Quercetin has been used to ameliorate obesity, Type 2 diabetes, circulatory dysfunction, chronic inflammation and mood disorders.
As noted in one paper, "the most obvious feature of quercetin is its strong antioxidant activity which potentially enables it to quench free radicals from forming resonance-stabilized phenoxyl radicals."
For example, a 2010 animal study found that quercetin inhibits both influenza A and B viruses. Importantly, they also discovered the viruses were unable to develop resistance to quercetin. What's more, when used concomitantly with antiviral drugs (amantadine or oseltamivir), the effect was significantly amplified, while preventing drug-resistance from developing. Quercetin has also been shown to be effective against:
- "Bird flu" (H5N1)
- "Swine flu" (H1N1 and H3N2)
- Herpes simplex virus type 1, polio-virus type 1, parainfluenza virus type 3 and respiratory syncytial virus
- Hepatitis B59 and C
- Dengue
All that to say adding Moringa to your diet this flu season may help.
