Quercetin reduces sinus inflammation
This study explored how quercetin may help reduce inflammation associated with sinusitis using a rat model. We observed that introducing lipopolysaccharides (LPS) caused significant inflammation in nasal and sinus areas, as well as in the lungs and brain.
When we administered quercetin after the LPS treatment, it notably decreased inflammatory markers like TNF-α and IL-6. The results indicated reduced inflammation in nasal and lung tissues, showcasing quercetin's potential benefits. However, while there were encouraging findings, its effects on brain inflammation were more limited.

Quercetin enhances mucus transport
We explored how quercetin might help sinusitis by boosting chloride secretion and improving ciliary beat frequency in cultured sinonasal cells. In our analysis, this compound showed notable ability to enhance these functions, suggesting it could promote better mucus clearance from the sinuses.
The study involved primary cultures of human and murine sinonasal epithelial cells and demonstrated quercetin's effectiveness in increasing chloride transport. This implies potential therapeutic benefits for individuals suffering from chronic rhinosinusitis.

We explored how quercetin affects sinusitis by examining its impact on human mast cells. Specifically, we focused on the expression of inflammatory cytokines after stimulating the cells.
Quercetin showed promise by reducing the gene expression and production of key inflammatory signals like TNF-alpha and IL-6. It did this by dampening the activation of NF-kappaB and p38 MAPK pathways, both crucial for inflammation.
This suggests that quercetin may be beneficial for managing conditions like sinusitis linked to mast cell activity.

Skin and allergy relief

Quercetin and bromelain are potent natural ingredients that help alleviate allergic and inflammatory disorders, including sinusitis. They relieve asthma symptoms, promote phlegm elimination, and reduce inflammation in cartilage and joints. As someone with arthritis and allergies, Quercetin has been a lifesaver for me, and I take it regularly. I highly recommend it!

Improved nasal congestion

I started taking one tablet twice daily for my chronic sinusitis. After a month, my headaches from rhinitis faded, and I no longer wake up with a clogged nose. When my rhinitis was severe, I took two tablets twice a day, and I felt progressively better. I intend to continue this.

Moderate sinusitis relief

I took this review from the 120-capsule bottle. I initially experienced headaches but have since adjusted. With sinusitis, my symptoms improved by about 30–40% after taking the supplement. I recommend starting with one tablet a day for a week to adapt, then increasing the dosage as needed.

Anti-allergy effect
4 people found this helpful
I have been taking quercetin for 2.5 years after being diagnosed with AIDS, as prescribed by my doctor. It also has the added benefit of reducing allergies. I took it from July to September to combat ambrosia reactions, and it helped tremendously. Additionally, it contains bromelain, which aids in the fight against chronic sinusitis. I really appreciate the quality of this brand. The capsules are small, with a neutral taste, making it an essential dietary supplement for me.
