Recently, combination therapy with acupuncture and medicine as a practical strategy to treat diseases has gained increasing attention. The present study aimed to investigate whether acupuncture stimulation at ST.36 had a potential impact on the pharmacokinetics and tissue distribution of lignans. An HPLC‐ESI/MS analytical method was established and successfully applied to a comparative study of drug concentration in plasma and tissues of three lignans. The parameters area under the plasma concentration–time curve from time zero to the final measurable point and from time zero to infinity, and peak concentration were significantly increased, with a prolonged mean residence time and a corresponding decrease in clearance in comparision with the Schisandra ‐alone group. Additionally, tissue concentrations of three lignans were improved in the group with acupuncture, especially in liver. The results indicated that acupuncture has a synergistic effect on the pharmacokinetics and tissue distribution of the three lignans, which could postpone their elimination, resulting in a longer blood circulating time in rat plasma and prolonged residence time in target tissues, leading to higher tissue concentration. The findings provide some scientific evidence for the mechanism of the combined use of acupuncture and herbal medicine. Furthermore, we suggest that acupuncture and its combination with herbal medicine should be investigated further as a possible adjuvant therapy in clinical treatment for liver injury.
