually a milky, acrid leucorrhoea, and pale, watery menses, with lumps of blood, and attended with labor-like pains in the abdomen; also gastric symptoms, especially nausea after eating, or about midnight. Sometimes the menses are suppressed, and vicarious discharges of blood occur from other parts, especially the nose or lungs. Sometimes a remedy for menorrhagia in anaemic subjects. Haemorrhage from the uterus, with labor-like pains in the uterus, and glowing heat in the face; also the consequent anaemia. Headache after menses, with hot head and cold feet. Iron is frequently a valuable remedy in haemoptysis occurring in phthisis, especially in young people who are in the incipient stage of phthisis florida, flying pains in the chest; patients flush easily and get epistaxis, dyspnoea and palpitation; cough spasmodic from tickling in the larynx; thW, frothy expectoration streaked with brighfc-red blood; later the expectoration may be purulent and greenish. According to T. F. Allen, Ferrum is "extremely useful when the chest symptoms seem to occur from a kind ot surging of blood to the chest- a not infrequent symptom in persons whose circulation is feeble; in such cases there are oppression and dyspnoea. It has been prescribed for asthma and even for pneumonia, and it is very probable that Ferrum has been overlooked as a valuable remedy for inflammation of the thoracic organs, for it certainly may be indicated when there is marked febrile excitement." Iron undoubtedly produces true febrile paroxysms, and may be indicated in fevers, especially intermittents, when the foregoing symptoms of prostration are present, and when there is a profuse, clammy debilitating sweat; especially after the abuse of quinine, with enlarged spleen, anaemia, and dropsical swellings of the extremities. Ferrum is often a valuable remedy in chronic diarrhoea, with anaemic symptoms, and in the diarrhoeas which accompany phthisis and other exhausting diseases. The stools are painless, watery, sometimes containing undigested food, and always brought on by taking any food or drink. Sometimes useful in the diarrhoea of teething children; also with vomiting, which too is worse after food, drink or nursing. The drug is also useful in the dyspepsia of anaemic patients; usually a voracious appetite, or else the patient feels full and has no appetite; considerable flatulence; cannot eat, because it produces vomiting and sometimes diarrhoea. Bleeding haemorrhoids. Ascarides. Enuresis; both day and night, in children. Bright's disease. Violent neuralgias, with anaemia and characteristic symptoms, always better from moving slowly; pains usually throbbing. Paralysis. Exophthalmic goitre. Sometimes useful in lumbago and rheumatism, especially of the shoulders and lower limbs; better from walking about slowly.
