Although there had had countless memes in recent days about Pres. Trump's public 'brainstorm' of ideas concerning how to battle Covid-19 infections. There is a scientific paper about a resultant reduction of Influenza-A lung titers using a treatment combination of red ginseng and xylitol (sugar alcohol). So...maybe start buying up Amazon's supply of sugar-free gummy bears and Korean red ginseng tea! Don't have too many gummies though (if you don't know why I said this read the Amazon product reviews)!
