Baldr Look, I don't want to come off as anti-leech here, but I'm still waiting to see how they handle a staph infection. We've got videos of leeches, and videos of flesh-eating bacteria, but the two have never thrown down to determine who the ultimate human parasite is.
My money is on the leeches. If they can suck human blood, they can drain an infected cyst in no time at all. They're nature's sucking machines, let them suck, it's what they do.
