There are many sorts of _Druggs_, whereof some are beneficial, by assisting those particular Parts of the Body that are oppressed and offended, either by Superfluous Humours, or Malignant Humours: but, there are some sorts of Druggs that are as malicious to the Human Life, as the Assistant Druggs are friendly. Several sorts of Druggs, have several sorts of Actions, which causes several Effects; as, some Druggs work by Siege; others, by Urine; some, by Vomit; others, by Spitting; others, by Sweating; some cause sleep; some are hot, others are cold; some dry, others moist. But this is to be noted, That 'tis not the Motions of the Druggs, but the Motion of the Humours, which the Druggs occasion to flow; and not only to flow, but to flow after such or such a manner and way. The Actions of Druggs, are like the Actions of Hounds, or Hawks, that flye at a particular Bird, or run after a particular beast of their own kind, although of a different sort: The only difference is, That Druggs are not only of a different sort, but of a different Kind from Animal Kind; at least, from Human Sort. CHAP. XXII. Of the Various Humours of Druggs. The reason, one and the same Quantity or Dose of one and the same sort of Purging-Druggs or Medicine, will often work differently in several Human Bodies; as also, differently in one and the same Body, at several times of taking the same sorts of Medicines; is, That several Parts of one and the same sort, may be differently humoured: as, some to be duller and slower than others; and some to be more active than others. Also, some Parts may be ill-natured, and cause Factions amongst the Parts of the Body; whereas others will endeavour to rectifie Disorders, or Factions. And sometimes both the Druggs, and the Body, falls out; and then there is a dangerous strife; the Body striving to expel the Physick, and the Physick endeavouring to stay in the Body, to do the Body some mischief. Also, some Parts of one and the same sort, may be so Irregular, as to hunt not only the superfluous Humours, or the Malignant Humors, but all sorts of flowing Parts; which may cause so great and general Disorder, as may endanger Human Life.
