Leaches are FDA approved for medical use.
Primarily to help relieve blood pooling until new veins develop and restore circulation, and for venous congestion after reconstructive or microsurgical surgery
They’re harmless, and can be easily removed with heat. There’s a leech farm in Wales, UK and they farm them for medical use.
Very easy to use at home. And extremely effective. Also helps relieve localised Ischemia which results in a build up of metabolic waste, so it’s not just blood they’re sucking out.
Edit: localised metabolic waste includes: Lactate, adenosine, ammonia (NH₃), hypoxanthine, xanthine, bradykinin, prostaglandins, cytokines (e.g. TNF-α, IL-1β, IL-6), and ATP breakdown products (ADP and AMP).
If you’re suffering from the effects of restricted surface blood flow, getting sucked off by a bunch of leeches will give you much needed relief.
Edit 2: the leaches in this video are not medical grade leaches. Those are a sub-species raised indoors in sterile conditions, and can be purchased online.

What's extra cool is these benefits have been known for centuries if not millennia, as well as other dubious "benefits" attributed to leeches through the ages.
This association is so deep the word "leech" in English likely shares an origin with Old English læce for physician or healer. What we would now call the practice of medicine was for a time called leechcraft.
There's an old medical text called Bald's Leechbook which is a collection of cures and poultices from over 1000 years ago (notably, few or none of them are about the actual animal we're talking about in this thread; "leech" just means "healing" in the book title); one of the recipes for styes was even tried out in modern times and found to be moderately effective against MRSA.

Not a lot to tell, really. My best buddy's sister was a casting director for a while and had the inside track for a lot of stuff that was being filmed in the area. She'd tell us they needed extras at such and such and to get over there. I think half of the town of Eugene, Or. showed up for the pie eating scene. Good fun. I sometimes watch Stand By Me just to see old faces from back then.
I also like to brag about how James and Josh Brolin were in MY movie. It was a crappy, made for TV movie about the evils of steroids called The Finish Line. I think I was credited as runner #7, or something. I was literally the only person who ran track for real. Josh was cool AF. James was very full of himself since he was a starring character in Dynasty.
Hope you're impressed with my acting credentials. Lol

Urk. Yeah - not only do you have to watch where you're putting your feet, but you have to worry about what's at head height and above as well. The leech found between the butt cheeks was the one I remember most. Not my butt cheeks, I hasten to add. Some poor soul who had to drop his linen in the middle of a rainforest and have another hasher remove it for him. The story was retold with great delight at the beach BBQ after. A few beers in and the leech guy was laughing about it as well.

Not in and off themselves, unless you are already severely anemic and have hundreds of them on you.

Leeches are adapted to feed on larger animals with steady blood flow, and they recognize suitable hosts through heat, movement, and chemicals. Another leech is a tiny, risky meal that can fight back, so evolution favored finding bigger hosts instead.

Couldn't find the info so leaving it here for anyone else,
Leeches are farmed primarily for medical treatments, scientific research, and fishing bait
Leeches are used in reconstructive surgery to drain pooling blood in reattached body parts and promote better circulation due to the anticoagulants in the saliva
This can also help reduce blood clotting and restore blood flow to tissue that's dying
It can also be packaged with medicine that can cause blood clots to prevent them
Maybe countries use them as regulated living medical tools to be used on patients directly
They also contribute to medical research for the same issues and developing better artificial medicine like blood thinners
Some places apparently use them in anti aging creams or lotion as well
I feel like fishing is probably self explanatory. They are used as bait
