When Victoria Knight-McDowell taught second grade at Spreckels Elementary School near Carmel, California, she often brought home more than papers to grade.

That inspired her to create a drug-free formula that would give her immune system a fighting chance. After consulting with nutrition experts and herbalists, she experimented with different formulations and delivery methods before creating the blend that would eventually become Airborne.

From its homegrown roots, Airborne has become the leading herbal supplement in retail drugstores, supermarkets and mass merchant retailers nationwide.

Victoria's best-selling product remains true to her philosophy and to its humble origins. Airborne is an herbal formula made by a teacher who refused to have her immune system pushed around.

"When we started producing Airborne commercially, I thought it could become a successful product for people who want a natural way to support their immune system. But I had no idea it would take off the way it has."
