Two common wild plants contain extracts that inhibit the ability of the SARS-CoV-2 virus that causes COVID-19 to infect living cells.
This was established by a study conducted by scientists from Emory University (USA), during which more than 1.8 thousand known extracts and 18 compounds were analyzed, Phys.org reports.
Laboratory studies have shown that the penetration of the SARS-CoV-2 virus into human cells can block extracts from:
- high centaury flowers (Solidago altissima);
- rhizomes of the bracken fern (Pteridium aquilinum).
Both plant species originate from North America and are known for their traditional medicinal use by Native Americans.
However, scientists note that the relevant active compounds are present in plants only in meager amounts, so it would be ineffective and potentially dangerous for humans to try to treat them. In addition, bracken fern is also toxic.
This is a very early stage in the process, but we are working to identify, isolate and amplify molecules from extracts that have shown activity against the virus, the scientists say. “Once we have isolated the active ingredients, we plan to conduct further testing for their safety and long-term potential as a treatment for COVID-19.
