Gua sha is a technique used in traditional East Asian medicine. It is often used to treat muscle pain and tension, but there has been limited research into how well it works. We find out more about whether this technique is effective, and if it has any side effects.
What is gua sha?
It is the practice of using a tool to apply pressure and scrape the skin to relieve pain and tension. This action causes light bruising, which often appears as purple or red spots known as petechiae or sha.
The name gua sha — pronounced gwahshah — comes from the Chinese word for scraping. It may also be called skin scraping, spooning, or coining.
According to traditional Chinese medicine, qi or chi is energy that flows through the body. Many people believe that a person’s qi must be balanced and flowing freely to ensure their health and wellbeing.
People also believe that qi can become blocked, causing pain or tension in the muscles and joints. Gua sha aims to move this blocked energy to relieve aches or stiffness.
Traditional East Asian medicine also views blood stasis or stagnation as a cause of pain and illness. Another aim of this technique is to move pooled or stagnated blood to relieve symptoms.
Some physiotherapists use a version of the technique known as instrument assisted soft tissue mobilization (IASTM). Using a tool instead of the hands during a massage allows a physiotherapist to apply more pressure.
Uses
Gua sha is most often used to relieve muscle and joint pain. Conditions of the muscles and bones are known as musculoskeletal disorders. Some examples include back pain, tendon strain, and carpal tunnel syndrome.
Practitioners claim that it can also benefit the immune system and reduce inflammation. Sometimes, it is used to treat a cold, fever, or problems with the lungs.
