Cupping in TCM
Cupping is a method of applying acupressure by creating a vacuum next to the patient's skin. In traditional Chinese medicine (TCM) it involves placing glass, plastic, or bamboo cups on the skin with a vacuum.
The therapy is used to relieve what is called "stagnation" in TCM terms, and is used in the treatment of respiratory diseases such as the common cold, pneumonia, and bronchitis. Cupping is also used to treat back, neck, shoulder, and other musculoskeletal pain.
It may have some marks for severals days to a week after the cupping, but it is a safe modilty to move the stagnation of Qi/ Blood and promote the energy flow.
