In one of seven studies published in the Journal of Allergy and Clinical Immunology, researchers say liquid charcoal, which is often used when people ingest poison to block absorption, can also absorb peanuts.
"After you've eaten the peanut and you have an allergic reaction, you still have peanut in your stomach," explained Dr. Donald Leung, editor of the journal. "And so rather than allow further peanut to be absorbed and have an even more severe reaction ... drinking the charcoal will prevent the further triggering of increased symptoms."
Leung advised that parents of young children with the allergy keep liquid charcoal -- available in pharmacies -- in the home, in case of accidental ingestion.
