That which seems at once to fulfil most of these intentions, is taking of Tobacco in a Pipe; the Smoke of this secures those parts which lye openest, and at once intercepts the Contagion from the Brain, Lungs, and Stomach: Nay more than this, it stirs the Blood and Spirits all the Body over, and makes them shake off any poysonous Matter that adher'd to them: Insomuch that =Diemerbroek= accounts it not only a Preservative, but tells us, that himself, when he was several times infected, by taking five or six Pipes of Tobacco together was presently cur'd. And amongst us in _England_ 'tis reported, That in the last great Plague, no Tobacco-Shop was infected: If 'tis not of so great virtue still amongst us, the reason is, because most Men have been accustomed to take it so excessively; wherefore it is grown so familiar to them, that it produceth no alteration when it should be us'd as an Antidote. Besides the frequent use of Tobacco, which doubtless in time of Plague may be profitable for them that can take it; others, and also Tobacconists, at sometimes should be furnished with something to smell to when they pass through infected Places. _Wormwood_ and _Rue_, _Galbanum_, _Castor_ and _Vinegar_ are good: The vulgar practice of putting _Mithridate_, or _Treacle_, or _Tar_ in their Nostrils, may be very useful; or to have a _Pomander_ to carry in ones hand, or put into the top of a Staff. _Take of the Roots of_ Contrayerva _and_ Virginian-Snakeweed _pouder'd, of each Two Drams; of the best_ Myrrh _pouder'd, half an Ounce; of_ Camphire _half a Dram. Let it be made a Pouder_. Part of this may be enclos'd in a fine Silk Bag, and oftentimes dip it in _Pestilential Vinegar_, and so smell to it. To the other part of this, add _Oyl of Nutmegs_ by Expression, and Oyl of _Cap-ivy_, of each a Dram, or as much as will make it into a Mass; also add of _Balsam of Peru_ one Scruple. Dip Cotton Wool in _Elixir Proprietatis_, inclose it in fine Silk, and put it in the head of a Staff, or Civet Box, to smell to. For Medicines to hold in the Mouth, and chew on, Roots of _Zedoary_, _Contrayerva_, and _Snakeweed_ are very good; also Roots of _Enulacampane_, _Angelica_, and _Masterwort_; these either alone, or macerated in _Vinegar_, and dried again. _Myrrh_ is very excellent: Some commend Tobacco, and chew it almost continually. These are the chiefest Remedies which help to keep Infection out of the Body. There is yet another sort which serves to let it out, and carry it away, before it grows to a head, _viz. Issues_, which have been found by often experience to be good Preservatives in time of Plague: For as much as Nature having a constant vent for excrementitious matter thrown off the Blood, by the same way expels poysonous Atoms soon after they are receiv'd into the Body.
