Apparently, so i've heard the inside of banana skins work on warts and verrucas.
Never tried it myself but my friend did, and it worked for her. Not sure over what amount of time though or where she headr this.
Basically she scraped some of the stuff off the inside of a banana skin and put it on her verruca then covered it with a plaster to hold it on and wore it to bed every night so it wouldnt come off like it could if you done this in the day.
Maybe be worth a try, but sound a bit yuk now i'm reading this back! lol
But hey you never know.
one good idea can change your life!
