You guys are going in circles not getting anywhere. Look its Tollovir - its a 3CL inhibitor just like what Pfizer is doing. So it all natural 3CL inhibitor and the 3CL is the protease. That protease is the first thing the virus makes after the capsid is uncoated. By blocking it the viral replications. Its a nutraceutical which probably means the other stuff in there does the immuno modulating. It worked in hospitalized patients very well since no one died.
