Resveratrol, a widely available nutritional supplement, inhibits COVID-19 in cell cultures.

This is not surprising as the roots of japanese knotweed, which are a potent source of resveratrol, is one of the traditional medicines most used to treat COVID-19 in China. This blog has been suggesting it as a possible therapy for quite some time. Its profile of activity makes it a natural match for COVID-19. What this means is that its likely safe to use to prevent COVID-19 associated brain injury and coagulopathy.

Here is a link to the preprint article.

-----------------------------------------

Resveratrol has been used successfully to prevent the highly virulent effects of pseudorabies virus in piglets when provided to them in their food..

It penetrates the brain and makes a huge difference in piglet survival.

Allowing them to survive long enough to be eaten. By us.

Now we see that it similarly inhibits the SARS-CoV-2 virus, which causes COVID-19, in booth human and monkey cells.

In a context which included the fact that resveratrol inhibits a great many viruses, IMHO that means that the chance is looking very good that resveratrol - at reasonable doses, may be able to act as pre-exposure prophylaxis, preventative against COVID-19 infection.

There is also evidence it may substantially reduce COVID-19 neuropathy, coagulopathy, strokes and inflammation.

It may be a real life saver. Why isn't investigating this a top national priority?

Might it have something to do with profit?
