Manual Lymphatic Drainage

Manual lymphatic drainage (MLD) is a type of massage based on the hypothesis that it will encourage the natural drainage of the lymph, which carries waste products away from the tissues back toward the heart. The lymph system depends on intrinsic contractions of the smooth muscle cells in the walls of lymph vessels (peristalsis) and the movement of skeletal muscles to propel lymph through the vessels to lymph nodes and then to the lymph ducts which return lymph to the cardiovascular system. Manual lymph drainage uses a specific amount of pressure (less than 9 ounces per square inch or about 4 kPa) and rhythmic circular movements to stimulate lymph flow.
