CHAP. II. Instructions and Prescripts for other Distempers of the Liver.
THe Liver often uses to be faulty, especially in one of these two things, viz. either intercepting the Nutritive Juice ap∣pointed for other parts, it applies it to its proper use, as its gene∣rally seen in Children troubled with the Rickets, and in many o∣thers leading a sloathful and idle Life: Or Secondly, it too easily receives into its most inward Recesses, the filthiness of the de∣praved Blood, and all dreggy Excrements coming in its way, and retaining them does not only grow large, but is obstru∣cted in its Ductus's, whence oftentimes proceeds a Jaundise, or Dropsie, and tumours, and preternatural Concretions of divers kinds.
Therefore we must take care of these two things, viz. lest the Liver by taking to it self too much of the Nutritive Juice, grow to too great a Bulk, and lest by retaining the filthy dregs of the Blood, it be troubled with obstructions, and preternatural tu∣mours.
Both these faults are much more easily prevented than Cur'd: For the former is effected only by taking care that the Blood being well constituted in its Crasis, and enjoying a free Circulati∣on, both distributes the Nutritive Juice to the parts, and especi∣ally the outmost, and driving all its Excrements to all their re∣spective Emunctories deposes them there: And indeed the Hepa∣tick Medicines (vulgarly so call'd, though they regard the other Viscera as well as the Liver) do first and more immediately exert their vertue by purifying the Blood, rather than by correcting the Liver, or other entrals; for entring the Blood, and being im∣miscible with it, they so throughly exagitate it, that they make it discharge all its superfluities by their proper Emissaries; and if any Medicines are found by some specifick virtue, to have respect to one part more than to another, its because their Particles being more ally'd, and consequently associated to the Recrements to be separa∣ted
