CHAP. XXI. To make Aqua reale, vel Imperiale, the which maketh the teeth white presently, incarnateth the Gums, and causeth a good breath.

THe teeth being black and rustie, and full of filth, and the Gums putrified or corrupt, are the worst things that may be seen in man or woman, and are also very unwholsome; and the Remedie to make the teeth white, and to help the gumms, is thus: Make this water, and use it in this order as I will shew thee.

Take Sal Gemmae, Roch Allum, Brimstone of each two pound, Borax ℥. x. Pearl beat fine, Corall, each ℥. ii. Pure di∣stilled Vinegar ℥. iiii. Put all the aforesaid matters in a Goord, with his head and receiver, and give it fire accord∣ing to Art, and at the last there will come forth a white wa∣ter like Milk, the which after it hath stood a while, will waxe clear. You shall understand, that this water is above all other waters in the world, to help Ulcers in the mouth, and to in∣carnate the gums, and to make the teeth white, and causeth a good breath in those which are troubled with the aforesaid matters. For of this water I have made great quantitie, and it hath been carried into Spain, into Almain, into Poland, into Constantinople, and in divers other Countries, as though it had been a Divine thing, and not material.

For truly this experience doth cause the world to wonder at it, the use hereof I have written in this Book, and here∣after I will write it again in some of my Books, where oc∣casion shall serve to use it in cures.
