155. Isopus: i.e. hyssop; hot and dry in the third degree; it serves well against the cough that comes from coldness, and against roughness of the voice, and phthisis. Item, if hyssop, dried figs, and honey be boiled together and drunk, this will help with every illness of the chest. Item, if powder of hyssop be boiled in honey until thick, and a spoonful of it be drunk every day, this will help with every illness of the chest. Item, if hyssop and garden cress be boiled in oximel, it will expel the viscous phlegmatic humour, and it will help with windiness of the intestines. If hyssop be boiled in vinegar and a sup of it be held in the mouth, this will help with toothache. If hyssop be burnt, and the fumes allowed into the ear, it will help with illness of the ears. If hyssop be pounded and boiled in water together with anise, and put as a plaster on a part of the body that has become blue from a blow, it will give it a good colour. If the same herb be pounded and wet with warm water, and given hot to the woman who is suffering birth-pangs, she will give birth to a baby promptly; according to Avicenna, it has the cleansing, attractive, consuming, and dissolving virtues; Avicenna says that the virtue of this herb is mostly in its flower and foliage, and not in its root or stem, as we have said.
