Researchers tested extracts from traditional Tibetan medicinal plants, mushrooms, and lichens to see if they could fight influenza virus. They found that seven out of nine extracts could reduce influenza virus infection in laboratory cells, with a mushroom extract called Armillaria luteo-virens showing particularly strong antiviral effects. These results suggest that traditional medicinal materials from the Qinghai–Tibetan plateau could be valuable sources for developing new flu treatments that might work better against drug-resistant flu strains.
