What is activated charcoal?
Common charcoal is made from wood, coconut shell, peat, coal, or petroleum. "Activated charcoal" is a processed form of common charcoal that contains pores that can trap other chemicals and prevent them from being absorbed by the body.
Activated charcoal is used to treat certain types of chemical poisonings.
Activated charcoal has also been used in alternative medicine as an aid in treating gas and indigestion.

Activated charcoal is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs.
