Wherefore let none be deceived by the flattering Nature of this Distemper in the beginning, nor give themselves over for lost in the highest State, because these reviving Cordials are calculated for the weakest Constitutions, seeing at the same time they offend the Diseased Matter on the one Hand, they support Nature from sinking under any Evacuations on the other. It is therefore my Advice to the _Consumptive_, or _Consumptively-inclined_, and their Interest (by way of Prevention) to acquaint themselves in time with these Sovereign Antidotes. Better Counsel I cannot give to the best of my Friends, if they are desirous to save themselves a great deal of Pain and Misery, as well as Charges, and render their Lives comfortable to themselves and serviceable to others. The Warmness of these Medicines, which is the only Objection that ever I met with in the use of them, is so far from being a real Discouragement, as that upon serious and judicious Considerations, it becomes a Notable Argument to enforce the taking of them; for otherwise they would be too weak to engage the Original Cause of hectic, burning and putrid Fevers; whereas by this active Principle of Heat, they work so effectually upon the whole Mass of Chyle, as to separate the sharp and dispirited from the nutritious Particles thereof, thoroughly insinuate themselves into all the Avenues of the Adversary, cut and divide the tough viscous Humours which distemper the Veins, Arteries and Nerves, destroy the Acidity of the Nervous Juice, recover the Natural Temper of the Animal Spirits, sweeten the Mass of Blood, by separating the Impurities thereof by the Cutaneous Glands, gently forcing a Transpiration of the Feverish Particles of the whole, and so banish that Preternatural Heat which is Proof to all common Remedies. And that Diseases which carry in their outward Appearance a shew of preternatural Heat are thus to be treated with warm Medicines, is indeed observable to every discerning Eye: For the most malignant Fevers are attacked and conquered by the briskest and warmest _Alexipharmics_ and the most violent _Erysipelas_, or St _Anthony_’s _Fire_, is discussed and breathed out by strong and spirituous Fomentations, but are both of them exasperated by refrigerating or cooling Medicines, and their preternatural Heat more and more increased, till the one at length terminates in the _cold sweats of Death_, and the other in a compleat _Mortification_. To multiply Encomiums of this kind is remote from my intended Brevity, therefore take this remarkable one for all: The Efficacy of _Specific Medicines_ may be experienced from Mr _Boyle_’s unparalelled Treatise, herein referred to, and from the full Descriptions I have given any Chymist of Eminence, upon consulting each respective Patient’s Case, can effectually prepare them. But I would more particularly recommend for this Purpose the Skilful Mr _Boyle Godfrey_, in _Covent-Garden_. THO. NEVETT. [Illustration]
