You might look into it to see if there’s something special about butter versus other oils/fats that may make butter specifically good for burns, but I understand that as keeping the air off of the burn, similarly to how oxygen tents work.
Today we apply petroleum jelly (Vaseline, Neosporin, etc.) over skin to help it heal, but butter is basically going to do the same thing of keeping in moisture.
I think the reasoning with topical coatings for burns is actually something to do with avoiding gases touching the burned area, which is why they use oxygen tents for people with severe burns over a large area. Petroleum jelly and other similar products block the air from touching the burn also.
I find that oils such as petroleum jelly or olive oil do provide pain relief for burns. I can only speculate as to the method of action, but I’m clearly not the only one. Apparently even air movement or contact can cause pain to burns due to the exposure of the dermis, and possibly other reasons.
> Also, oxygen's a gas.
Yeah, I think it must be carbon dioxide or some other gas that is naturally occurring in the atmosphere that causes the painful sensation, otherwise they wouldn’t use specifically oxygen?
"HBOT helps wound healing by bringing oxygen-rich plasma to tissue starved for oxygen. Wound injuries damage the body's blood vessels, They release fluid that leaks into the tissues and causes swelling. This swelling deprives the damaged cells of oxygen, and tissue starts to die. HBOT reduces swelling while flooding the tissues with oxygen. The higher pressure in the chamber increases the amount of oxygen in the blood. HBOT aims to break the cycle of swelling, oxygen starvation, and tissue death.
HBOT prevents "reperfusion injury." This is the severe tissue damage that happens when the blood supply returns to the tissues after they have been deprived of oxygen. Blood flow can be interrupted by a crush injury, for instance. If this happens, a series of events inside the damaged cells leads to the release of harmful oxygen radicals. These molecules can do damage to tissues that can't be reversed. They cause the blood vessels to clamp up and stop blood flow. HBOT encourages the body's oxygen radical scavengers to seek out the problem molecules and let healing continue.
HBOT helps block the action of harmful bacteria and strengthens the body's immune system. HBOT can disable the toxins of certain bacteria. It also increases oxygen concentration in the tissues. This helps them resist infection. And the therapy improves the ability of white blood cells to find and destroy invaders.
HBOT encourages the formation of new collagen and new skin cells. It does so by encouraging new blood vessels to grow. It also stimulates cells to make certain substances, like vascular endothelial growth factor. These attract and stimulate endothelial cells needed for healing."
That explains why they use oxygen tents, but it doesn’t really explain why oils/fats on burns provide pain relief. The little I was able to determine was that the exposed inflamed dermis is extremely sensitive to touch/pressure even of just air or air currents, but I don’t know why this is the case.
