Cornmeal Fights Nail Fungus

Q. I clipped your article on a cornmeal cure for nail fungus but mislaid it. Not knowing the proportions, I cooked some up and soaked my nails. Even done wrong, it helped mightily. Please forward the correct recipe, which my doctor and his nurse also want.
A. A listener to our public radio show shared the following remedy for nail fungus: “Put about an inch of cornmeal in a plastic dishpan. Pour in hot water, stir it so the cornmeal gets dissolved and when it is cool enough not to hurt, soak your feet for an hour. Done regularly, this will get rid of the fungus.”
There is no scientific data to suggest this recipe works, but gardeners report that sprinkling cornmeal around roses may discourage black spot fungus.
