This form of disease sometimes attacks all parts of the body, but is usually confined to the face and extremities. The inflammation appears in a small spot, and gradually spreads to a greater or less extent over the surrounding surface. When confined to the face, the symptoms are sometimes violent, swelling so as to close the eyelids. On the fourth or fifth day, blisters of different sizes make their appearance on the inflamed surface, containing a clear and watery fluid which afterwards becomes of a straw color and more or less glutinous. In twenty-four or forty-eight hours the blisters break, when the redness and swelling begin to subside, and the adjacent cuticle peals off in the form of scales.
In mild cases of this form of disease, a tea of meadow fern, taken freely and used for bathing, is all that is required. In more severe cases, composition and injections should be used, and if necessary a full course of medicine, repeated as occasion may require. A poultice of slippery elm will soothe the irritation and relieve the pain.
