A Bolus hath that name because it is a gobbet of Physick in a round figure, * 1.1 allmost as much as ones mouth will hold, whence it is calied Buccilla; but the name of Bolus agrees not only to purging, but altering Physick.
Purging Boles are thus prepared: * 1.2 purging Electuaries are taken, and a convenient quantity of Sugar being ad∣ded, they are made up in the forme of a Pyramid, not much unlike an Olive, lest they should be loathsome, they ought not to be made of Electuaries that are ungratefull, and for that reason Hiera is scarce ever given in Boles; the quan∣tity ought not to exceed an ounce.
2. Sometimes some of the Powders or speties are ad∣ded.
3. You may add conserves.
4 Or instead of Sugar Conserves either alone, or with a little Sugar may be used.
5. Instead of Sugar, or sometimes with Sugar, especi∣ally in diseases of the reines, Licorish-Powder; or some o∣ther may be added, so may Turpentine also.
6 Moreover in the stead of purging Electuaries, Powders of simples that purge use to be taken, wherein something also which alters, or corrects the violence of purgers, or that give a pleasant ••mell or taste to them; or else they may be added for some other cause, or species of purging Confections, or Extracts purging, both simple and compound, which are taken and incorporated with the pulpe of Cassia, the pulpe of Tramarines, or Pruants, or some Conserve or Rob, or some convenient Syrup, and with a sufficient quantity of Sugar are made into the forme of a Bolus.
7. Sometimes distilled Oyles are ming lediwith a Bolus to corroborate, namely of Anniseed, Mace, Cinamon, Cloves, some few drops, and sometimes the Bolus is covered with Gould.
