":In vitro studies indicated that the combination of betulinic acid, parthenolide, honokiol and ginsenoside Rh2 exhibited a synergistic action. When these four natural products were loaded into liposome systems, we observed an increased effect. The relative action was also observed in vivo. The cisplatin group presented obvious kidney damage, whereas both cocktail therapy and cocktail liposome therapy were safer. Conclusion: Therefore, we propose cocktail liposome systems may provide a more efficient and safer treatment for lung cancer."
