Objective] The pathogenesis of HuangQin Tang is discussed little in six meridians syndrome differentiation, and which meridian syndrome does it belong to isn’t clear. So this article tries to discuss the belonging and pathogenesis of it. And the key point of using it in clinic will also be involved.[Method] Combining the observation of efficacy of XiaoChaiHu Tang and HuangQin Tang and the elaboration articles are related to that two prescriptions to analyze the difference of that two prescriptions in pathogenesis.[Result]It’s found that HuangQin Tang and XiaoChaiHu Tang all belong to ShaoYin in six meridian syndrome.But their pathogenesis is different. HuangQin Tang should be used in heat syndrome of ShaoYang disease which caused by heat pathogen of ShaoYang meridian and diarrhea will appear because belly is shocked. However, XiaoChaiHu Tang is used to drive cold pathogen of ShaoYang meridian. [Conclusion]Both of HuangQin Tang and XiaoChaiHu Tang belong to ShaoYang Meridian, but it’s known that HuangQin Tang is used less. And less discussion of HuangQin Tang should be blamed. The more we know on pathogenesis of HuangQin Tang, the better we use it.
