To prevent frostbite on fingers and toes, sprinkle cayenne pepper into your socks and mittens before going outside.
If it’s not cold in your part of the world right now, you might want to prepare this frostbite remedy well in advance of the next winter: Soak 2 tbsp of whole black pepper corns and 1 tbs of ginger roots and horseradish, both coarsely grated, in 1-1/4 cups of white wine for a week. Filter, strain, and store away in a tightly stoppered bottle in a cool, dark place until the next winter. In case of frostbite, apply the solution generously with a brush on affected parts.
