This tool is used by eastern medical doctors, acupuncturists and acupressure practitioners to maximise treatment effectiveness by releasing trigger points and disrupting tissue adhesions (adhesions are fibrous bands, or thin sheets of tissue, that grow as a result of trauma to the body). To activate acupressure points place the point or ball of the pen over the desired point and apply firm pressure for 3 seconds while breathing in, then release pressure as you exhale. Gua Sha Pen therapy has been practiced for thousands of years. It is an effective physical therapy from Traditional Chinese Medicine. By exerting force on specific body parts or points, the gua sha practitioner stimulates subcutaneous peripheral nerves, this stimulates circulation of both blood and lymph, and speeds up metabolism.
