Super for clearing sinuses

Posted by iHerb Customer on December 3 2017 | Verified Purchase

Our go-to product for opening stuffed sinuses and for stopping a runny nose. My husband has seasonal allergies and takes this during those times too, instead of drugs. It kicks in subtly and wears off in about 6 hours. It's not habit-forming and doesn't cause drowsiness. Usually just one capsule does the job.

Thanks for your feedback!

Necessary for allergies

Really useful for allergies

Posted by iHerb Customer on September 10 2017 | Verified Purchase

I use this product to treat my seasonal allergies. I have tried many quercetin products but this has been the best for me. It helps me with runny nose and watery eyes.
