To escape chilblains, avoid getting the feet wet. Should they become damp, change shoes and stockings at once. Use woolen stockings and avoid toasting the feet before the fire. Chilblains are frequently prevented by bathing the feet in a strong solution of alum. With the first indications of the chilblain, as revealed by the itching sensation, it is well to rub them with warm spirits of rosemary, adding to the same a little turpentine. Lint soaked in camphorated spirits, opodeldoc, or camphor liniment, may be applied, and retained when the part is affected.
It is claimed, also, that chilblains may be cured by bathing the feet in water in which potatoes have boiled."
