Cupping is a technique that uses glass and heat or plastic with a pump to create suction on the skin. This increases circulation, activates the lymphatic system, releases toxins, and opens up meridians (channels where the energy flows). This is a great way to increase localized healing and release muscles, decreasing pain. It is useful for asthma, chest congestion, early stages of cold and flu, muscle pain or tightness, or poor circulation. It can even be used to just relax and unwind from a stressful day.
