There is a growing body of medical literature showing the effectiveness of honey (in particular, types like Manuka honey from New Zealand) on wound healing, particularly slow healing wounds. The properties of the honey can vary quite a bit with the pollen used to make the honey, so stick with something like Manuka to get the full spread of benefits, like antibacterial properties. Some of the case reports in the medical literauature are pretty amazing. Certain ulcers/wounds that haven't healed in six months of intensive treatment suddenly starting to "pink up" and begin healing after just a few days of Manuka. It's not a magic bullet that will miraculously cure every stubborn wound, but it does seem to be much more than just an old wives' tale.
There is at least one company that has developed an actual commerical, honey-impregnated bandage that makes chronic wound care with honey much more convenient. I heard about it on the radio not too long ago. I wish I could remember the name of the company. IIRC, they're using this bandage at one of those specialized wound care centers mentioned in the radio segment...maybe at Lennox Hill Hospital in NYC?
