Quercetin is a zinc ionophore - it helps zinc ions change their charge so that cells can absorb them more easily. The zinc stops the replication of many viruses, including the Wu Flu.
FYI, this is part of the reason that Hydroxychloroquine works. Quercetin isn’t as efficient of an ionophore, so instead of taking 200 mg twice a day like HCQ, you need about 1,000 - 1,200 mg/day of Quercetin - according to the article I read about this a few weeks ago.
Thank you. Good stuff
