An ancient tradition in many cultures, cupping involves the application of glass or plastic cups with suction to the body. The process is not long (15 minutes), but the results are quite effective. The suction draws blood into the muscle; this nourishes the area and also releases any adhesions in the fascia and muscle. The end result is similar to a deep massage. The downside are round “hickies” that dissipate in a few days. These are a painless aftereffect.
