Yes, two people in my family have gotten rid of toenail fungus with cornmeal soaks. Use the directions on the website. Basically, you soak cornmeal in enough warm water to make a thick paste, let it sit for a while, then add enough warm water to make it into a slurry and warm enough to be comfortable. Pop a fun DVD or tape in, sit down and spend an hour or so soaking. Rinse off, dry and repeat the next day if necessary. One family member was "cured" in one soaking, the other took two. No matter how many it takes, it's better than synthetics that destroy your skin, your liver or both!
Cornstarch is a staple in my house, and I've treated my feet with it to great success. Just a powdering makes such a difference when I have to wear boots for months at a time! My feet are in much better shape these days from getting a friendly cornstarch treatment when I wear closed-toe shoes. I've had bouts of what was probably athlete's foot and gotten rid of it with just a cornstarch application or one application of tea tree oil followed by cornstarch. Each time, it went away in less than 48 hours.
Hope that helps!
