The cures are found on pubmed.
I could throw together 20 things, found on pubmed, make an antiviral drink, put a big "Cures Covid 19" on the label, and then be arrested by the FDA.

Glyphosate - poison - in our food is fine with the FDA. But if you want to do what you can with the knowledge that is available on pubmed, the FDA will crack down on you.
The FDAs position and the CDCs position is that unless you get extensive testing, you cannot tell people about the health benefits of your food.
Trump goes out there and says "hydroxychloroquine is the cure" and the FDA says "NO". No hidden secret - we watch this happen.
