Lymphatic Drainage: When the body encounters an excessive or inefficient accumulation of fluid it uses little vacuums, called lymph nodes, all over the body to absorb that excess and safely transport it out of the body. The lymph nodes become congested from absorbing too much excess, either because the person’s kidneys are not working correctly, they are continually sick and those toxins are getting stored in the lymph nodes, or their eating habits cause them to retain fluids. Acupuncture points are often selected in proximity to lymph nodes when there is this type of imbalance to increase the activity and circulation of the lymph nodes, assisting them in ridding themselves of old debris so that they can do their job more efficiently.
