A dynamic study on reversal of multidrug resistance by ginsenoside Rh2 in adriamycin-resistant human breast cancer MCF-7 cells

► QCM dynamic measurement for cytotoxicity research owns good reliability. ► Ginsenoside Rh2 could inhibit growth of MCF-7/ADR cells. ► The ADR-G-Rh2 combination presented higher inhibition efficiencies. ► Reversal of multidrug resistance in MCF-7/ADR cells could be achieved by G-Rh2.
