The historical development of endogenous wind （内风） is traced with time as the thread， based on the progression of factors such as syndromes， causes of disease， and pathogenesis. It is believed that the concept of wind syndrome originated in

The Inner Canon of Yellow Emperor

（《黄帝内经》）， encompassing both exogenous wind

（外风） and endogenous wind syndrome. Over time， exogenous wind syndrome gradually evolved into mild syndromes and seve

re syndromes， while endogenous wind syndrome emerged from severe syndromes of exogenous wind. Endogenous wind syndrome has both syndrome and pathogenic attributes， and its theoretical system has gradually become more refined. Based on the theories of ancient and modern medical practitioners， and combining the holistic perspectives with

Xiang

（象） thinking， it is proposed that endogenous wind has both physiological and pathological distinctions. The physiological endogenous wind refers to the liver's moderate dispersing and regulating function， which helps to distribute

qi

（气）， blood， and body fluids， while pathological endogenous wind arises from abnormal liver dispersal. Therefore， in clinical practice， different treatment methods， such as tonifying， unblocking， and warming， can be applied according to the differentiation of deficiency and excess in the pathogenesis.
