Why would you use a leech instead of a needle or something? What are they for
Not OP, but apparently they're useful for when you want a continuous, slow drain of blood. The ones they breed for hospitals don't carry disease, so you can just kinda plonk it onto the spot that you want blood out of, and replace it when it gets full
Wait until you find out what they still use maggots for...
what the fuck? why do they use that?
They're really good at eating dead rotting flesh?
like dead body's?
Nope:

does it tickle when they eat you
As per above source:
Some other good FAQs:
heartwarming
Definitely woundworming and not heartworming
Burn victims
It's less about the blood they suck out and more about their saliva. It's a natural anticoagulant.
Amputation sites I think? The suction attracts blood flow to the area and supports healing/retention of blood vessels... I think. Neither one of us clearly can be bothered googling but that's what I recall...
google makes things too easy. great thinks were thunked back in the day where people had nothing but their own minds to consult.
And bad thunks are thinked just as much now as then. Truly the worst of times
For skin grafts after burns; the leeches' saliva has anticoagulants that helps blood flow through the microvasculature (tiny blood vessels) of the area. This helps promote growth of new blood vessels, as well as improve the health of the current blood vessels in the area.
TLDR: Helps tiny blood vessels in skin grafts (and other procedures), reduces failure of said skin grafts
If anybody's wondering if there aren't more modern medicines and treatments...
Yes, but leeches are cheap and does the job just fine
Others have already mentioned limb reattachment and anticoagulants, but if you're interested in learning more, I highly recommend a book called Dark Banquet: Blood and the Curious Lives of Blood-Feeding Creatures. Leeches, mosquitoes, bedbugs, and vampire bats are fascinating!
