Q. My 7-year-old grandson has warts on his toes. He’s been to the doctor with no luck. What can I use to treat this?
A. One approach is to cut a piece of banana peel about the size of the wart and tape it on overnight. A new slice of banana skin nightly (white part touching the skin, yellow part out) may clear warts in a couple of weeks. Others have reported success by painting the warts with castor oil, vinegar or the white juice from a broken milkweed stem.
