Hi Gillian,
I don't know about the rest, but I can give you a bit of a run down with my personal experience with Honey.
My foal was at a stud with his mummy and severely injured his hind leg. He lost the skin from his hock to his pastern (don't ask me how, the people don't seem to be able to tell me either).
Anyway the people were treating him with traditional methods, sprays antibacterial stuff, dressings, etc. The wound was about one month old and I eventually said I was coming to pick him and his mother up regardless (they were saying he was not fit enough to travel). The people had treated him that day and told me his wound did not need dressing for at least another 5days.
3days later I could not stand the stink! The vessels etc looked like they were dying. I made the decision then to use the honey the honey man had paid us with for letting him keep his bees on our place as we had huge quantities of it and I knew it was straight from the bee.
I washed his wound thoroughly (there was no pus just a foul smell and a huge amount of swelling) then pasted honey all over his wound and put a clean dressing on it. I was a bit worried as it was not Echinacea honey just normal eucalyptus honey.
Three days later I took his dressing off and could not believe my eyes. The wound had started weeping a tonne of pus (but did not smell as bad and the swelling had gone down) and once washed there was a pink glow to his wound instead of a pale dead look. The process has been repeated every three days since, (now for three weeks) and there is now signs of active blood vessels and slight regrowth of skin both at the top and bottom of the wound. I now have a bit of hope that he will be fine, time will tell.
This is for your information only, I am no expert I am just letting you know my experience.
