The paper introduces professor WANG Xingkuan′s experience in treating constraint syndrome. He believes that liver and gallbladder failing to govern qi flow

phlegm-heat harassing the interior

and insufficient qi and yin are the common causes of constraint syndrome. Liver and gallbladder govern the free flow of qi

therefore the dysfunction of these two organs leads to the constraint and stagnation of the qi; as phlegm-heat harasses the interior and heart spirit

the soul confronts with restlessness; when qi and yin are insufficient

there is lack of moisture and nou-rishment for heart and lung

all of which mentioned above explain the pathogenic mechanism of constraint syndrome. In terms of therapeutic methods

he puts forward the theory that "to treat liver for miscellaneous diseases"

and advises to soothe the liver and promote gallbladder function

to clear heat and dissolve phlegm

and to boost qi

nourish yin

and calm the mind. Besides

Chaiqin Wendan Decoction（柴芩温胆汤） and Baihe Anshen Decoction（百合安神汤） are recommended.
