Activated charcoal is a natural adsorbent that is used to increase excretion of toxins and to ameliorate diarrhea. It is readily available in over-the-counter forms and is a relatively inexpensive home remedy. It is also used in hospital settings.
Facts
Activated charcoal is carbon that has been processed to increase its porosity. It functions as an adsorbent; that is, atoms and molecules of certain substances will bind to its surface. Sources of medical-grade activated charcoal include wood and bamboo. It is usually supplied as a fine powder, either in capsules or in suspension.
Treatment for Poisoning
Activated charcoal is used to treat patients who have taken poison by mouth. The charcoal binds the toxins until they can be excreted, preventing them from being absorbed by the gastrointestinal tract. In most cases, vomiting is induced, and then the charcoal is given to bind toxins remaining in the digestive tract.
Treatment for Diarrhea
Activated charcoal slows down gastric motility, so it is useful in reducing the symptoms of diarrhea. It has also been used to reduce flatulence and gastric discomfort. In small doses it is safe for babies and children.
Contraindications
Activated charcoal should not be given in cases of poisoning by cyanide, mineral acids, or alkalis. It should not be given to anyone who is unconscious or semiconscious. Anyone who is hypersensitive to charcoal should not take this remedy.
Interactions and Cautions
Activated charcoal will slow down the absorption of many drugs. In high doses, it will cause constipation. The charcoal will turn stools black. Consult a pediatrician or qualified health practitioner for the appropriate doses for infants and children.
Warnings
Always contact emergency services immediately in cases of suspected poisoning. If diarrhea continues for more than 24 hours, or if infants and children are not taking in fluids or appear listless or lethargic, contact the appropriate practitioner immediately.
