Cupping therapy is an alternative medicine technique that involves placing cups on the skin to create suction. The suction can be created by using a flammable substance such as alcohol, herbs, or paper in a cup and setting it on fire, or by using a rubber pump or silicone cups. Cupping therapy is used for many purposes, including to help with pain, inflammation, blood flow, relaxation and well-being, and as a type of deep-tissue massage. Cupping therapy is believed to draw fluid into the area, which can promote healing and reduce pain. It can also increase blood circulation to the area where the cups are placed, relieve muscle tension, and promote cell repair. Cupping therapy is used to complement care for a host of symptoms and conditions, including back pain, neck pain, knee pain, shoulder pain, asthma, migraines, and gastrointestinal disorders. However, there is limited scientific evidence to support the effectiveness of cupping therapy, and more research is needed to understand its health impacts. Cupping therapy may cause temporary bruising, swelling, or soreness, and some people have reported side effects such as feeling lightheaded or dizzy and experiencing flu-like symptoms.
