Wart Removal Home Remedy

My oldest had warts all over his hands when he was young...probably 50 to 75 at a time. We had taken him for cryotherapy, had the warts injected so he could make antibodies against them, over the counter remedies but nothing worked. We were getting ready to take our son to an immunologist when a friend suggested an old remedy of her grandma's. Boil a few eggs in a pan. Save the water, let cool till still warm and soak effected area in the water the eggs were boiled in. Soak till the water is cold. Take an emery board and file the dried wart, cover with tape. Do this on a daily basis. It took us less than 1 week to clear them all. He has never had a recurrence!
