Cupping is the term applied to a technique that uses small glass cups, bamboo jars, or modern version cups as suction devices that are placed on the skin.
The suction and negative pressure provided by cupping can loosen muscles, encourage blood flow, and sedate the nervous system (which makes it an excellent treatment for high blood pressure). Cupping is used to relieve back and neck pains, stiff muscles, anxiety, fatigue, migraines, rheumatism, and even cellulite. It is also valuable for the lungs and can clear congestion from a common cold or help to control a person's asthma. In fact, respiratory conditions are one of the most common maladies that cupping is used to relieve.
Cupping is safe, especially when performed by trained health professionals. But after the cupping therapy, bruises or mild discomfort can be experienced for several days.
