Many years ago I had a friend who told me she found using the inside of a ripe banana peel helps with itching for bug bites, poison oak, shingles, icthy skin. I have tried it and my aunt used it for her shingles and it worked.
Just google it if you want to learn more. But it is nature at its finest. I just love all natural. The oils in it act as a natural inflammatory and pain reliever.
Give it a try. It hopefully will work and you have nothing to lose but alot to gain.
Good luck and let us know if it does work. Now remember make sure the banana is ripe enough when it is gummie on your skin and it will stick. You don't want to wash it off. She put it on like a paste.
