This paper summarized the experience Professor ZHOU Ping’an in treating achalasia. ZHOU believes that achalasia belongs to the "dysphagia"in traditional Chinese medicine（TCM）

and the root cause lies in the tension of the cardiac sphincter

which should be treated with the "endogenous wind"theory. The disease is located in the spleen and stomach

and is closely related to the liver. Then deficiency of yin and blood and hyperactivity of liver yang are the key to the occurrence of endogenous wind. Thus relieving spasm by calming endogenous wind should be consistent throughout the process of treatment. The methods of dissipating phlegm and descending qi

and activating qi flowing

dissipate blood stasis and removing obstruction in collaterals should be applied with syndrome differentiation. For the patients with hyperactivity of liver yang leading to endogenous wind

modified Tianma Gouteng Decoction was frequently used. For those with excess syndrome resulted from deficiency and wind-phlegm blocking collaterals

the medicinal insects such as Lumbricus

Scorpio

Scolopendra are used to enhance the function of eliminating the wind

reducing phlegm and expelling stagnation.
