A man with some kind of head wound was subjected to the practice of “cupping”. Cupping is an old practice in which a cup is placed over a wound to create suction. In this case, the purpose seems to be to extract blood. Incisions have been made in his head and the cup placed over it. After a time, a big glob of semi coagulated blood fills the cup like some cranberry sauce. Perhaps the man was bit by a snake or maybe just trying to remove some other kind of infection. No info came with the video so it’s open to speculation. Pretty neat.
