Bentonite clay is a highly adsorbent substance. Unlike absorption, in which fluid permeates or is dissolved by a substance, adsorption is the adhesion of ions, atoms or molecules to a surface. In this case, the surface energy of the bentonite clay is what draws specific toxins (adsorbates) to it as if they were “pulled by a magnetic field”.
The skin’s function is as a pathway rather than a barrier, and is one of the primary organs of the body utilized for detoxification. While submersed in a tub of very warm water mixed with the bentonite clay, the high adsorbency draws bio-accumulated toxins from within the body, which then adhere to the surface of the clay.
