A new study led by Emory University has found that two common wild plants can inhibit the activity of the virus causing Covid-19 to infect human cells. Laboratory experiments revealed that extracts from the flowers of tall goldenrod (Solidago altissima) and the rhizomes of the eagle fern (Pteridium aquilinum) efficiently stopped SARS-CoV-2 from entering human cells. Since the active compounds are only present in small quantities in the plants, it would be ineffective – and even potentially dangerous – for people to attempt to treat themselves with them. “It’s very early in the process, but we’re working to identify, isolate...
