Cupping therapy gone too far.

From reading the link it is done that way to draw out blood:
Alternatively, mild suction is created using a cup and a pump (or heat suction) on the selected area and left for about three minutes. The cup is then removed and small superficial skin incisions are made using a cupping scalpel. A second suction is used to carefully draw out a small quantity of blood. The procedure was piloted and developed by Ullah et al 2005 and has been endorsed by the British Cupping Society[1] which aims to promote, protect and develop professional standards in cupping therapy.
Looks like a BS way to get healthy.
