Hay Fever

a distressing affection of the mucous lining of the eyes, nose, mouth, throat, and bronchial tubes. It is brought on occasionally by intense mental agony, but is due, for the most part, to the inhaling of a poison-making pollen from certain plants. It appears at the haying season or in the autumn, and has been attributed popularly to the pollen of goldenrod and ragweed. Eminent medical authority, however, assigns the cause to the pollen of certain grasses. The utmost endeavors to produce symptoms of hay fever with other pollens have failed, but the pollen of a number of grasses produces a slight attack, which, by way of inoculation, prevents the occurrence of the disease. The readiest cure for hay fever is residence in mountainous or pine forest regions.
