CHAP. X. Of the Passions of the Heart, and their Remedies.
AFter Cordial Medicines, vulgarly, though improperly, so call'd, it now follows for us to treat of the Passion of the Heart, in which the Heart is really ill affected, and therefore requires true Cordial Medicines: Under that name two affects, somewhat dif∣fering betwixt themselves are commonly denoted, to wit, The trembling of the Heart, and its panting: In both affects the motion or beat of the Heart seems to be disorderly, and in a manner Convulsive; but the irregularity of the first consists in the frequency of its Vibrations, and of the other in their vehe∣mency.
As to the Cure of the panting of the Heart, since its Causes are various and manifold, its Cure also must be various; for what some affirm, that those sorts of Remedies vulgarly call'd Cordials, which are reputed to revive the Heart, and to relieve it when ill affected, are proper in any of all these Cases, it is con∣trary both to reason and common experience.
We say then that the palpitation, or panting of the Heart, proceeds either from the fault of the Blood, or of the Arteries belonging to the Heart: If it happens through the fault of the Blood, the chief intent of Curing must be to raise the Blood to a better Crasis, it being then become too watery and unmeet for accension and fermenting, and to exalt or encrease its active principles which are then depress'd or diminish'd; for which end spirituous Medicines, also saline Medicines of all kinds, Sulphu∣reous and especially Chalybeates conduce: And to this place may be referr'd those things which are wont to be prescribed in the Pica or longing Disease, in the Leucophlegmatia, and in the cold Scurvy.
