CankerMelts are a new product for healing (surprise!) canker sores. They are time-release discs that stick to the inside of your mouth and heal canker sores in 1 to 5 days, using an extract from the root of the licorice plant. You can learn more about CankerMelts here.
I have one box of CankerMelts to give away to the first reader who emails me at cfoblog [at] gmail [dot] com with their mailing address.
