Effects of Traditional Kampo Drugs and Their Constituent Crude Drugs on Influenza Virus Replication In Vitro: Suppression of Viral Protein Synthesis by Glycyrrhizae Radix

Figure 3

Measurement of infectious titers and calculation of IC₅₀. Virus infectivity in the medium prepared as described in the legend of Figure 2 at an m.o.i. of 0.2 was measured. The logarithms of infectious titers and Kampo drug concentrations were plotted, and IC₅₀ values were calculated on the basis of a linear approximated line.
