Alum for Canker Sores = WORKS!
I saw some guy on youtube say that he uses Alum on his canker sores. I get the worst cankers. They always manage to come in a painful constellation that prevents me from eating comfortably. But I tried this, and it worked really fast. The morning after my first use, the sores had significantly shrunk and were beginning to re-epithelize. The second morning? Healed. No pain. And I'm eating a donut without tears. This "rumor" works!
