There’s a new antiviral on the block: Quercetin, which inhibits viral infections in its early stages, during cell attachment and fusion. It demonstrates protection against the H1N1 and H3N2 viruses, and both viruses seem incapable of becoming resistant to quercetin. The compound also improves mental performance in athletes after physical stress. Brightly colored fruits and vegetables can help boost quercetin intake, particularly in apples, dark cherries, red grapes, cocoa, leafy greens, and green tea. It can also be taken as a supplement.
- During the H1N1 pandemic that began in 2009, research shows that about a quarter of a million sufferers were hospitalized with the virus.
- A 2016 review notes that the plant pigment, quercitin, is capable of inhibiting viral infections, especially on the attachment phase.
- Research shows that quercitin has efficacy against both A and B group viruses, even though the latter is especially hard to treat with pharmaceutical options.
“Quercetin, a plant pigment found in fruits and vegetables, has been found to boost immunity and interfere with the process of viral replication.”
