Quercetin shows promise for bronchitis
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.

We investigated how quercetin, a powerful antioxidant and anti-inflammatory, affects mice exposed to agents that cause chronic bronchitis and emphysema. After treatment with quercetin, these mice showed noticeable improvement in lung function and reduced inflammation.
Moreover, quercetin decreased harmful substances associated with oxidative stress and the activity of certain destructive proteins linked to lung damage. While promising in this animal model, further research is needed to clarify its potential in human cases of bronchitis and COPD.

We began our exploration by analyzing how the Tonifying Spleen-Lung Recipe (TSLR) can help treat chronic bronchitis, a common respiratory issue often marked by persistent coughing and mucus. By including 137 elderly patients undergoing TSLR and comparing them with a control group of 67, we looked into the effective components and mechanisms behind TSLR's impact.
Our findings indicated that TSLR offers significant therapeutic benefits, likely by targeting inflammation through specific protein pathways. This research contributes to understanding how herbal treatments can support respiratory health.

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!

We examined the effectiveness of a combination of Gleditsiae sinensis fructus Pills and Jujubae fructus in treating chronic bronchitis. Our research involved predicting potential targets using network pharmacology and verifying through various experimental methods, including the examination of inflammatory factors in a model of chronic bronchitis.
The findings showed that this combination significantly alleviates symptoms. We found that key ingredients, particularly quercetin, play an essential role in reducing inflammation and modulating signaling pathways related to the condition.

We investigated the effects of Elaeagnus pungens leaves and its key components, quercetin and kaempferol, on conditions like asthma and bronchitis. Through various pharmacological tests, we found that these compounds significantly reduced inflammation and coughing in mice, hinting at their potential benefits for treating bronchitis.
Our analysis also revealed that the levels of quercetin and other active ingredients differ across species and plant parts. Notably, the leaves of E. pungens proved to be particularly effective compared to other parts, offering hope for future treatments.
