Many alternative medicine practitioners appreciate the effectiveness of BC in the process of colon cleansing and detoxification. BC is very useful in eliminating pathogenic viruses, aflatoxins, other toxins, pesticides, and herbicides and even toxic metals such as mercury, aluminum, lead and others. The BC naturally attracts the particles of these toxins and waste via magnetism and its great ability to absorb. In the colon, bentonite acts like a sponge in the sense that it expands when it absorbs water. Since toxins are drawn to the BC, this helps purge and detoxify your body of harmful materials and waste. Food-grade BC is a medicinal powdered clay which is also known as montmorillonite. It is derived from deposits of weathered volcanic ash. A bentonite cleanse is one of the most effective natural intestinal detoxifying agents available and has been recognized as such for centuries by native cultures around the world. The BC absorbs and binds toxins such as heavy metals, free radicals and pesticides that reside in the intestinal tract. Bentonite is also an inert substance. This means it is not absorbed by the body and will essentially pass through without being changed. This allows it to collect the toxins from your body and remove them.
