“Quercetin actually works for me with no side effects, one product of many that I have tried. I cannot take any script meds for my non allergic rhinitis I have a lot of swelling, headaches and irritation in my nose/head along with much drainage and this does help reduce my symptoms. My system is so sensitive I seem to inevitably suffer side effects from most medicine, but this spray is different, I suffer no negative effects. I have used 6 or 12 sprays twice a day, as well as trying 6 sprays 4 times a day as my days always seem different and keep me guessing how bad I will feel. If you stick with this product and give it a try you might be surprised, I was and happy to find something to reduce my issues.”
– Barb D
““I have terrible symptoms every spring. My symptoms include itchy, red, eyes, stuffy nose and scratchy throat. It is also difficult to sleep at night due to nasal congestion and coughing resulting from post-nasal drip. The first night I used Quercetin, I was able to sleep because I could breathe and had no cough! In the morning, my eyes were clear and not itchy. I could not believe a natural product could be this effective, this quickly, and thankfully with no side-effects!”
– Trina I

“I work with toxic chemicals and have seasonal symptoms which means I have severe sinus congestion, post-nasal drip, sore throat, cough, irritated eyes and headache most of the time. It is difficult to breathe and have a chronic cough which disturbs those around me and my sleep. Saline washes and medications do not help for very long and I do not like the side-effects. I was so excited when I used this product! Within minutes, I had noticeable improvement in my symptoms. I could not believe that I could breathe, my eyes did not burn, my throat did not hurt, and I did not cough for hours! I love this product and recommend folks with these types of symptoms to give it a try. I am so glad I did.”
