How does clay absorb and adsorb other substances?
The reason for this is that the clay’s minerals are negatively charged while toxins tend to be positively charged; hence the clay’s attraction works like a magnet drawing metal shavings. But it is even more involved than that. Once hydrated (combined with water), Bentonite has an enormous surface area. Bentonite is made of a great number of tiny platelets, with negative electrical charges on their flat surfaces and positive charges on their edges. When bentonite absorbs water and swells, it is stretched open like a highly porous sponge; the toxins are drawn into these spaces by electrical attraction and bound fast.” Dr. Bernard Jensen,”Guide to Diet and Detoxification”. According to the Canadian Journal of Microbiology (31 [1985], 50-53), clay can absorb pathogenic viruses, aflatoxin (a mold), and pesticides and herbicides. Ingested clay is eventually eliminated from the body with the toxins bound to its multiple surfaces. Bentonite, a medicinal powdered clay which is also known as mon
