Activated carbon is a product made from coal by treating it with heat and steam or chemicals. This process creates many micropores and increases its surface area, making it highly absorbent.
In medicine, activated carbon is often used as an absorbent to absorb toxins and other harmful substances in the gastrointestinal tract. It can be used in cases of poisoning or overdose with drugs or chemicals, as well as to reduce gas formation and reduce unpleasant odor from the stomach.
Activated charcoal can help bind toxins and prevent them from being absorbed into the bloodstream, which helps them pass out of the body through stool. It is often taken as a tablet or powder mixed with liquid.
