Here's the situation. If you want to detox you have to put either the feet or the hands in the footbath. They have the greatest number of pores through which toxins can be eliminated. If you are looking for an electrical treatment for heartworms for instance, consider rife, zapping, and the Beck device and others. Putting your feet in the water detoxes all organs and systems. There is no need to put any other body part in the water because the detox happens through the feet and/or hands.
