Effects of astragali radix on the growth of different cancer cell lines

Figure 2 Effect of AR on AGS viability. AGS cells were treated with different concentrations of AR for 48 hrs and cell viability was measured with trypan blue. At or below the concentra-tion of 50 µg/mL, AR was not cytotoxic to AGS cells. But at the concentration of 100 µg/mL, it showed cytotoxicity on AGS.
