Baked Akadama is a version of Japanese red clay that has been heated to higher temperatures than the other two types. Bentonite application also influenced the prices that farmers received for their crops. Production costs are higher, but due to higher production and the quality of the food, clay farmers could afford to invest and grow more and better food, compared to nonclay-using farmers. [40] [41] Bentonite slurry walls in modern construction [ edit ] Digestion. Some animal studies show bentonite might boost good bacteria in the gut. This may help with taking in nutrients. In humans, bentonite is sometimes used to treat occasional or ongoing diarrhea. One study showed bentonite helped with constipation from irritable bowel syndrome ( IBS). More research is needed. Soothes the skin: Hayag lauds its anti-inflammatory properties, saying that it "has been known for many years to help soothe inflamed skin in eczema and psoriasis."a b c Sutherland, Wayne M.

Soaks up oil: Because of those tiny particles, it soaks up all the bad stuff on your skin like a sponge. According to King, volcanic ash "works like clay, to soak up sebum, making it especially helpful for those with oily, acne-prone skin."

The main uses of bentonite are in drilling mud and as a binder, purifier, absorbent, and carrier for fertilizers or pesticides. As of around 1990, almost half of the US production of bentonite was used as drilling mud. Minor uses include filler, sealant, and catalyst in petroleum refining. Calcium bentonite is sometimes marketed as fuller's earth, whose uses overlap with those of other forms of bentonite. [11] [23] Drilling mud [ edit ] Khan MM, et al. (2022). Assessment of antimicrobial potential of Plagiochasma rupestre coupled with healing clay bentonite and AGNPS. FDA: “FDA warns consumers about health risks with Alikay Naturals -- Bentonite Me Baby -- Bentonite Clay,” “FDA Warns Consumers Not to Use ‘Best Bentonite Clay.’” Bentonite has a high cation exchange capacity. That means clay, which has a negative charge, can attract positively charged ions. Those are minerals like magnesium, sodium, and potassium. Bentonite also has aluminum and silica.Saleth, R.M., Inocencio, A., Noble, A.D., and Ruaysoongnern, S. 2009.
