  • It has helped so much, I wish others knew more about it. I've had very few sores, and they were gone within a day, two at the most. That's amazing to me when they normally would last 10-20 days and be very large and painful.

  • Since I’ve been taking Cankerboy, I’ve not only had fewer canker sores, but the ones that do appear go away in a day or two and never become painful.

  • I have to say it seems to really be working now that I’ve been on it almost 60 days. Haven’t had one since the first two weeks.
