Can Green Beans Cure Canker Sores?

Q. For over half a century, my family has been curing our canker sores quickly and easily. Just this week, I bit my lip during sleep and the spot kept growing. When the sore was 2/3 inch by 1/4 inch, I decided to cure it. By the next day it had shrunk to a short thin slit and soon no sign remained.
The cure is to eat a can of green beans. We used to have Gerber’s strained green beans but we can no longer find this product. Whatever the active ingredient is, it works really well and tastes a lot better than the sauerkraut juice you have mentioned before.
A. Green beans are about as innocuous as any remedy we could imagine. Gerber still makes strained green beans.
Others have reported success with two tablespoons of sauerkraut juice swished and swallowed morning and evening. Another remedy is baking yeast. Put some powder on the sore and allow it to dissolve.
