I remember reading that leeches are still used in some eye surgeries, some plastic surgeries. The Brits stuck in prison work camps in Burma used them to eat away gangrene.
Good point but it reduces the point I was making so stop making good points like that:)
What will you tell me next? That groups of guys still get together 5 or 6 times a day and sniff each other butts while "praying".
I don't think that is technically correct. They may have used leeches, but not because the leeches would remove dead gangrenous tissue, but because the leeches would aid blood circulation, thus preventing gangrene (with a lot of luck). Leeches, like mosquitoes, can locally disable clotting and ensure a continuous trickle of blood from a wound.
