If you intend to make a good medicine out of iron or steel or copper joyned with tartar, then for the iron or steel take an iron pot, and for copper a kettel of copper, make them very clean and put in it the filings of iron, or steel, or copper, which you please, and twice as much of pure tartar made into powder, and so much water, that the tartar maybe dissolved well by it in the boyling, and so boyl the metal with the tartar-water so long, till it be deeply coloured by the metal, as red by the iron, and deep green by the copper; and when the water in the boyling doth waste, you must still supply it with other, that the tartar may not burn; for there must be alwayes so much water, that no skin of the tartar may rise at the top, but that it remain always open, and there must not be too much water neither, lest it be too sweet, and not able to dissolve the metal. The solution of iron or steel being come to be red and sweet, and in taste like unto vitriol, but green and bitter of copper, pour it off warm by inclination into an other clean vessel, and let it stand so long again in a very gentle heat of coals, till almost all the water be evaporated, and the dissolved metal with the tartar remain in the consistency of honey.
Which metallical liquor may be used inwardly and outwardly (especially that of iron) which doth purge gently, and openeth the obstructions of the Liver and Spleen: cleanseth the Stomach, and killeth Worms: externally used it is a good wound balsome, and goes far beyond all such as are made of vegetables. It is a singular treasure, not only for to cure new wounds; but also for to cleanse and heal old corrupt exulcerated sores, turned to fistulaes; but the liquor of copper is not so safe for to be used inwardly, for it is not only very unpleasant in taste, but also causeth vehement vomits: and therefore I would not advise any one to be forward to use it, unless it be for strong folks and for to kill worms in them, for which purpose it is excellent good and surpasseth all other medicines whatsoever; but to little children it ought not to be given at all, in regard that it is of far too strong an operation for them.
N. B. And if you will use it to strong bodies against the worms or stomach-agues, you must observe that the patient (in case that he cannot get it up) thrust his finger into the throat to further the vomiting, that it may not stay behind, but come forth again out of the body, which done health followeth upon it; but if it remain in the body, it causeth a loathsomeness to use it any more. And therefore you must take heed to use it warily: and in regard that this liquor is very bitter, you may mix it with some sugar, to facilitate the taking thereof; but that of iron needeth no such correction, it being sweet enough of it self, and therefore I commend and prefer it before the other: but if you will needs have that of copper (because it worketh so strongly) then the Patient must keep in from the cold aire, and not presently after the operation load the stomach with strong drink and superfluity of meat, contenting himself with some warm broth and a little cup of wine or beer, and the next day his meat and drink will taste the better with him, and do him so much the more good.
But externally, this liquor is of the same use with that of iron or steel, yea, proveth more effectual and speedier in healing. It would be good that Surgeons knew how to prepare it, and would use it instead of their salves, wherewith many fresh wounds are spoyled and turned into horrid ulcers, especially it requiring so little cost and pains to make it. And if you would have these liquors purer yet, you must pour on spirit of wine, and extract them, and they will easily yield their tincture, and leave many fæces behind which are good for nothing: but the tincture will be so much the better, purer, and more effectual, so that you need use but four or five drops for purging, whereas of the gross liquor you must have from 4, 6, 8. to 12. or 16. drops: and this extracted tincture worketh also much better externally, and keepeth longer than the balsome or liquor, which in time is corrupted, but the extraction is never spoiled. But if you will distil the liquor or balsome, it is needless that it be extracted first, but may be distilled so as the boyling made it, after the same manner, as above was taught for Lead, and there will come over a yellow spirit and oyl from iron or steel, and from copper a greenish spirit and oyl.
The spirit and oyl of iron may safely be used in the plague, feavers, obstructions, and corruption of blood, from ʒ i. to ℥ i. It is much better to provoke sweat, than that which is made of crude Tartar, without addition of a metal: the like doth that also which is made of copper and more effectually yet, and sometimes causeth a vomit, if it be used in a greater quantity, than is fitting.
N. B. Although the Chymists do prefer copper before iron, as a more firm and ripe metal, nevertheless it is found by experience, that iron or steel by reason of its sweetness is better to be used for an inward medicine than copper. But for external use, copper (if it be well prepared) hath the preheminence, being an appropriate medicine for all ulcers and open sores, in all the parts of the body, if the same inwardly be kept clean by fitting purges. For not only the now described medicine, but also many more besides, are taught to be made out of copper in other places of my books.
A Country-physick and purge I will teach for those, which either live far from Apothecary-shops, or have no money to spare for physick; and it is to be made out of iron and copper, whereby they may cleanse their slimy stomachs, spoyled by a disorderly dyet, whence head-aches, worms, agues, and other diseases are occasioned, warning withal those that are either too old or too young, or else decayed and weak, and so not strong enough for such powerful physick, that they will forbear to use it, lest besides the worms, they kill and expel life it self also; but those that are of a strong constitution, and a middle age, and of a sound heart, may safely use this purge, whereby stomach-agues, belly-worms, and may other occult diseases may be cured with good success. The preparation is done thus: Take ℥ ss. of pure tartar made into powder, & ℥ ss. or ℥ j. of sugar or honey, and ℥ v. or ℥ vj. of spring or rain water, put all into a clean copper vessel which is not greasy, and boyl it upon a coal fire as long or somewhat longer than you use to boyl an egg, or at the furthest half a quarter of an hour; take off the skum in boyling, let it stand till it be milk-warm, so that it may be drunk. This potion tasting almost like warm wine sweetned with sugar, give unto the patient to drink, and let him fast upon it, and within half an hour it will begin to work upwards and downwards; whereat you need not be amazed, but only keep the body warm, and within an hour it will have done working. But if you will drive out worms from little children by purging, then instead of the copper-vessel, take a clean iron-vessel, and put in a less quantity of tartar, sugar and water, and boyl it as abovesaid, and give it to them, and it will purge only downward, but sometimes it will also give a gentle vomit, which will do them no hurt, but rather will cleanse the stomach the better. But if the drink be too weak, so that it doth not work, it may be used again the next day (but you must take more of the ingredients, or else let them boyl longer) there is no danger in it at all, if you proceed aright, and it is much pleasanter to take, than the bitter worm-feed, wherewith they usually torment children.
The reason why this decoction works in this manner is, that the tartar and sugar being boyled in metallical vessels with water, work upon the metal, and extract vertue out of it, which causeth vomiting and purging (the Tartar also being helpful to it.)
How to make a Tartarised spirit of Mercury.
Vulgar Mercury cannot be dissolved like the former metals with tartar and water, without any foregoing preparation; but must be sublimed first with salt and vitriol, or crystallised with Aqua fortis, and then it may be dissolved by boyling with tartar and water, and reduced into a balsame, like other metals, but is not to be used inwardly, unless it be digested a sufficient time, so that its fierceness be allayed: Externally it may safely be used in all desperate, especially venereal sores, and it is a very effectual and profitable medicine for them. But most of all it doth serve for Alchymy, although few do know this guest, because he will not be seen by every one. The spirit which comes over from it by distillation, is an admirable thing not only in physick, but also in Alchymy: yet you must take heed, that instead of a friend, you do not harbor a great enemy: for its force and vertue is very great and powerful.
