Which substance is specifically recognized as a preferred binding agent for paraquat in the gut?

Fuller's Earth

Fuller's Earth, or Bentonite, is frequently utilized in clinical protocols for paraquat exposure because of its high binding capacity for the herbicide molecules. The primary clinical objective in the acute phase of poisoning is to prevent the absorption of the toxin from the gastrointestinal tract into the systemic circulation. By administering a large quantity of a potent adsorbent like Fuller's Earth, the chemical structure of the poison can be physically trapped within the gut, thereby preventing its transit through the intestinal wall and into the bloodstream. While activated charcoal is also an adsorbent used in many poisoning scenarios, Fuller's Earth is often prioritized in paraquat cases specifically due to its superior efficacy in binding this particular herbicide.
