No cytotoxicity induced by Pingwei Pill treatment. A Hemolysis analysis of the combination of Pingwei Pill with colistin at the indicated concentrations for sheep RBCs. RBCs incubated with PBS and water were used as negative (−) and positive (+) controls, respectively. Cytotoxicity of Caco-2 cells (B) and HeLa cells (C) by determining the LDH released into supernatants following incubation of host cells with various concentrations of Pingwei Pill. Cytotoxicity of Caco-2 cells (D) and HeLa cells (E) by determining the LDH released into supernatants following incubation of host cells with the indicated treatment. NS, no significance
