What are some benefits of eating white clay dirt?

Kaolin, or white clay, is a possibly effective form of treatment for soreness and swelling inside the mouth, states WebMD. It consists of kaolinite, a mineral that comes from the Earth's crust.

Although there are claims that kaolin can also treat diarrhea, ulcers and inflammation in the colon, there is insufficient evidence for such uses, WebMD warns. Kaolin may cause constipation for some people, especially children and the elderly. It can cause lung disorders when inhaled.

Kaolin is also used by some people to dry or soften the skin, adds WebMD. It may hinder the absorption of drugs that chelate with aluminum salts, trimethoprim and quinidine, warns Drugs.com.
