Like acupuncture, cupping follows the lines of the meridians. There are five meridian lines on the back, and these are where the cups are usually placed. Using these points, cupping can help to align and relax qi, as well as target more specific maladies. By targeting the meridian channels, cupping strives to ‘open' these channels - the paths through which life energy flows freely throughout the body, through all tissues and organs, thus providing a smoother and more free-flowing qi (life force). Cupping is one of the best deep-tissue therapies available. It is thought to affect tissues up to four inches deep from the external skin. Toxins can be released, blockages can be cleared, and veins and arteries can be refreshed within these four inches of affected materials. Even hands, wrists, legs, and ankles can be ‘cupped,' thus applying the healing to specific organs that correlate with these points.
This treatment is also valuable for the lungs, and can clear congestion from a common cold or help to control a person's asthma. In fact, respiratory conditions are one of the most common maladies that cupping is used to relieve. Three thousand years ago, in the earliest Chinese documentation of cupping, it was recommended for the treatment of pulmonary tuberculosis.
