I've known honey was an antibacterial and you could use it on wounds in a pinch, but I hadn't yet heard that they are actually starting to use it in hospitals as a salve for wounds. It sounds like they are getting a lot of good results from it. Note that the honey they use is an Australian/New Zeland variety that's more potent than standard American or English honey.
Before the introduction of sugar in the middle ages, tooth cavities were pretty much non-existant in medieval Europe. That's because cane sugar feeds the bacteria that decays teeth and makes them more agressive on our teeth, whereas honey kills the bacteria and therefore causes LESS tooth decay.
My question is: if you consume honey, can it kill bacteria in your stomach and/or intestines, or does it get broken down before it gets in there? If it were in a pill form, would it work better? I think some people on here see holistic doctors, so I think this would be a question for them. If it could help with bacterial problems in the digestive tract, then (unless you are diabetic) it might be worth trying.
