Preservative Fumigations are largely talked of by all on those Occasions, and they with good Reason deserve to be practised. And of the great Number of Aromatick Roots and Woods, I should chiefly prefer Storax, Benjamin, Frankinsense, Myrrh, and Amber, the Wood of Juniper, Cypress and Cedar, the Leaves of Bays and Rosemary, and the Smell of Tarr and Pitch is no ways inferior to any of the rest, where its Scent is not particularly offensive, observing the burning of any or more of those Ingredients at such proper Distances of Time from each other, that the Air may always be sensibly impregnated therewith.
Amongst the Simples of the Vegitable Kind, Virginian Snake-Root cannot be too much admired, and is deservedly accounted the most Diaphoretick and Alexipharmick for expelling the pestilential Poison; its Dose, finely powder’d, is from four or six Grains to two Scruples, in a proper Vehicle; due Regard being had to the Strength and Age of the Patient.
The next is generally given to the Contrayerva Root, (from which also a Compound Medicine is admirably contrived, and made famous by its Success in the last Plague;) the Dose of this in fine Powder is from one Scruple to a Dram, in Angelica or Scordium Water, or in Wine, &c.
There are other Roots likewise of which many valuable Compounds are form’d in order to effect that with an united Force which they could not do singly; in this Class are the Roots of Angelica, Scorzonera, Butterbur, Masterwort, Tormentil, Zedoary, Garlick, Elicampane, Valerian, Birthwort, Gentian, Bitany, and many others, which may be found in other Writings.
Ginger, whether in the Root, powder’d, and candy’d deserve our Regard; for it is very powerful both to raise a breathing Sweat and defend the Spirits against the pestilential Impression.
From these Roots may be made Extracts, either with Spirit of Wine or Vinegar, for it is agreed by all, that the most subtil Particles collected together, and divested of their grosser and unprofitable Parts, become more efficacious in Medicinal Cases.
The Leaves of Vegetables most us’d in Practice are Scordiam, Rue, Sage, Veronica, the lesser Cataury, Scabious, Pimpinel, Marygolds, and Baum, from which, on Occasion, several Formulæ are contrived.
Good Vehicles to wash down and to facilitate the taking of many other Medicines, should be made of the Waters distilled from those Herbs while they are fresh and fragrant (having not yet lost their volatile Salt) for those which are commonly kept in the Shop, are insipid and of little Use.
