Cupping is a rather new technique compared with more ancient practices in TCM.
When muscles are tight or in pain, there is stagnation in the meridians, whether that be blood or Qi stagnation will depend on the type of pain.
This process uses small glass cups or suction devices that are placed on the skin to disperse and break up stagnation and congestion by moving congested blood and Qi, bringing new blood flow to the area.
Although people have the perception it’s painful, it is an extremely relaxing treatment that you walk away feeling great from.
