A team found evidence that the herb rosemary could be a two-pronged weapon against the SARS-CoV-2 coronavirus that causes COVID-19. The scientists found that the compound, carnosic acid, can block the interaction between the SARS-CoV-2 outer "spike" protein and the receptor protein, ACE2, which the virus uses to gain entry to cells. The team presented evidence carnosic acid has a separate effect inhibiting a powerful inflammatory pathway—a pathway active in severe COVID-19 as well as Alzheimer's. "We think that carnosic acid is worth investigating as a potentially cheap, safe, and effective treatment for COVID-19 and some other inflammation-related disorders," says...
