In an unexpected yet ingenious development, scientists have discovered that gum made from beans—yes, actual beans—could help combat some of the world’s most common and dangerous viruses.
Researchers from the University of Pennsylvania’s School of Dental Medicine, in collaboration with Finnish scientists, have created a plant-based antiviral chewing gum that can reduce viral presence in the mouth by over 95%. The key ingredient? A natural protein called FRIL, derived from lablab beans, traps and neutralizes viruses before they can spread.
Led by Professor Henry Daniell, the team tested the gum on four major viruses: herpes simplex virus types 1 and 2 (HSV-1 and HSV-2), as well as two strains of influenza A (H1N1 and H3N2). The outcome was remarkable—just one piece of gum containing 40 milligrams of FRIL reduced the viral load in the mouth to nearly undetectable levels.
Yes, you read that right: a stick of gum could become a powerful tool in stopping virus transmission.
The findings, recently published in Molecular Therapy, build on earlier research showing similar effects against COVID-19. The gum has also met U.S. FDA safety guidelines, positioning it as a promising candidate for human trials.
But the applications don’t stop at gum. The same bean-based protein is now being tested as a possible treatment for bird flu, which has devastated poultry farms across North America—impacting more than 54 million birds in just three months. Daniell’s team is exploring the idea of adding the protein to bird feed, potentially protecting both animals and humans from infection.
What makes this breakthrough especially timely is its simplicity. Traditional vaccines and treatments take months—or even years—to develop. In contrast, this gum is scalable, cost-effective, and safe, offering a potential first line of defense in future outbreaks.
So yes, fighting pandemics might come down to something as simple as chewing gum.
While more studies and real-world clinical trials are still needed, the potential is undeniable. In a world worn down by COVID-19, herpes, influenza, and H5N1, this humble bean-based innovation might just be the unexpected hero science was chewing on all along.
Fresh breath, strong defense—chew wisely.
