Good for you! I am a huge fan of Manuka honey which is well known to most Australians and Kiwis. Manuka is the Kiwi name for the tea tree. The oil from the leaves is also used for its antiseptic properties (mozzie bites, and cleaning mould and mildew off the tiles).

The honey has been studied for treating leg ulcers that I know of and it outperformed the standard dressings during the trial. I believe there is also a trial to look at mouth ulcers at the moment.

I love the tips for using it when your mouth is in really bad shape and offer one more possibility. You can water it down a bit with water, swill it about and then either swallow or spit. Maybe that won't sting quite so much? If it does, at least you know you can put it away and use in on your oatmeal when you are back to eating
