(a) Images of the SARS-CoV-2 plaques incubated with different dilutions of Covid-Organics. The dose is expressed by percentage of the raw drink. (b) Concentration-dependent inhibition of SARS-CoV-2 infection using different extracts. Here, SARS-CoV-2 was preincubate with indicated compounds for 45 min and the mixture subsequently added to VeroE6 cells for another 45 min. Then, the cells were washed with PBS to remove unboundvirions and covered with Avicel overlay medium for three days until plaque formation. Please note that the testing protocol is different from Ref. 16. Values are expressed as mean ± SD, n = 3
