Lemon. Because of its potent acidic base, lemon is another powerhouse for healing multiple body ailments. To rid yourself of a corn, peel down the lemon and use a small piece of the pith to place over it – the piece needs to be just large enough to cover the problem area completely. Continue this process every night before bedtime and remove the pith once you wake up. The corn will gradually disappear within a week or less. For callus removal, soak your feet in a concoction containing warm water, a half cup of baking soda, and about three tablespoons of lemon juice before scrubbing them with a pumice stone.
