CHAP. XV. Of Medicaments called Errhines.

IN long diseases of the head, proceeding from flegm, after universal evacuations, Errhines are used, which draw it down and purge it away through the nostrils.

Those evacuations which empty the whole body of humours are said to be uni∣versal, which are succeeded by those, which evacuate only a particular part, and are therefore called particular: such is that, that brings down flegm from the brain through the nostrils, most convenient in many affections thereof, for after most part of the excrement is drawn away by universal evacuation, the remaining part is best evacuated through the near adjoyning places.

And that they may more easily draw down this thick and cold humour, they ought to be hot, attenuating and cleansing.

Such are these that follow:

• Roots, of Orice, Cyclamine, wilde Cucumer.
• Leaves, of Beet, Colewort, Pimpernel, Marjoram, Sage, Betony, Penny-royal, Organy, Horebound, Ivie, Tobacco.
• Gums, Euphorbium.
• Juices of the roots, and leaves of the aforesaid Herbs, Elaterium.
