The purging Opiate.

WHat it is (& its differences) may be sought in the purging Apozem and potion.

Here I shall at present account it twofold, Ma∣gisteriall, and officinall.

What a Magisteriall is, see in the purging syrup.

Neverthelesse three things are to be consider∣ed, the composition, use, and Utility.

As to the COMPOSITION, 'tis prepared, 1. Either of powders onely taken in syrup, or ho∣ny, or both together.

These powders are every where chosen out of purging Simples (and sometimes may be in use the spices of purging Electuaries) together with their fit correctors, both Simples, and com∣pounds, as also their directors.

As to the quantity, these sorts of purging powders ought to be prescribed, according to the number of doses for which you desire or in∣tend your Opiate; as if you desire an Opiate for six times, you must prescribe six doses of pur∣gers in substance, adding also their correctors; as to the quantity of that they are made up withall, they usually, though ill prescribe it, q. s. as is be∣fore noted in the purging syrup; for as it is there said, the quantity of these is also to be defined, and its proportion ought to be three or four times the weight of the powder, and that expressly to be set down, that you may be certain of the dose.

Note also, that when Cassia or other things which have the consistency of hony, are added, they are to be accounted instead of so much hony.

2. Or seeing that now they are very seldom made of powders onely, they are usually prescri∣bed of officinall purging opiates, Cassia being al∣so added, where we would purge more gently; or else there is also added a solid purging Electuary of the shops, together with a purging powder, and their correctors; all which are to be taken in a convenient syrup:

And this is their proportion.

To an ounce of opiate you may adde a dram or two drams at most of a purging powder.

But for the most part, four ounces of these sorts of Opiates are required, and then the dose of the syrup is not defined, for there is need but of ve∣ry little.

3. Or onely of the softer sort of purging sim∣ples, as Cassia, tamarinds, manna, pulp of prunes, raisins, or Sebestens, with their correctives, when you would onely lenifie; and if you would yet purge more, you may adde the simple purging powders in the proportion aforesaid.

4. Or else with all these together, as the leni∣fying Simples, officinall Electuaries, purging Powders, together with the aforesaid proportion of syrup.
