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.

Saved my asthma
Quercetin and bromelain are potent natural ingredients that help manage allergic and inflammatory disorders like bronchitis. They alleviate asthma symptoms and assist in phlegm elimination. With arthritis, Raynaud's syndrome, and various allergies, Quercetin has been a lifesaver for me, and I take it regularly. Highly recommended!

Effective for bronchitis
An excellent remedy! Three months after purchasing, I've evaluated this medication. It helped with my ragweed allergy, and my son, who has chronic obstructive bronchitis, has benefited greatly. It's a good expectorant. We now also use it for immunity in colds, alongside vitamins C and D.

Quick bronchitis recovery
After catching the flu that turned into bronchitis, I discovered Quercetin. Just two capsules daily with Vitamin C cleared my lungs in two days. My brother's bronchitis also improved after a week, and my 87-year-old mother recovered quickly with the same dose. It's best taken with food to avoid heartburn.

Ragweed allergy relief
This product has been a lifesaver during ragweed season. For over 10 years, I've struggled with allergies, which turned into obstructive bronchitis. Since I started taking two tablets daily and increased to six during peak pollen times, I’ve experienced no allergy symptoms this year!

I struggled with severe bronchitis, and after just two days of taking this product, I noticed significant improvement and was finally able to sleep at night. I also gave it to my mother during her battle with COVID-19, and it provided excellent results.
