Cupping is most commonly used to treat coughs, asthma, and symptoms of the common cold. It can also be used for muscle aches and pain, especially back pain. Sliding cupping, in particular, leaves the muscles of the back relaxed and opens up movement and motility. Most people find cupping to be a wonderfully relaxing, comfortable, and effective treatment. Like massage, cupping can also be used to relieve stress, tension, and lower blood pressure.
