    Super for clearing sinuses

    Posted by iHerb Customer on Dec 03, 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!

    Really useful for allergies

    Posted by iHerb Customer on Sep 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.
