Another Medicine which should be followed with Exercise, is the Chalybeate, especially in Dropical Subjects; not for fear it should lye heavy upon the Stomach, as the Vulgar think, but because in these People, the Contents of the Stomach are much rarefi’d and flatulent, and the Steel is apt to cause Distentions and Gripes, and other troublesome Symptomes; so that it is necessary, the whole Body should be well warm’d, that those Particles may be discuss’d, and the Stomach qualifi’d to bear the Chalybeate; besides, that acquired Heat will enable it, after it comes into the Blood, to display its Effects the sooner, either as a Corroborative, or a Diuretick. In Hysterick and Hypochondriacal Persons, this Medicine, gives trouble after another manner, by Costiveness, by Head-ach, and Heating the whole Body too much; now all these are much qualifi’d by Exercise, for it will procure a Ventilation of many of those Particles, which the Medicine agitates and throws upon the Membranes. I might proceed to enquire into the Nature of _Balsamicks_, but that I shall have occasion, as I proceed, rather to say something against their Use, in one of the Distempers, which I shall consider; but if they are to be us’d, what I have already said in Relation to the Fluids, will shew that a great deal depends upon a proper degree of Agitation in the Blood, for the uniting and throughly mixing the Particles, of a Medicine of this Nature, that it may be transmitted to the designed Part to some Purpose; and as it would be convenient a Balsamick should be taken in a larger quantity, if the Stomach of sick People could bear it; so during the Time of Exercise, while the Body is heated, the Stomach can bear a greater quantity than at other times, without any Sense of Irritation, or Inclination to throw it up. But I shall forbear to enlarge any more on these things, and go on to the Distempers, which seem most Naturally to demand this kind of Assistance; in Treating of which it will be easie to discern in every several Case, how the Gymnastick Part will agree, or fall in with the Pharmaceutick. OF THE _CONSUMPTION_. The First of the Distempers then, is the _Consumption of the Lungs_; I take this to fall under the Power of Exercise; for these two Reasons. _First_, Because the Morbifick Particles, which are the immediate Cause of the Disease, seem to be of a looser Texture, to be less intimately combin’d in the Blood, than in most Chronical Cases, the Particles which occasion each Distemperature seem to be. _Secondly_, Because this Case requires the carrying off the Acrimonious Particles, by equal Secretions, rather than by any one particular Emunctory of the Body.
