Bull shit, it is used by my sister for arthritis, she is in the old person group.
It is known to stop viruses because it an antiviral as Malaria is a virus caused by mosquitoes. Actually it knows over fifty years not twenty-something years and has been tested and passed long time ago. Very few have problems and these problems can be stopped.

Quit putting out shit that can cause problems. The biggest worry people should have is them pushing a vaccine before the tests are done. It has been in development waiting for this very outbreak! No, we are not going to take a deadly vaccine.
