Scientists believe that bentonite clay works when absorbing oils and dirt from the skin.
The theory is that bentonite clay absorbs materials, by sticking to their molecules or ions. As the clay leaves the body, it takes the toxin and other molecules with it.
When a person uses it on the skin, bentonite clay may have the power to adsorb oils and bacteria. When they consume the clay, it may absorb toxins and other unwanted substances from the digestive tract.
Bentonite clay contains natural minerals such as calcium, magnesium and iron, which may provide additional benefits.
Bentonite clay is formed from volcanic ash. It gets it’s name from Fort Benton in Wyoming, where it occurs in large deposits. People may also find this clay in other places, where volcanic ash has permeated the ground.
