The process of detoxifying the body by opening the emunctories (organs of elimination; i.e. liver, kidney, lung) and then excreting the toxic accumulations. Unlike “detoxing or metabolic cleansing,” biotherapeutic drainage works extracellularly and intracellularly, restoring optimal cellular function. UNDA numbers actually work not only by removing toxins from outside and inside of cells, but restore enzymatic and biochemical pathways to their optimal functioning.
Essentially, biotherapuetic drainage is a method of medicine that cleanses, purifies, corrects function and optimizes all cells, tissues and organs in the body, including the brain and central nervous system.
