Oh the Humanity! Oh the Horror! Feast your eyes on these green monsters as they feast on the flesh and blood of this poor soul! And you’re next!
Hahaha… Alright, in all seriousness, this is pretty fucking cool. Man with a severe foot injury is having leeches placed on the wound. This is a practice where leeches and other types of organisms such as maggots are used to eat away infection and dead tissue around a wound. “Bleeding” was also an ancient method used for cleansing the body of “bad blood”. It was believed to cure numerous ailments including hypertension although it has largely been abandoned by the early 19th century.
Many thanks to @mrspink!
