THERE are other Roots likewise which daily Experience hath taught us to be very good for the same Purposes; and with which, as Occasion requires, many valuable Compounds are formed, in order to effect that with a 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_, _Bittany_, and many others, which any Person that loves Variety may find in proper Authors. BUT even Gratitude obliges me not to omit saying somewhat of _Ginger_, which I have prescribed both in the Root powdered, and candied, many Times with great Success, 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 more subtil Particles collected together, and divested of their grosser and unprofitable Parts, become more efficacious in Medicinal Cases. THE Leaves of Vegetables most used in Practice, are _Scordium_, _Rue_, _Sage_, _Veronica_, _Dragon_, the _lesser Centaury_, _Scabious_, _Pimpinel_, _Marygolds_ and _Baum_, and from which, on Occasion, are several _Formulæ_ contrived. GOOD Vehicles to wash down and facilitate the taking more efficacious Medicines, are 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 for Ornament in the Shops are insipid, and of little or no Worth. A _Clyssus_ also of the same Herbs is preferrable to the Waters, made after this Manner, let a Quantity of Water be drawn from the green and succulent Plant, and the Juice be expressed from another Parcel of the same Herb, and depurated by standing; let then both be evaporated to the Consistence of _Honey_, and from it a Tincture drawn with some more distilled Water and a little Spirit of Wine, which is again by Evaporation to be reduced into an Extract; also from the dryed Plant draw its essential Oil, and from the _Residium_ after Distillation the Salt. Of the Extract take ʒ iv. of the _Salt_ ℥ [ss.], and of the _Oil_ 50 drops, and mix them together, where let them lie to incorporate more intimately with one another. The inspissated Juices likewise of these Ingredients are of good Effect, and in the Winter, Decoctions may conveniently be made of them for the same medical Purposes; and further, that the Remedies in this Case may be yet the more efficacious, they may be joined with _Alkaline-Salts_ dissolved in a proper _Menstruum_: For by this Means the Tone of the Stomach will be strengthened, Putrefaction will be prevented, the nitro-saline _Effluvia_ will be resisted, or at least precipitated, and a _Diaphoresis_ promoted.
