Patient Education

Activated Charcoal


What is it? Activated charcoal has pores that can trap chemicals. It is typically taken by mouth as a treatment for some swallowed poisons. There is little evidence for other uses.

Charcoal is made from peat, coal, wood, coconut shell, or petroleum. Activated charcoal is made by heating charcoal in the presence of a gas. This process causes the charcoal to develop lots of internal spaces or pores. These pores help activated charcoal trap chemicals.

Activated charcoal is commonly used to treat poisoning. It is also used for high cholesterol, hangovers, and upset stomach, but there is no strong scientific evidence to support most of these uses.
