Our Story

Many medical breakthroughs are market-driven. When an illness or disease threatens a large segment of the population, doctors, scientists, and chemists work to find a solution. In some cases, though, the problem to be solved hits closer to home. That was the case for Bill Wingfield, the founder of AG Essence and inventor of the unique Ag21 Complex molecule. Bill’s inspiration was a family member, a diabetic, for whom even a common infection could have devastating effects. As a “serial” inventor and experienced chemist possessing numerous patents, Bill was well-versed in the medical benefits of silver when his Ag21 journey began. By binding silver with the naturally-occurring, non-toxic polymer chitosan into a unique complex, he was able to create an advancement in ongoing protection of wounds in a natural non-toxic formulation.

After filing a patent for his unique complex, Bill met a renowned equine veterinarian who needed something for equine health management in the thoroughbred racehorses he treated. Other silver-based products had been used on horses, but the Ag21 Complex formulation proved so successful in equine management that it became the only agent of its kind approved by the Kentucky Horse Racing Commission.

In the Spring of 2016, AG Essence launched the Banda-SiL line of products, with the goal of making the Ag21 Complex available to people everywhere. Banda-Sil’s ability to create a preventive barrier that provides a moist wound environment has made it a revelation in the wound-care industry. As a result, just two years after its launch, Banda-SiL is not only available online, but it appears on the shelves of thousands of brick-and- mortar retailers across the United States.”
