Codonopsis lanceolatae have been used as one of the traditional remedies as well as food source. We previously reported that in vitro supplementation of Codonopsis lanceolatae water extracts enhanced the splenocytes proliferation compared to the control group. This study, the combined immunomodulative effect of water extract Codonopsis lanceolatae was Seven to eight weeks old mice(balb/c) was fed ad libitum on chow diet and water extract of Codonopsis lanceolatae was orally administrated every other day for four weeks at two different concentrations(50 and 500 mg/kg B.W.). The production of cytokine(IL-2, IL-10 and IFN-), secreted by macrophages stimulated with LPS or not, were detected by ELISA assay using the cytokine kit. The result of ex vivo study showed that the IL-2, IL-10 and IFN- was detected at 500 mg/kg B.W. supplementation group with LPS stimulation in all cases. Also, ratio of IFN-, IL-10 was the range of 37 with mitogen stimulation such as Con A and LPS. In conclusion, this study suggests that Codonopsis lanceolatae extracts may enhance the immune function by regulating the cytokine(IL-2, IL-10 and IFN-) prodution capacity by activated macrophages in mice.
