A black liquid(and sometimes in tablet form) that is used to filter out any poison or chemical harmful to the body.

Most often used in the ER, when someone overdoses on something whether intentional(suicide attempt) or accidental.
Tina wanted to end her life so she OD'd on tylenol, her mother found her 30 minutes later in the bathroom and took her to the hospital where she was given activated charcoal to absorb the all those nasty chemicals she had taken.
