Objective: To investigate the effect of Compound Jaogulan Yizhi Granules(CJG) on memory improvement in people. Method: One hundred and six participants were randomly assigned to experiment (53 cases) and control (53 cases) groups

and their memory quotients (MQ) were evaluated with clinical memory scales. The test was conducted by following the method of Technical Standards for Testing and Assessment of Health Food in Improving Memory Function (2003). Result: The MQ scales of experiment and control groups were 69.09±16.90 and 69.13±15.72 respectively before testing; the MQ scales of experiment and control groups were 90.13±16.07 and 73.33±14.85 respectively after testing. Before the experiment

the MQ scales showed that there was no a significant difference among the experiment groups compared with the control groups. After the experiment

the MQ scales of the experiment groups was significantly higher than that in the control groups (P<0.05); the MQ scales of the experiment groups was significantly higher than before the test of itself (P<0.05). Conclusion: CJG has the effects of memory improvement in our experiment.
