Yiqihuayu Decotion is effective for acute ischemic stroke clinically, but there is lack of sufficient and reasonable explanation of its intervention effects currently. In order to further clarify the main pharmacodynamic substances of Yiqihuayu Decotion in the treatment of acute ischemic stroke, this study intends to carry out a non-randomized, controlled clinical trial. The primary hypothesis is that, compared with the control group, Yiqihuayu Decotion will produce serial changes in plasma metabolites at pre-dose and 9 days, as well as urine metabolites at pre-dose, 8 days, 9 days and 10 days. The serial changes may be the potential support to explain the intervention effect of Yiqihuayu Decotion. After enrollment, all participants will undergo a 2-day Traditional Chinese Medcine washout period to ensure that the results of pharmacodynamic substances will not be disturbed.
The main purposes of this trial are to analyze the pharmacodynamic substances and the effects of Yiqihuayu Decotion for acute ischemic stroke. The trial is a non-randomized, controlled clinical trial.
