Cupping is an ancient technique that was initially used in ancient China to treat common colds.  It involves creating a vacuum in glass or plastic cups, either by using a flame to burn out the oxygen inside or using a suction pump.  The vacuum created may stimulate blood flow to the area.

Sliding cups over a larger body area is another technique which may be applied to larger body areas like the upper back.  This is also a technique used in cellulite reduction.
