Activated charcoal is the highly adsorbent carbon left after burning coconut husks. This carbon residue is treated to remove impurities and to increase the adsorption quality of the charcoal. Charcoal is used to bind toxins within the digestive tract and remove them safely from the body, as the charcoal itself is not digested. Ideal to feed to horses who have had a sudden diet change, or those that have been gorging on grass/cereals.
