In the behind the times days, why did populace put crude meat over a bruise? Is it simply to cool it?

A few books I have read in the region of medieval times suggest putting raw meat (generallt red meat) over a bruise to minister to it heal. It is largely on the face. I be wondering whether there be a scientific use or whether it was lately to reduce the swelling as they didn't hold frozen peas in those days. Something to do next to zinc or iron in the meat possibly? It's just I thought they salted meat to preserve it as they have no cooling devices. You are correct, they had no cooling devices such as frozen peas. But it wasn't the cooling effect of the natural meat that was expensive. It was believed that the untouched meat would act as a poultice and 'draw out' the inflammation and excess blood contained by the bruise.
It must have worked to some amount because it was member of folk medicine for hundreds of years and even today, tons boxers use a slab of beef to clear up a black eye.
I think so
to keep hold of swelling down
they used it cuz it's so cold it actually keep tissue down so it don't swell
summin 2 do wiv the juice from the meat
Sa far as I know it be there euivalent of putting rime over a bruise like we do today.
untouched meat has deeply of juices that sustain heal the body, frozen peas don't do you any polite there
