My wife makes plantain salve. Good for any kind of skin issue, blisters, wounds, scrapes, bug bites/stings, diaper rash, etc... Helps healing faster. It's made from a common 'weed' (not bananas) that we can find just about anywhere (here is Wisconsin, at least). Here is a recipe for making it. My wife makes it a little different, but don't have her specific version handy, but it's close enough. I've used it for all kinds of issues over the years and it really works.
