of evil Humors to them; which by an eroding quality consume the Gums, or the roots of the Teeth: also from the Scurvy, and Mercurial Unctions in the Venereal Disease.
III. The Prognosticks. If they are very loose, and have been long so, they will scarcely ever be made fast again.
IV. The Cure. If they are loosened by any external violence, their fastning is endeavoured by Astringents: as, ℞ Roots of Cinkfoil, Bistort, A. ℥ j. Cype∣rus ℥ ss. Sumach ʒ iij. boil in Smiths-forge-water, filter, and add Aluin ʒij. with which often wash the Mouth: and it may be so much the better, if a little red Wine be added to it.
V. If it is from a defect of nourishment, there is scarcely any Remedy to be applied; the greatest help that can be, is to apply astringent and strength∣ning things to the Gums.
VI. If it is from too great humidity, use things drying, and something astringing: but you ought to beware of such Astrin∣gents as may make the Teeth black, as Pomgranate-peels, Ba∣laustians, Galls, Vitriol, Chal∣citis, &c.
VII. These things are profitable; as roots of Male-fern, of Cink∣foil, of Bistort, of Dock, of Tormentil, of Capers; leaves of Myrtles, Lentisk, unripe Med∣lars; flowers of red Roses, cups of Acorns, Hazle-nuts: a Decoction of all or any of which may be made in red, or sharp, or sowr Wine, with which the Teeth and Gums may be often washed.
VIII. And to draw forth the Humidities, the roots of Pyre∣thrum, and Sage-leaves may be added.
IX. The Teeth also may be often rubbed with this styptick Pouder: ℞ Roch-alum, Mastich, Sanguis Draconis, Terra Sigil∣lata, fine Bole, A. ʒ ij. roots of Orrice and Bistort, Harts-horn burnt white, red Coral levigated, Ivory burnt white, A. ʒ j. Pipe∣ris, Pyrethri, A. ℈ ij. Mastich, Olibanum, A. ʒ ss. mix, and make a Pouder.
X. Often wash the Teeth and Gums with Tincture of Myrrh, made with common Brandy: or, for want of it, with good red Port-wine: this wonderfully strengthens them, and destroys Putrifaction.
XI. Or they may be washed with a Decoction, of Moufear, roots of Bistort and Tormentil, in Smiths-forge-water, boiled to a consumption of a third part, and then filtred.
XII. Or, ℞ Leaves of Myr∣tles, Berries of Services, A. ℥ iij. unripe Medlars ℥ ij. unripe wild Pears ℥ j. Sarcocol ℥ ss. Roch∣alum ʒiij. Vinegar of Squills ℥iij. red Wine a quart; mix, boil to the consumption of a third part, and then strain and filter; and add thereto Syrup of Myrtles, or Syrup of Limons.
XIII. This is much com∣mended: ℞ Acorns ℥ j. burnt Alum ʒj. Acacia ʒ ss. red Roses dried M ss. red Port-wine a quart: boil to the consumption of a third part, strain, and wash often therewith.
XIV. ℞ Pouder of Juniper∣gum
