Either way, good article with timely content, upvoted!
Call me when he's finished a double blind trial with a significant number and cross section of participants. Until then, it's all just people clutching at straws (just like yesterday's smoking study or last week's Chloroquine study).
Many businesses sell a mix of proven products and snake oil (homeopathic meds mixed into real ones, for example). That doesn't make them charlatans, although the sellers of those homeopathic remedies might be.
Inventing or promoting an ineffective product with the knowledge that it's ineffective is what makes someone a charlatan. The people selling these ineffective Covid-19 remedies are only charlatans because they're selling bad remedies. If they weren't, the label wouldn't fit.
I think you may have accidentally put the cart before the horse here.
