Abstract：The theory of Shaoyin and Shaoyang as pivots reveals the core mechanism of qi movement of yin and yang in the human body. Shaoyang governs the ascent，descent，exit，and entry of qi between the exterior and interior； Shaoyin dominates the intersection and mutual transformation of water and fire. Together，they form the pivots regulating water，fire，yin，and yang of the human body，maintaining the physiological state of balanced yin and consolidated yang. Based on this theoretical framework，the essential pathogenesis of Parkinson's disease lies in root deficiency and branch excess induced by dysregulation of the two pivot systems of Shaoyin and Shaoyang. The treatment principle is to harmonize Shaoyang for smoothing qi movement，and warm Shaoyin to consolidate the origin and tonify primordial qi. This study proposes therapeutic strategies for Parkinson's disease from the perspective of pivoting Shaoyang and Shaoyin.
