One time when I got real run down I got a mouth full of canker sores, My GP told me to drink a quart of buttermilk a day and they would go away. It didn't work but by the end of the first week I was addicted to buttermilk. I finally went to Austin Diagnostic Clinic and they prescribed some mouthwash with tetracycline in it. The canker sores disappeared in a few days.
