Sucking Blood Gruesomely!!

A woman has blood sucked out of her back in this gruesome video - all in the name of medicine. Puncturing her skin with tens of tiny holes, the physician then places a suction cup over the affected area and brings forth the blood. 

The practice is intended to have therapeutic benefits for this unnamed patient in China. 

But it's long since fallen out of use by modern physicians, who understand that bloodloss is not beneficial to humans.
