New York, Feb 11: Two common wild plants contain extracts that inhibit the ability of the virus that causes Covid-19 to infect living cells, a US study has discovered.
In laboratory dish tests, extracts from the flowers of tall goldenrod (Solidago altissima) and the rhizomes of the eagle fern (Pteridium aquilinum) each blocked SARS-CoV-2 from entering human cells.
The active compounds are only present in miniscule quantities in the plants.
