My son started to develop a canker sore the other day. These dreadful things feel like a mini fire, so I took action before it got very bad. He put this mixture on the canker sore and let it dissolve. He did this multiple times for a few hours, as soon as the mixture dissolved, he added more. By morning, I could hardly see where it was the night before.
1 tsp raw unfiltered honey
1/2 tsp orange peel powder
Apply and let dissolve.
Reapply as soon as the previous application is gone.
