[YEA] I had started taking apple cider vinegar twice a day, and after two days noticed the beginning of a canker sore. It didn't hurt yet, so I checked this site, then went out and got some Alum in the grocery store. I did as someone else suggested and wetted my finger, then dipped it into the alum, and then held it on the canker sore for about 5 minutes. Because I caught my canker sore so early, it didn't really sting at all.
I did that twice the first day, and again twice on the second day. It never hurt at all, and it got a little larger at first, but then started receding, and now 4 days later, its basically gone! I'm so happy with the Alum cure! I used to spend a whole week in agony thinking there was no way to help it- I love this website!
