Green tea, olive oil and red wine all contain compounds that can fight Covid-19.
The compounds stop the SARS-CoV-2 virus from spreading—and now researchers want to replicate them in new drugs to fight Covid.
In tests on around 500 natural substances, researchers from the University of Hamburg discovered that the compounds in green tea, olive oil and red wine were especially effective against the virus; they stopped it spreading and from blocking an immune response.
The compounds, which reduced the virus’s virulence by up to 70 percent, are safe, and naturally occur in the drinks, the researchers say.
