CHAP. CVIII. Powders to dry up a Wound.
TAke Honey and unslak'd Lime, reduc'd to Powder, and searc'd, of each a Pound; mix 'em and put 'em into a Pot over a moderate Fire, stirring perpetually till they be throughly dry'd, and as it were Calcin'd, so that the Matter may be beaten and reduc'd to a fine Powder, which will incarnate and dry up a clean and red Wound. The only inconveniency of this Powder is, that it draws Flies to the Part in the Summer; nor will you find a more effectual Remedy among all that vast variety of Powders, with which Books of this Nature are stuff'd, if it be apply'd in a Season when there are no Flies. Charcoal beaten, old Shooes burn'd, sifted Ashes, Powder of Rosemary, or Sage, &c. are also very proper.
Other Powders to dry up Wounds.
Those who live in a place where Aqua-Fortis is made, may easily prepare a Pow∣der to dry up Wounds, and prevent the growth of Proud-Flesh; for the Caput Mortuum that remains in the Retort after the distillation of Aqua-Fortis, beaten to Powder and apply'd to the Wounds, is more effectual than Burnt Allum, Calcin'd Vitriol, and other such like Powders. The Distillers of Aqua-Fortis sell the Caput Mortuum at a very low rate, for if they do not meet with a Customer, they throw it away as useless; so that you may have a Porter's Burthen of it for Ten Pence. The distillation extracts only the most Spirituous and Volatil Parts of the Ingredients; but the Fixt Salts re∣main in the Caput Mortuum, and perform the effect requir'd in this case. Aqua Fortis is distill'd from Vitriol, or Bock-Allum, and Salt-Peter; and that which remains in the Retort, after the first Method of Distillation, is indu'd with the Virtues of Calcin'd Vi∣triol, as that which remains after the second, produces the effect of Burnt-Allum. I am not ignorant that there are several other ways of distilling Aqua-Fortis, but these are most usual; and besides, the Caput Mortuum is always proper in these cases, whatever be the Ingredients or Method of the Distillation; for example, Sal Armo∣niac, Sal Gemmae, and Bole-Armenic are join'd to Salt-Peter, in the distillation of those Waters that are known by the Name of Aqua-Regia, and leave in the Retort a Sedi∣ment or Caput Mortuum, which is very effectual for the drying of Wounds, and hin∣dering the growth of Proud-Flesh, if they be reduc'd to Powder, and apply'd to the Part. This Advice is particularly directed to Farriers, who use a great quantity of these sorts of Powders.
Before all other drying Powders, I prefer those that are made of the Caput Mor∣tuum, remaining in the Retort after the distillation of Spirit of Vitriol, because there is always some Bole-Armenic, mixt with the Vitriol to prevent its melting in the Retort, since it would not yield any Spirit, if it were in a state of Fusion. And the Bole mixt with the Calcin'd Vitriol, which is endu'd with a certain Balsamic Qua∣lity, makes a Composition that hinders the falling down of any Defluxion upon the Part, and dries the Wound very effectually and speedily.
Borax in fine Powder is an excellent Remedy to dry up Wounds and hinder the growth of Proud-Flesh.
Arsmart or Water-Pepper, dry'd and beaten to Powder dries up Wounds; and even if it be stamp'd while 'tis green, and put between the Wound and the Saddle, it cures a small Hurt.
Another Powder to dry up Wounds.
The drying up of Wounds is so much the more necessary, because the best Ointments keep the Parts moist, and are apt to breed Matter. Supposing, for ex∣ample, that you have dress'd a Quitter-bone, so long till there remains no bottom in the Sore, that is, till you can discover no cavity with your Probe, the Matter at the same time ceasing to run, you may conclude that 'tis time to apply Powders, espe∣cially if you ride your Horse.
