Take one part of gentian-root, two parts of centaury, distil them with ale in an alembic after you have bruised the gentian-roots and infused them well. This water is an admirable remedy to provoke the terms. But if you have not this water in readiness, take a drachm of centaury, and half a drachm of gentian-roots bruised, boiled in posset drink, and drink half a drachm of it at night going to bed. Seed of wild navew beaten to powder, and a drachm of it taken in the morning in white wine, also is very good; but if it answers not, she must be let blood in the legs. And be sure you administer your medicines a little before the full of the moon, by no means in the wane of the moon; if you do, you will find them ineffectual. If barrenness proceed from the overflowing of the menstrua, then strengthen the womb as you were taught before; afterwards anoint the veins of the back with oil of roses, oil of myrtle and oil of quinces every night, and then wrap a piece of white baise about your veins, the cotton side next to the skin and keep the same always to it. But above all, I recommend this medicine to you. Take comfrey-leaves or roots, and clown woundwort, of each a handful; bruise them well, and boil them in ale, and drink a good draught of it now and then. Or take cinnamon, cassia lignea, opium, of each two drachms; myrrh, white pepper, galbanum, of each one drachm; dissolve the gum and opium in white wine; beat the rest into powder and make pills, mixing them together exactly, and let the patient take two each night going to bed; but let the pills not exceed fifteen grains. If barrenness proceed from a flux in the womb, the cure must be according to the cause producing it, or which the flux proceeds from, which may be known by signs; for a flux of the womb, being a continual distillation from it for a long time together, the colour of what is voided shows what humour it is that offends; in some it is red, and that proceeds from blood putrified, in some it is yellow, and that denotes choler; in others white and pale, and denotes phlegm. If pure blood comes out, as if a vein were opened, some corrosion or gnawing of the womb is to be feared. All these are known by the following signs:
