How does Kaolin work?
Kaolin acts as a protective coating for the digestive tract to decrease pain associated with radiation-induced damage. Kaolin was formerly used for diarrhea as an ingredient in products such as Kaopectate. But the Food and Drug Administration (FDA) could not find sufficient research to support its use for diarrhea. Kaopectate and similar products no longer contain kaolin.
Are there safety concerns?
Kaolin seems to be safe for most people. It can cause some side effects including constipation, particularly in children and the elderly.
Do not inhale kaolin. It can cause lung problems.
