The practice of cupping has been used for thousands of years in many cultures including China, for the treatment of pain and disease. It is done by placing a flame in a glass cup to create a vacuum, before placing the cup on the skin. The suction caused by the vacuum draws up the skin. The cups can either be left in one position, or they can be moved over muscle groups to relieve tension and pain. In some cases, the cups may leave a red mark that will subside after a few days.

Cupping is used to stimulate the flow of blood and lymph in the affected area, and is particularly used to relieve pain. It can also be used for a variety of other conditions such as cold/flu, asthma, wheezing, etc.
