I’m honestly not sure. I know honey is bacteriostatic, so you can use it as an antibacterial salve on minor wounds. As for actually sealing a wound? Especially one with deep trauma. I’m skeptical. This would be (almost exactly) like trying to treat a gunshot wound with Neosporin. Yeah, it’s great for minor cuts or mild burns, but against a bullet, not so much.
If this is after field surgery to keep the wound from getting infected, it’s a lot more plausible, but not just, “boil and pour it in there.”
My recollection is that boiling honey breaks down the enzymes that make honey bacteriostatic, which is vital to preparing it for fermentation into mead. …but, the internet say I’m wrong, that you can get honey to ferment at room temperature if you cut it with enough water, and that there’s no enzyme function involved.
I suspect that, as with a lot of organic mater, your body can pretty safely absorb it during the healing process. So, getting it out of the wound is a lot less important than you might think. That said, if you do need it out of the wound, you can wash it off, which you need to do when cleaning most wounds.
Well honey’s bacteriostatic properties come from two things. First of all honey is simply too highly concentrated to allow any bacterial growth. The second is through hydroxide radicals, though I’m unsure how these are formed.
Since honey consists in large part of sugars, it will start to caramelize when heated, as well as the water will be evaporated. Once it cools down again it should become solid. In that sense it does sound plausible that you could seal a wound with it. It doesn’t sound like a very good idea though.
Given my first hand experience with sugar burns, I’m adding that to the list of things I never want to try.
