Good to know. Also, I wanted to add that 2 weeks ago my brother had canker sores in the back of his throat which hurt so bad that a sip of water felt like a knife. He sucked on licorice lozenges from the health food store, and within one to two days the sores were gone.Replied By Randomhelpguy (Colorado) on 03/22/2014
Take an ice cube with frost still on it over the canker sore and it will rip off the white part, and numb it at the same time. Then take hydrogen peroxide and hold it on the sore mixed with Apple Cider vinegar for up a minute or two. This will sting like a bitch. After all this take a Q tip and activated charcoal and scrape the crater from the former sore. Then take just the charcoal and make a paste and leave it for a few minutes. Problem solved overnight or at least smaller. Or alternatively you could use alum which also burns like hell.
