it is an external detoxification method, which removes toxins through your feet. the body detoxifies while you are comfortably seated with your feet placed in a container of warm water. this is a very efficient way to remove toxic accumulations regardless of where they are located in the body. the ion-cleanse process generates a stream of positive and negative ions (charged atoms), which attract and attach themselves to oppositely charged toxic particles and draws them out of the body through the skin. each session takes about 30 minutes. the array goes into the water with the hands, feet, or body, and the power supply delivers a small amount of direct current into the array, which causes the metals within it, in combination with water, and salt, to generate positively and negatively charged ions.
