I have quite often used manuka honey on infected wounds that don't respond to povidone iodine (Betadine). Usually it works very well - there is some extra antibacterial ingredient other kinds of honey don't have. Whan it doesn't, the next step is oral antibiotics.

Marion here had a nasty dose of oozing cellulitis a few months ago and it took three successive different types of antibiotic to deal with it - together with gel dressings like the ones Spaw described (though with the amount of ooze, they needed changing twice a day).

Manuka honey works very well on genital herpes.
