John, thanks for your comment. I wouldn’t characterize the research on flavonoids as you have — they have not been shown to be “potent” or “broad-spectrum virus blockers” in the human body. The research on them shows that *some* flavonoids exhibit *statistically* significant antiviral activity “in vitro” (that is, in a petri dish). Until more research is done, everything you mention here is purely theoretical. Flavonoids do seem to have great potential, but the lack of successful “in vivo” (inside an organism) studies strongly suggests that much more research needs to be done. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7087220/
