From old times, the human kind has used clays, externally or internally, for maintaining body health or treating some diseases. Meanwhile there are few scientific articles reviewing the beneficial effects of clays on body function. Bentonite clay is one of the available clays in nature, used as traditional habits, and remedies in many cultures.
Scientists believe that bentonite clay works by adsorbing oils and dirt from the skin.
The theory is that bentonite clay adsorbs materials by sticking to their molecules or ions. As the clay leaves the body, it takes the toxin or 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 adsorb toxins or 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 forms from volcanic ash. It gets its name from Fort Benton in Wyoming, where it occurs in large amounts. People can also find this clay in other places where volcanic ash has settled into the ground. Montmorillonite clay, named after Montmorillon in France, is the same type of clay.
The following list looks at the benefits of bentonite clay and what the research says.
1. Removing toxins from the body
Some people ingest bentonite clay with the aim of removing toxins from the body. This may be one of its most well studied benefits.
Various studies suggest that bentonite clay may reduce the effects of toxins.
For example, a study on chicks found that bentonite clay reduced the effects of a toxin called aflatoxin B1, which comes from certain types of mold. Chicks that received a concentrated bentonite clay product had fewer toxic effects than those who did not receive the clay.
Another studyTrusted Source looked at the effects of montmorillonite clay, which is very similar to bentonite clay, on reducing toxins in children in Ghana, West Africa. In the study area, aflatoxins in homemade nutritional supplements are linked with poor growth and related disabilities.
The researchers found that children who received a calcium montmorillonite clay product each day for 2 weeks had fewer signs of aflatoxins in their urine than those who did not receive it.
In a small-scale animal study, rats consumed wastewater that contained cyanide. Researchers gave some of the rats various amounts of bentonite clay or a placebo. Those that received the most clay had the lowest amount of the toxin in their bodies after 3 weeks.
Scientists need to conduct more research before they can confirm that bentonite clay is safe and effective for use in humans.
