Anti-VZV activity of kaempferol. (A) Structure of kaempferol. (B) HFFs were inoculated with serially diluted cell-associated VZV-YC01 and treated with kaempferol at the indicated concentrations. Cells were re-treated with the same concentrations of kaempferol 3 days after inoculation. At 6 days after inoculation, cells were stained with 0.3% crystal violet and the number of plaques was counted.
