Quercetin shows promise for bronchitis
Integrating serum pharmacochemistry, network pharmacology and untargeted metabolomics strategies to reveal the material basis and mechanism of action of Feining keli in the treatment of chronic bronchitis.
Quercetin effects not isolated
We aimed to gather insights into how quercetin, a component of the herbal preparation Feining Keli (FNKL), may influence chronic bronchitis (CB) treatment. In our study, a rat model of CB was created using a combination of nasal drops of lipopolysaccharide (LPS) and smoking exposure. This model allowed us to evaluate the effectiveness of FNKL in a controlled environment, assessing behavioral changes, body mass, and lung health through various examinations.
Our findings indicated that FNKL has positive effects on CB, showing a potential benefit in alleviating symptoms. One crucial element we identified was quercetin-3-galactoside, which appears to play a significant role in FNKL's effectiveness. We discovered that quercetin might help by reducing inflammation and oxidative stress while regulating metabolic activity associated with bronchitis.
However, it’s important to note that while quercetin is active within the FNKL complex, our study does not isolate its effects from other ingredients. This means that while its importance is highlighted, we cannot conclusively determine quercetin’s standalone effectiveness in treating bronchitis.

Improved breathing
WHERE HAVE YOU BEEN ALL MY LIFE? I've suffered from perennial rhinitis and have struggled with bronchitis due to post-nasal drip. After taking Nasonex, I sought an alternative and found this product. After three days, my breathing is now completely unobstructed. This Quercetin formula seems more potent than others I've tried. It’s a wonderful product!

Supports immune system
An important natural antioxidant, quercetin aids the body's immune system. It's my first line of defence against colds, SARS, bronchitis, and similar ailments. It has consistently helped me manage seasonal illnesses more efficiently and effectively.

Prevents bronchitis
Excellent for allergies that progress into bronchitis. My husband's usual struggle has been mitigated by administering several of these pills daily. Grateful to Jarrow for this product.
