Take therefore in Gods name whatsoever Vegetable you list, and fill a great Glass Retort therewithall, and by degrees distill over all that will come. Separate the Oil from the Spirit, and the Spirit by rectification from the Volatile Salt; rectifie also this Volatile Salt, and the Spirit upon its own Caput Mort. or upon some other Salt of Ashes being first fired and calcined, and so they will become pure and lose that fetid stinch that they got in the Distillation: If one rectification is not enough, add a second or a third, always provided that it be done on the fixed Salt of that Herb out of which you drew the Spirit. Now though the Oil be also depurated by a rectification upon the Caput Mort. yet that depuration and rectification is not comparable to this of mine which I mention here, and therefore well do we prefer this way, and ’tis thus.
Take your black distilled Oil, put it in a Glass Retort with six or seven times as much rectified Spirit of Salt, and give first a gentle Fire, then a greater as the thing requires, so the Oil will pass over pure with the Spirit of Salt, and the stinch together with the blackness, will stay behind with a part of the Spirit of Salt. If now you will have that Oil yet purer, then rectifie it again with new Spirit of Salt untill both the Odour and Colour thereof please you. As for the Oil that stayed behind and did not ascend, separate it from the Spirit of Salt, and ’twill be somewhat thickish like to a black Balsam, and hath great virtue both inwardly and outwardly, but its inward use we need not, for we have enough of the pure Oil for that purpose. But that I may be yet farther serviceable to my Neighbour, and that he may understand me more thereby, I will make use of this similitude or example. Put case, that I have some four, five, or six pounds of the Seed of the Ash, which falls from the Trees in the Month of September or October, I do fill a Retort with the Same and by it distill the said Seeds, and I usually have about one or two, sometimes three, four, five, or six drams of black Oil, some ounces of Volatile Salt, and some pounds of Acid Spirit: Now forasmuch as I seek for the Oil onely, I separate this from the Spirit, and rectifie it with Spirit of Salt untill it becomes pure, and this I keep for my use; and I make of the Spirit either a certain Essence, as I have taught in the first part of my Pharmacopœa, or sugered Tablets, (or Lozenges) or what I please: And by this way do I get more Oil out of five or six pound of the Seed of the Trees, than otherwise by the Vesica or common hot Still, out of 100 pound, and that which remaineth after rectifying is profitable for external uses, if it be prepared as follows, viz. Separate this thick Oil from the Spirit of Salt and mix it with Wax, that so it may be made somewhat thicker, so as to be spread like an Emplaister, the which put upon the Reins, and use the distilled Oil inwardly, and thus this Emplaister will perform as much outwardly as the distilled Oil operates inwardly, and so the Patient is thereby doubly repaired and helped. And if you desire yet a third way of healing, then rectifie the acid Spirit well, and dissolve the Volatile Salt by subliming it with the Spirit, and use this Spirit every day (besides the inward use of the distilled Oil) on this wise: Heat it a little, and dip in it some Linnen Cloaths and therewith wash or bath the Back and Reins putting on the Emplaister afterwards, and hereby the Sick Person will in a short time (unless God doth in a singular manner put a stop thereto) certainly recover.
Note well, after this manner may you distill all other Vegetables into Oils, Spirits, and Emplaisters, and make use of them in this Disease, such as are Saxifrage, Parsly, Cumin, Carraways, and such like other Herbs and Roots: Neither is it always necessary to have the Ash Seed, unless you please: For that this Tree is not to be had in all places, and it yields also at some Seasons but little Seed? N. B. Here some may demand and say, you have taught us the manner of preparing Oils, Spirits, and Balsams out of the Seeds, but now if such a Medicine could be made out of the Herbs it would be something, for whence shall so much Seed be had? I Answer. If thou hast not so much Seed, thou may’st make the Medicine out of the whole Plant, as the Root, Stalk, Flowers, and Leaves: And the reason why I mentioned onely Seed, was this, because the chief virtue of all the Vegetables, is occultly placed and concentrated in the Seed, else the whole Plant may (as aforesaid) be made use of, which although it yield not so much Oil as the Seed does, yet may we even this way receive a good quantity: And if we should neither take Seed, Herb, Leaves, or Stalks, yet would the Root alone afford much Oil; but in Trees, as in Ash, Linden, Nut, Cherry, Peach, and the like, the very bare Wood it self will abundantly supply, if distilled per descensum, or by a Fire of suppression (of which afore,) so that a little Ash if rightly handled may afford you some pounds.
Nor are you to suppose that this way of plentifully preparing the Oils of Vegetables and clarifying them by Spirit of Salt, serves onely for such Vegetables as are good against the Stone, because I have onely instanced them as examples; No, but even all Vegetables, serving for every Disease, may be by this aforeshown way reduced into most sweet Medicaments. Nay not onely Vegetables may, but also Animals and Minerals too, but with some difference and distinction, which we shall mention in what follows.
There remains yet one thing more to be mentioned about the Oils of Vegetables, and the Distillation of them, and ’tis this. Some or other may reply and say, that haply such Oils as are prepared first by a Retort and per descensum, and then rectified and clarified by Spirit of Salt, are not equivalent in their virtues to those which are distilled in a Copper by the help of Water. For prevention of this Quæry, and the removal of such needless cares, we do in the first place demand, in what the virtues of the Animals and Vegetables do consist, whether or no in their connate and occult property, or in the Odour, Savour, and Tast. For answer, the greatest virtue of most Herbs, and living Creatures doth for the most and greatest part consist in their Co-nate or Co-born nature and property, and not in the Odour or Savour, as is sufficiently evident in some Plants, which have scarce any Odour or Savour, and yet are found notably efficacious in Medicine, and some there are both of a Sweet Odour and Savour, which have no Medicinal use, and some that have an ungratefull Odour and Savour, and yet have no mean Medicinal Virtues. And many there be of things which both smell and tast sweet, and are also profitable in medicine, because God hath created them so or to that intent. I must needs confess that sometimes an Odour or Savour of such an Herb as hath but little virtue is notably refreshing and comfortable to the Vital Spirit, nay more, the very seeing of a fair and comely thing is capable of comforting the Heart, and an ugly thing of debilitating it; a notable example hereof we have in a friendly man, and in Gold, as being things which by the very beholding of them do refresh the Heart, whereas contrariwise, an angry man, and a venemous Creature do terrifie it, (viz. the Heart) and as ’twere make it Sick, yea and sometimes kill outright. Besides, not onely the seeing of such and such objects do profit or hurt, but even the very voice of a man, or of a living Creature do hurt, weaken, and kill, if proceeding from a malignity. Farther, the bare imagination can effect good or evil, heal or hurt; but this belongs not to this place, but such things are treated of in my short Treatise of things natural and supernatural. That which I have here spoken is to this end, that the unskilfull might know, that the virtues of Vegetables do consist more in their Co-born Nature than in the Savour or Odour, and that this Distillation by a Retort, and rectification by Spirit of Salt, can neither add to or diminish from their virtues, because their virtue remains always unhurt, in what manner soever the Distillation be made, provided that that which is distilled be diligently depurated, and all the ungratefulness removed therefrom which it got in the operation, that is to say, when Oils are adust (or Savour of burning) by their being distilled in a Retort, then that accident may be taken away from them by rectification with Spirit of Salt, and this now I add for the sake of the Ignorant.
Moreover as it is with Vegetables, so likewise must you order your distillation of the Oil, Salt, and Spirit of Animals: Neither need you to proceed farther or otherwise. As for the Vertues of both Animals and Vegetables, the Physician ought to know them by their Signature, and not by the books of Writers, because the Signature doth shew us the Vertues of all things much clearer and righter than many Writers, who write many things meerly from hear say, whenas themselves do in truth know very little or nothing at all. And thus for this time I omit to say any more, for that the present occasion will not admit of a more prolix discourse hereabouts. What I have done is for the Sick that are poor, that they might know my method of purifying the Spirits of the Acid Salts from Vegetables or Animals, by Spirit of Salt, and of bringing them into wholsome Medicaments: And this cannot be accomplished so plentifully without this Medium; and now this way being shown, the Poor may also enjoy the benefit of them, and be able to pay the Apothecary, whenas before even the Rich could hardly have any of the good (in them). Note well, you are yet farther to observe, that indeed the Animals are first to be distilled by a Retort (as we spake before concerning the Vegetables) that so their Oil, Spirit, and Volatile Salt, may pass over together; and their Spirit and Volatile Salt may be rectified and purified the aforesaid way. But the Oil will not come over by a bare Spirit of Common Salt, or of Niter, but that Spirit must be first concentrated with Calaminaris, and then it brings over the Oils of Animals, else not. But as touching the Concentration of the Acid Spirit for this rectification, we shall speak of it anon, and will therefore first set down (for better instructions sake) one certain process of distillation and rectification, lest any might err, and that all might rightly apprehend my meaning; and ’tis this: Take some pounds of Turpentine, distill thence an Oil, and the Fæces of the Turpentine will stay behind. This Oil though it be rendred by Distillation purer than ’twas before, yet it hath put on another nature by means of the Fire, viz. an hotter nature, and therefore serveth not for every effect which the Turpentine before served for, because the Turpentine is not very thick nor very thin, nor too hot or too cold, nor too subtile or too thick or gross, but is of a temperate essence and property, which now by Distillation it possesseth no longer, but, because of its heat and subtilty, it is unusefull. Well, what of all this? Why some or other might have objected to me that indeed things are by distillation rendred more pure and subtile, but doe thereby get an hotter nature and vertue, and therefore that way of purifying doth not doe well in all subjects. Well, to prevent this objection, and that the distilled Oils may after their purification be restored to the same degree of thickness, rarity or thinness, colour or frigidity, that they had before, and yet retain the purity they got by distilling: the method is easie, and is thus done. Suppose that Turpentine be (as it is Turpentine) hot and subtile in the first degree, but being distilled it arrives to the third degree, and being rectified to the fourth. I must now needs confess that that subtile Oil is to be used onely in cold affects, and in no others, whereas it might before have been employed about other accidents. To this I say, and yield, that if it be proceeded with after the common and known way, ’tis so: But my way is far otherwise to be reckoned of: For though hereby the things distilled doe, together with a purity, get a subtile heat, and doe in some operations become too thin and hot, yet in rectifying by the Acid Spirit, such qualities are broken, divided and dissipated, so that it is in part rendered of a like thickness and tenacity as it was at first, and a part of it remains subtile. So that you may have out of one subject, both thin, hot, thick and temperate parts together, but both of those parts pure, as shall be evinced by this Example.
The Spirit of Salt, or of Niter is indeed inwardly a mere Fire, but externally a mere Cold, by which all thin things do stiffen and wax hard. Therefore as the distillation doth induce heat, expels and extenuates, so the rectification doth by the acid Spirit compel or drive the same inward, thickneth it, and reduceth it into an equal temperature: For the Oil in the first distillation is plainly hotter and subtiller both within and without, than ’twas before, but by rectifying it with the acid Spirit, the most subtil part comes over first, then the middle part, and the thickest resides in the bottom, which is of an equal degree of heat and thickness as the Turpentine is, and is as usefull both inwardly and outwardly as the Turpentine it self is. And I have over and above that middle Oil, and that most subtil Spirit burning and penetrative, the which I can make use of for those effects, which require such subtilty, or if I lift, thicken it with what I left remaining of it self behind, which is thick, but yet purified, or else thicken it with some other convenient thing. And thus may I reduce one Subject into as many Degrees as I please, whereas the Turpentine had before but onely one Degree: From hence may the friendly Reader see what Basis this my distillation and rectification by an acid Spirit hath: Whereby not onely a great deal, yea 3, 4, or 5 times more Oil comes over than by the common hot Still; but also the Volatile Salts and the Spirits, and sharp Vinegars may be hereby gotten out of Vegetables and Animals, and besides a pretty quantity of thick Oil to be externally used, and which otherwise in distillation by water in a Vesica or hot Still, would remain wholly behind. The benefit therefore of this distillation and rectification, doth not onely consist in the getting a far greater quantity of the pure Oil, but also in getting the Volatile Salt, (which as to its use is equivalent in vertue to the Oil) and withal, an acid Spirit which abundantly sufficeth both inwardly and outwardly according to its Office. I do therefore earnestly demand of all skilfull Spagyrists (for ’tis in vain to appeal to such as are yet ignorant what the Art of Fire is) whether or no this distillation is not to be preferred before the others, and to be made use of for the benefit of mankind. I hope that the well minded Reader will follow this rule, and will apprehend from this one process onely, so much as to be afterwards easily able to reduce every distilled Oil into its former hardness, by the help of an acid Spirit. Let us consider Amber onely, ’tis indeed a fine transparent kind of stone, which was before (or at first) soft and fluid as Turpentine was, an Oil or a kind of thin Bitumen, but now so hardened by the salt Water that it may be beaten to a Powder, yet may it be distilled and so separated and cleansed from its earthly Nature: And the pure Oil may be reduced into its former hardness, by the help of Spirit of Salt onely: For it became at first hardened by Salt, when it flowed thin out of the Rock: But of this enough, we shall say more of it in another place.
Now follows the Process of purifying Minerals by distillation or sublimation, and of depurating them even to the utmost, by rectifying them by an Acid Spirit. To exemplifie which, I will instance in Common Sulphur, according to which rule the other purification of Minerals may be instituted.
Take common Brimstone, sublime it the usual way into Flowers, or by it self in a Coated glass retort, or let it be mixt with decrepitated Salt, for so will it be freed from its most crude terrestreity, and be rendered fit for a farther Mundification by an Acid Spirit. Take one pound of these Flowers of Sulphur, and put it into a strong Glass Body coated, then pour in one or two pounds of the Spirit of Niter, or of common Salt, and place it in an Earthen-vessel in Sand: Put there under a Fire, encreasing it gradually untill the Spirit of Salt boils in the Retort, and the Sulphur melts, and there will swim somewhat like Oil on the top of the Water: N. B. An Alembick is to be put on the Body, lest the Spirit of Salt ascending up, goes away in fume; but in the Alembick it will be refrigerated, condensed, and may be saved. This boiling is finished in some five or six hours, and so the Sulphur is mundified, and becomes as clear and transparent as Glass. For the Spirit of Salt attracteth the Metalline Parts, which are in the Sulphur, whether it be Copper, Arsenick, Auripigment, Vitriol, or such-like impurities which are commonly adherent, and stickers on to the Sulphur, and would otherwise have remained in it, and done more hurt in Medicine: And this Paracelsus knew, and adviseth to beware of; For certain it is there lye hidden in Sulphur incredible Vertues, and such as its common Flowers do not shew or discover, as being yet infected with Mineral venenate Spirits, which may be taken thencefrom by the Spirit of Salt. And if then either the Flowers be sublimed out of it, or that it be dissolved in a Balneum with Spirit of Juniper, or of Turpentine, or be by any other way reduced into a Liquid form, it doth much good in Medicine, nor is there any more fear of its venomous nature, for the Spirit of Salt hath took that away. I could indeed here mention some preparations of Common Sulphur, into efficacious Medicaments, but that I have intended to proceed no farther with it here, than onely as touching its purification by the Spirit of Salt: the rest we will leave to another time.
As Sulphur may be proceeded with, so likewise may you deal with the other Minerals, and first mundifie them by a Retort, and distill them into black Oils, then may the Oils be clarified with Spirit of Salt, and be reduced into sweet Oils and Balsams. Nor will any man easily believe what notable Vertues there are hidden in the mountainous and terrestrial Minerals, and yet not usefull at all inwardly, because of their Arsenical nature, which may with ease be taken away from them by Spirit of Salt, and be thereby more securely used as to Medicine. And had I not purposely tried it, I would not at all have written of it. For information therefore of the unexperienced, I will tell you a story, whereby it will appear, that those Minerals do usually lodge in them evil and venomous Arsenical Spirits.
