He will discover the inefficacy of many of the Syrups and other Medicines in the Shops, made of such ingredients, the qualities whereof, what with boiling, what with the great quantity of Sugar necessary to keep them, are either made useless or opposite to the ends they are proposed for. Especially in such Plants, Seeds, and Flowers, which consist of fine volatil parts, and even in drying and pounding, or the least boiling exhale and evaporate, and therefore in the common way of ordering them, lose their whole vertue or most of their efficacy, and alter in their properties. From which by several methods known to some Physicians, very generous and singular Medicines may be produced. He need not use so large Compositions consisting of such confused and contrary ingredients, and will find good reason to lay aside those unintelligible and unreasonable Compositions of Mithridate, and Treacle, and the so much magnified Treacle-water, and will substitute better in their places, of smaller charge, and less trouble; and this all Physicians I have conversed with, and the College it self, by their Book published for the common good, in the year before the Plague, and all those Physicians in this City, who make or intend to make their own Medicines, do confess. But here Apothecaries open wide, and cry out that the Physicians are great Cheats, and envious persons, for continuing such flat Medicines, and not recommending to the World, or rather their Shops, our greater secrets. The answer is easie, that the Medicines in our Pharmacopæa, are the best of any other Pharmacopæa in the World, both for their goodness, and well preparing of them, whether they be Chymical, or Galenical; and therefore the same scandal will ly on all Pharmacopæa's whatsoever. Secondly, I say that within these few last experimental years, the practical part of Physic hath been much improved (as well as Anatomy) especially by such as have put their hands to work; and therefore till such improvement, this could not be well amended. Furthermore, in making new Dispensatories, a full content must be had, and 'twere not fit to move where the motion were not like to take place, for though private men invent new ways of compounding and preparing, and using their own invented Medicines, yet 'twill require a long time to make them publickly known, and brought into common use, and till that be done 'tis not possible to have them brought into a common Dispensatory; besides, no man would make a motion for such a reformation, unless he were well furnished with specificks, and then 'twill be required of him to expose them to the whole World, which how incongruous it will be, every man may easily conceive; hereto add, that the Apothecaries think themselves able enough by this present Dispensatory, to out-beard Physicians, and do publickly profess (as hath been said) that they understand the practice of Physic well as they; how much more would they have said so, if they had been made
