Cupping is done by creating suction in a plastic or glass cup and placing it on muscle and subdermal connective tissues. The suction causes layers of tissue to bubble up into the cup. Cupping can be done both stationary over tight areas or the cups can be manually moved along the length of the back, neck or leg which is termed sliding cupping. A healthy muscle tissue allows muscle fibers to slide and extend over underlying layers but tissue that is damaged or inflamed restricts this movement. The suction action, of the cup, forces these layers to become ‘unstuck’, drawing blood between the layers and allowing for repair and healing of the area.
