An Analysis of Zhang Xichun's Theory of"Lesser Yang Being the Travelling Part"
Zhang Xichun advocates"lesser yang being the travelling part",Based on the original text of lesser yang meridians in Huang-di's Internal Classic and the order of lesser yang transmission in Treatise on Cold Damage Damages,he argues that"lesser yang being the travelling part"is the hub of the three yang meridians in physiology and connects the meridians and organs in pathology.Zhang Xi-chun believes that the original lesser yang is divided into two parts:hands and feet,which are considered as one meridian.However,the"parts"are not located in the same place,and the procession is unpredictable.The position of lesser yang is between greater yang and yang brightness,but its transmission order is greater yang-yang brightness-lesser yang.When treating lesions in the three yang meridi-ans,Zhang Xichun often uses Minor Bupleurum Decoction and its modified formulas.Although Minor Bupleurum Decoction is the main formula of lesser yang meridians,lesser yang is located between greater yang and yang brightness,and connected to the liver of the re-verting yin and gallbladder.All lesions in the three yang meridians have syndrome of Minor Bupleurum Decoction,so medication should take into account the three meridians,providing ideas for the treatment of typhoid fever and malaria.
