Most varieties of Airborne, the popular "herbal" remedy used by professionals who travel frequently by air to prevent colds, contain sucralose (Splenda).
Three of the four products in the Airborne line -- Airborne Original, Airborne Lemon-Lime, and Airborne Jr. -- contain sucralose. The fourth uses sugar.
Airborne claims its products are a combination of seven herbs, which are put through a patented extraction process and then combined with amino acids, anti-oxidants and electrolytes. It is sold as a dietary supplement rather than a drug, so its claims and ingredients have not been evaluated by any health agency.
