I have taught in the second part of my spagyrical Pharmacopæa, a way of correcting venemous insects by the fixt Liquor of Niter, and of transmuting their venome into an effectual Medicine, which [way of preparation] he who is studious of good medicaments will there find. But now in this place is taught, by what means such like Vermine, and such Herbs as abound with Venome are to be corrected by the con-centrated fire of salt, and to be turned into excellent and penetrative medicaments. The operation whereof is thus.
Pour into some glass vessel, one, two or three ounces of our con-centrated fire of salt, then put thereunto such Vermine as you would prepare your Medicine of, one after another, provided that you do not put more in, than the said fire is able to dissolve and consume. When all are dissolved and converted into water, all the poysonousness is lost [or gone] and they become good medicaments.
LXIX. The manner of separating the medicament made of Vermine dissolved by the moist fires.
There is found to be a great difference amongst Vermine and venemous insects. For some of them are of a dry nature and property, some of a moist, some of a fat and oily nature, insomuch that it is altogether needfull to make a due distinction of their natures. Such insects as be of a dry nature as Cantharides and such like, are to be used in the form of a salt. The aqueous Vermine, as Earth-worms, Spiders, and such like; they exhibit their medicinality in the form of a Liquor: The Balsamick Vermine, as the May-worms, and others of that kind, do (beside the medicament they afford) yield also a fat and Balsamick Oyl; and indeed (both for external and internal medicinal use,) much more effectual than the Liquor it self.
But that the thing may be the better understood, I will here set down an operation, which every one may follow as a leading Star.
LXX. How the operation in dealing with all kinds of Vermine is to be used.
Take some ounces of May-worms, put them in a glass, pour upon them so much of the concentrated spirit of salt, that the Worms may be well covered therewith and be by little and little dissolved; after that they are wholly dissolved, put the solution into a separating glass, shut the mouth of the glass with your finger, then turn the glass upside down, keeping it so long shut with your finger, till all the fat oil swim at top of the Liquour. Then take away your finger that the Liquour may run out, and when the oil comes, shut the mouth of the glass again with your finger, and let it run out into another glass. Keep this Oil or Balsam as a precious treasure, with the which thou wilt perform wonderfull effects in the curing of diseases, but principally in the Gout and Stone. But yet thou wilt get but little oil from these Worms, and when you put them into your dissolving Liquor, you must have a care that you do not touch them with your hands, but take or catch them with a small Forceps, and so put them into your glass. For they have in them this property; if you touch them with your hands, they presently colour them with their fat Balsom that they cast out, which somewhat resembles the smell of Musk. As if they should say, Pray let us live, for we give thee all we have: Take this Balsom and make use thereof for the curing of incurable diseases.
Some men studiously carefull in such affairs have gathered this Balsom, and have found it to be far more efficacious than the Worms themselves, yea indeed too strong, because they were ignorant of the way of correcting it.
LXXI. The separation of the medicinal Liquor from the moist fire, after the separation of the Oil.
As concerning the Liquor from which the Balsom is separated, viz. the medicinal parts is very hardly separated without a mortifying of the moist fire; therefore the moist fire of the Salt is to be killed with a contrary fire, that so the separation that is required may be made; and ’tis thus to be effected.
