We uncovered how quercetin, alongside a specialized compound called PSFL2915, affects chronic cough by interacting with a specific part of a receptor known as P2X3.
Our tests showed that quercetin could effectively reduce coughing in male mice and guinea pigs without causing taste disturbances—a drawback seen with other similar medications.
This suggests that quercetin could be a promising alternative to existing treatments for chronic cough, offering a potential new avenue for relief.

We explored whether quercetin, a compound derived from medicinal plants, affects coughing by relaxing airway smooth muscles. By conducting experiments with guinea pig tracheal rings, we found that quercetin effectively reduced contractions triggered by various stimulants. It worked by blocking specific calcium channels that are critical for muscle contraction.
However, the study mainly focused on the physiological mechanisms rather than directly measuring cough relief in humans. While quercetin shows promising properties in muscle relaxation, more research is needed to evaluate its direct impact on cough in clinical settings.

Quick recovery

It works! Yesterday, I felt awful, wheezing at night and coughing up green mucus. I took my last two capsules along with two NACs and one Zinc. Within three hours, I felt much better. I'm delighted; I was not looking forward to being off work again! This is my second bottle, and I will keep taking it.

It helped a lot! Many are already aware of the benefits of Quercetin. I purchased it for my mother, who has suffered from allergic asthma for years. After beginning Quercetin, she stopped using her cough spray altogether, and both the cough and her seizures ceased.

Great cough relief
Quercetin has been my go-to as I contend with poor bronchial health. I suffered from persistent coughing and rhinitis, yet after consistently taking a set of quercetin, propolis, and Epicor, I experienced considerable relief. I highly recommend it to anyone struggling with similar issues.

Effective for cough
1 people found this helpful
Effective but requires long-term use. At 70 years old, I had a persistent mild cough after catching a cold. Despite multiple courses of antibiotics improving my condition temporarily, the cough returned after meals. I started taking quercetin, one pill daily, and after nine months, I noticed my cough had disappeared. Occasionally, it returns post-cold, but it is less severe once the cold resolves. I believe in long-term use of this remedy for sustained improvement.
