He may so contrive his Medicines, first, That they may be taken in small quantity, and be made more grateful to the tast, and stomach, and perform more then those of the Apothecaries, commonly slovenly made, and of themselves Fulsom, Nauseous, and Sluggish. Secondly, His Medicines made for particular persons, may last Weeks, Months, nay Years, whereas the Apothecaries Drinks, especially in the Summer time, must be renewed once, or twice every day, to the excessive charge of the Patient. That his Medicines may be fewer, is evident in Physicians that practise in the Country, who ride far to Patients, and carry in their Mans Cloak-bag, Medicines enough, not only for the person he is sent to, but also for most other persons, and Cases he meets with in his Travels, and therefore his Closet needs contain but few, yet noble and generous Medicines, and such as may serve him upon all occasions, supplying what's defective from the Fields or Gardens. He may avoid all pompous, useless, chargable Medicines of the Shops, and substitute in their place, cheaper, and more conducible to health; He may very well lay aside the precious Stones, Saphir, Emerals, &c. the high priced Magistrals of Coral, and Pearl, made worse by their preparations, or rather destroyed thereby in their Virtue, as also Unicorns Horn; and Bezoar, all which are now rarely used alone, but in the received Compositions; He may also spare the charges of leaf-gold, for guilding Pots, Glasses, Pills, Electuaries, Boles, &c. which serves only to raise the Bill. He may teach the Patients facile and easie Remedies, as to make a Clyster, apply Blisters, or Medicines to the feet, where they are needful, &c. and in many Cases may cure by well ordering his Patient only, without any Remedies at all, or but very few; being free to act for the Patients Health, without the grumbling of the Apothecary; and many other ways he may daily meet with, very advantageous to the Patient. He will have little use of Conserves, Syrups, Lohocks, &c. a greater part whereof Sugar makes up, which doth more hurt to most persons, then the other ingredients do good. As for Infusions and Decoctions, he will find by experiment, how much liquor, or Menstruum will suffice to extract the full vertue of the ingredients, and what are helps, or hinderances thereunto, and thereby neither suffer loss in the quantity, or quality of them.
