The Medicinal Virtue1 of Iron.93
N ot foreign to our present purpose will it be to treat briefly2 also of the medicinal virtue of iron: for it is a prime remedial for some diseases of the human body, and by its virtues3, both those that are natural and those acquired by suitable preparation, it works marvellous changes in the human body, so that we may the more surely recognize its nature through its medicinal virtue and through certain manifest experiments. So that even those tyros4 in medicine who abuse this most famous medicament may learn to prescribe it with better judgment5 for the healing of the sick, and not, as too often they use it, to their harm. The best iron, Stomoma, or Chalybs, Acies, or Aciarium, is reduced to a fine powder by a file; the powder is steeped in the sharpest vinegar, and dried in the sun, and again soused in vinegar, and dried; afterwards it is washed in spring water or other suitable water, and dried; then for the second time it is pulverized6 and reduced on porphyry, passed through a very fine sieve7, and put back for use. It is given chiefly in cases of laxity and over-humidity of the liver, in enlargement of the spleen, after due evacuations; for which reason it restores young girls when pallid8, sickly, and lacking colour, to health and beauty; since it is very siccative, and is astringent9 without harm. But some who in every internal malady10 always talk of obstruction11 of the liver and spleen, think it beneficial in those cases because it removes obstructions12, mainly trusting to the opinions of certain Arabians94: wherefore they administer it to the dropsical and to those suffering from tumour13 of the liver or from chronic14 jaundice, and to persons troubled with hypochondrical melancholia or any stomachic disorder15, or add it to electuaries, without doubt to the grievous injury of many of their patients. Fallopius commends it prepared in his own way for tumours16 of the spleen, but is much mistaken; for loadstone is pre-eminently good for spleens relaxed with humour, and swollen17; but it is so far from curing spleens thickened into a tumour that it mightily18 confirms the malady. For those drugs which are strong siccatives and absorb humour force the viscera when hardened into a tumour more completely into a quasi-stony body. There are some who roast iron in a closed oven with fierce firing, and burn it strongly, until it turns red, and they call this Saffron of Mars; which is a powerful siccative, and more quickly penetrates20 the intestines21. Moreover they order violent exercise, that the drug may enter the viscera while heated and so reach the place affected22; wherefore also it is reduced to a very fine flour; otherwise it only sticks in the stomach and in the chyle and does not penetrate19 to the intestines. As a dry and earthy medicament, then, it is shown by the most certain experiments to be, after proper evacuations, a remedy for diseases arising from humour (when the viscera are charged and overflowing23 with watery24 rheum). Prepared steel is a medicament proper for enlarged spleen. Iron waters too are effectual in reducing the spleen, although as a rule iron is of a frigid25 and astringent efficiency, not a laxative; but it effects this neither by heat nor by cold, but from its own dryness when mixed with a penetrative fluid: it thus disperses26 the humour, thickens the villi, hardens the tissues, and contracts them when lax; while the inherent heat in the member thus strengthened, being increased in power, dissipates what is left. Whereas if the liver be hardened and weakened by old age or a chronic obstruction, or the spleen be shrivelled and contracted to a schirrus, by which troubles the fleshy parts of the limbs grow flaccid, and water under the skin invades the body, in the case of these conditions the introduction of iron accelerates the fatal end, and considerably27 increases the malady. Amongst recent writers there are some who in cases of drought of the liver prescribe, as a much lauded28 and famous remedy, the electuary of iron slag29, described by Rhazes95 in his ninth book ad Almansorem, Chap. 63, or prepared filings of steel; an evil and deadly advice: which if they do not some time understand from our philosophy, at least everyday experience, and the decline and death of their patients, will convince them, even the sluggish30 and lazy. Whether iron be warm or cold is variously contended by many. By Manardus, Curtius, Fallopius and others, many reasons are adduced on both sides; each settles it according to his own sentiment. Some make it to be cold, saying that iron has the property of refrigerating, because Aristotle in his Meteorologica would put iron in the class of things which grow concreted in cold by emission31 of the whole of their Heat: Galen, too, says that iron has its consistency32 from cold; also that it is an earthy and dense33 body. Further that iron is astringent, also that Chalybeate water quenches34 thirst: and they adduce the cooling effect of thermal35 iron waters. Others, however, maintain that it is Warm, because of Hippocrates making out that waters are warm which burst forth36 from places where iron exists. Galen says that in all metals there is considerable substance, or essence, of fire. Paolo96 affirms that iron waters are warm. Rhazes will have it that iron is warm and dry in the third degree. The Arabians think that it opens the spleen and liver; wherefore also that iron is warm. Montagnana recommends it in cold affections of the uterus and stomach. Thus do the smatterers cross swords together, and puzzle inquiring minds by their vague conjectures37, and wrangle38 for trifles as for goats' wool, when they philosophize, wrongly allowing and accepting properties: but these matters will appear more plainly by and by when we begin to discuss the causes of things; the clouds being dispersed39 that have so darkened all Philosophy. Filings, scales, and slag of iron are, as Avicenna makes out, not wanting in deleterious power (haply when they are not well prepared or are taken in larger quantity than is fit), hence they cause violent pain in the bowels40, roughness of the mouth and tongue, marasmus, and shrivelling of the limbs. But Avicenna wrongly97 and old-womanishly makes out that the proper antidote41 to this iron poison is loadstone to the weight of a drachm taken as a draught42 in the juice of mercurialis or of Beet43; for loadstone is of a twofold nature, usually malefiant and pernicious, nor does it resist iron, since it attracts it; nor when drunk in a draught in the form of powder does it avail to attract or repel44, but rather inflicts45 the same evils.
