aloe is what did it for me. i have some ingestible pure aloe gel, and put it on there probably 10 times yesterday when I had a nasty canker sore on the underside of my tongue that had been developing already for a few days. I was desperate cuz it was SO painful I could hardly talk. maybe Im a wimp. Anyway, that's all I did and had a good night sleep. Today I hardly feel it at all.
Aloe Vera is very helpful in the healing process, as is sodium lauryl sulfate elimination.
