Fantastic. Abosolutely Supreme Quercetin
I've suffered constant misery all of my 70 + years due to allergies to pollen. I recently developed Mast Cell Activation Syndrome. I used the best graded quercetin available during the pandemic, "Now Foods Quercetin + Bromelain" with mixed results. This works with the use of medicinal grade antihistamines..

I use this to block histamine since my body produces too much and it works great. Saves me money ordering vs getting at the local store

Drains your sinus cavities, all four of them. ENT doc was ready to do surgery on my daughter because she was so blocked and had chronic sinus infections. He explained that he does the surgery routinely, that it carries risk of brain damage and has to be repeated again and again. I went to my Sprouts grocery, to their supplement section and asked one of their knowledgeable clerks what use and she told me that her naturopath told her to use Quercetin for just this purpose! It is a natural flavaniod known for it’s anti-inflammatory properties. The theraputic dose (per doc’s instructions) is (2) 500 mg capsules, three times daily for ten days. 8 have my daughter do a cap a day for maintenance. I googled for reviews of this product before giving to my daughter and was Astounded at how many people rely on this! But dont expect your MD to tell you about it. Please give it a try before you go under the knife! It can start draining in as little as 24-48 hours.
