Bentonite clay is a natural mineral clay formed from volcanic ash, long used in folk medicine traditions for skin care and digestive support. Research suggests that its unique structure allows it to bind to certain toxins and impurities, which may explain its traditional use as a topical poultice for insect bites and skin irritations. Studies indicate that when applied as a mask, bentonite clay may help absorb excess oil and support overall skin health, though more rigorous clinical trials are needed. Some preliminary research has also explored its potential role in digestive wellness, as it may help bind unwanted substances in the gut, but evidence in this area remains limited and ongoing. As with any folk remedy, consulting a healthcare provider before internal use is a sensible step.
