I had a mosaic/cluster plantar wart for almost 5 years. I didn't try to get rid of it for about 2 years, as I read that it would likely go away on its own and it wasn't really painful. But, instead it grew and spread even to other members of my family. At that point, I tried salicylic acid (gel and pads), using multiple brands, as well as two treatments with cantharidin (beetle juice) administered by the podiatrist. The latter was extremely painful, and I needed crutches for a few days after each treatment. All in all, the doctor and over-the-counter treatments probably cost me over $300 and a lot of frustration and pain.
Ready to give up, I read about the banana peels. I kept fresh banana peels on the wart 24/7 for about 4 days and then changed to nights only for the next 3 days. I would change out the peels every 12 hours and always ate the banana that I used to get the peels. Well, whatever I did, it worked! I noticed within 3 days that good things were happening to the wart...it looked more dried out. And, then I started to see beautiful fresh pink skin start to appear where I'd not seen nice skin in years. It was the coolest thing ever. Three weeks since I did the treatment, I have no sign of wart and my foot looks perfect. It was a truly amazing thing and made me a believer in at least trying "natural cures" before some of these other things, at least for plantar warts!
