In the past when I have had a wart, I went to the Doctor to have it removed with an electric needle. Sometimes this left a scar.
I went on line to find a cure and tried the one using apple cider vinegar. Simply tear a small piece of cotton and saturate it with the apple cider vinegar (it doesn't have to be organic or unfiltered). Place the cotton ball directly on the wart and tape it on. Do this before bedtime and remove the cotton in the morning. The wart should completely disappear in a week to ten days.
I was amazed at how well and quickly this worked.
