Take 4 purple potatoes. Boil, and mash them. Take an egg white, and 1/8 cup of olive oil, and add this to the mashed potato. If available, you can add a few drops of peppermint oil. Apply this only to the bottoms of your feet, and be sure that you do not have any cuts, or scrapes on your feet. After 45 minutes, remove this from your feet, and soak your feet in warm water for 5 minutes. Repeat if necessary.
