Sneezing frequently occurring in fevers is troublesome, for it determines
to the head and weakens the strength, and, in some cases, it produces a
discharge of blood. Such are the bad effects of sneezing, which ought
therefore, to be contended against. It is restrained by rubbing the nose,
forehead, and eyes; by yawning, frequent friction of the roof of the
mouth, eructation, stretching of the loins, raising the head, turning
to the side, gently chafing the extremities, anointing the masseter
muscles, pouring hot oil into the ears, applying a warm cushion under the
chin. It is proper to avoid being roused suddenly from sleep, and also
smoke, dust, acrid smells, pepper, castor, mustard, and mint. The smell
of apples and polenta is proper, for it blunts the desire of sneezing.
The empty sea-sponges do the same. When there is a frequent desire of
sneezing without the ability, let the lips be composed, let the patient
smell to acrid substances, and let the mind be relaxed.

COMMENTARY. Galen explains that sneezing is a still more violent effort
of nature than coughing, and that its intention is to remove irritating
matters from the parts about the nose. (De Caus. Sympt. ii, 4.)
Avicenna gives ample directions for the treatment of sneezing; but they
are evidently copied from our author. (iv, 1, 2.) The same may be said
of Haly Abbas. (Pract. iii, 22.) Rhases recommends us to give warm gruel
internally, to pour warm water on the head, and to apply oil of gourd, of
roses, and the like, to the nostrils. (Cont. xxxi.)
Cassius Medicus discusses the question why rubbing the nose and eyes
stops sneezing. He supposes that it is by occasioning a discharge from
these parts, whereby the exciting cause is removed. (Probl. 45.)
