Abstract:
The contents of Zn, Cd, K and Na in 11 kidney tonic Chinese traditional medicines usually used in clinical practice were determined by FAAS. The results showed that element Zn, which is closely related to yang deficiency of the kidney, and the macro elements K and Na, which are essential to human-body, are very rich, but element Cd is lower. The relations between trace elements and the therapeutic efficacy were discussed, and it is concluded that the results are in agreement with clinical usage of medicines by herbalists.
