“Back to leeches and maggots, it seems.”
I’ve heard that leeches are sometimes being used now. Something to do with clotting of the blood (IIRC).
They use them to get the blood flowing on severed limbs and digits. But first they use sterile maggots to clean the areas to be reattached as they tend to eat the dead and rotting flesh before the live tissue.
Ah science!
