After all it is tea

Nara Medical University (Kashihara City, Nara Prefecture) announced on November 27 that it has confirmed the effect of detoxifying the new coronavirus with commercially available tea.
It seems that the effect on humans has not been confirmed at the basic research stage, but up to 99% of the virus loses its infectivity when it comes into contact with tea for 1 minute in vitro, and it can be expected as one of the infection control measures.
