As for stickiness, the tongue is rubbed with a reed or willow twig, anointed with almond oil and candy sugar, until it is clean, or with a sponge with a little salt and rose oil; the patient receives great relief from this. If the tongue is rough, not from stickiness, but from dryness, the patient should keep cordia or a plum pit, or salt, which is brought from India, in his mouth. It has the color of salt and the sweetness of honey, and is taken, as Archigenes states, about one bakilla. Quince seeds are one of the medicines that moisturize the tongue and prevent it from drying out. The patient should not open his mouth often and sleep lying on his back - both of these dry out the tongue.
Sometimes persistent sneezing brings great harm to those with a fever: it torments them, fills their head with juices and weakens their strength, and often causes bleeding from the nose. You should rub their forehead, eyes and nose, make them open their mouth and rub the roof of their mouth with force. They pull them by the head, turn them over, knead their limbs, pour oils heated to a slight warmth into their ears, moisturize their muscles and jaws. Heated pillows are placed under their heads, they are not suddenly awakened from sleep, they are protected from dust and smoke and from everything that has a pungent odor, and they are made to smell oatmeal, success clay and sea sponge.
