Using flow cytometry the authors analysed the effect of 24 Chinese medicinal herbs (CMH) in compound recipe on proliferation index (PI), DNA index, protein index and ratio of various phases in cell cycle of human lung adenocarcinoma cell (SPC-A-1), The PI were more than 20%, in 4 CMH, while 3 CMH such as Gynostemma pentaphyllum, Glehnia littoralis, Panax Ginseng, could strengthen the body resistance. That suggested using CMH of strengthening body resistance not only served as conventional tonice but also as tumor cell inhibitor. Meanwhile the action point of 24 CMH on cell cycle were different. Therefore according to these results a new recombined Chinese recipe would be more effectively used for clinical practice.
