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.

Effective for cough
8 people found this helpful
After suffering from Covid and being a pulmonary patient, I found quercetin essential. I discovered its benefits online, particularly for bronchopulmonary patients (COPD), and after consulting my doctor, I incorporated it into my treatment. After two months, I noticed a significant decrease in my cough, fewer episodes of obstruction, and nearly no seasonal colds. Friends reported its effectiveness during Covid treatment, stating it leads to a more manageable infection and quicker recovery. I experienced no allergy or digestive issues while taking it and would recommend it, though consulting a doctor first is wise.

Quick recovery noted

I purchased quercetin for my daughters while using another brand for myself. It was suitable for children, especially after they fell ill with acute respiratory infections. Paired with vitamins, it yielded an amazing result; within two days of dealing with coughing, a runny nose, and a high fever, all symptoms disappeared. I highly recommend it for its quick recovery benefits.

Reduces cough effectively

In cases of pneumonia, chronic bronchitis, asthma, allergies, and obstructive pulmonary disease, quercetin encourages faster recovery, reduces seizures, and leads to a quicker disappearance of cough. It significantly enhances bronchial patency and aids in lung tissue restoration, though its effect is primarily felt during the course of treatment. It's a bioavailable product and of good quality.

Stops allergy cough

I've been taking quercetin for over a year, having learned it aids lung protection post-Covid. Surprisingly, it eradicated my year-round allergy cough. I've switched to Life Extension Bio-Quercetin, which is highly absorbable. After monitoring my body’s reaction, I'm pleased with the noticeable benefits and will definitely reorder.
