222. Paritaria: i.e. pellitory of the wall; hot and dry in the fourth degree; this herb is called vitriora, ‘vitrum’ being glass, because it will clean glass if rubbed on it; it is better fresh than dried; it has the attenuating, dissolving and corroding virtues; it serves well against pain and windiness of the stomach and intestines, and against stranguria and dysuria. If it be boiled in salt water and put on the navel, it will greatly relieve the illnesses we have mentioned. Item, if this herb be pounded and boiled with bran and tartar and applied as a plaster to the navel, it will stop the flux of the abdomen. If a bath be made of this herb, foliage of Traveller's Joy, lichen and roots of madder, and people with dysentery be put in it, it will greatly relieve them, as we said before.
