Effective for asthma
5 people found this helpful
It helped a lot! Many are familiar with the benefits of quercetin. I purchased it for my mother, who had suffered from allergic asthma for years. After starting quercetin, she stopped using her cough spray entirely, and her cough and seizures have vanished.

Significant relief achieved
Quercetin is fantastic! I take quercetin, propolis, and Epicor regularly for my poor bronchial health. I previously suffered from severe coughing and rhinitis, but after consistently using this three-piece set, I’ve felt substantial relief. I highly recommend it for anyone with similar issues.

Cough improvement noted
1 people found this helpful
Effective but requires long-term use. At 70 years old, I’ve had a persistent mild cough since catching a cold. The doctor prescribed antibiotics, and although I improved temporarily, the cough returned after eating. Others suggested quercetin, so I tried taking one pill daily. After my son turned 9 months, I noticed my cough had disappeared. Occasionally, it returns after a cold, but it’s generally better once the cold passes. Consistency is key in my experience.

Reduced coughing significantly
My cough hadn’t improved for a while, so I tried onionin and green tea extract. Thankfully, both my coughing and asthma symptoms were significantly reduced.
