Having read Dave from Fountain Inn's brave experiments with Papaya (in the name of science, of course. (Have you lost those extra pounds, or are they there as a living testament to your brave pioneering spirit??!! ) I discovered a bag of Papaya leaf tea here and decided to try it for recurring Canker Sores. After waiting for three outbreaks, all of which were cured with the tea, I am happy to report that fact here. The relief from pain takes about 2 days of 1-2 teas daily (1 tsp. tea leaves in a cup of boiling water. Either boiled for a bit, or just left to steep) and the cure depends on how strictly I stay away from my triggers (certain baked goods, bananas and more than my tolerance level of citrus).
