QUERCETIN UPDATE: I’ve talked about quercetin before, but the Insta-Daughter started taking Quercetin and reports that within a few days her sinuses were vastly improved. This wasn’t the result of my urging, but a recommendation from her ENT doctor.

UPDATE: I should note that she takes it (the linked brand) twice a day and says that makes a difference; I’ve always just taken it once a day. Plus, note lots of similar experiences in the comments.
