" Metaphysics" is a philosophical perspective different from mechanical materialism

and the Chinese philosophy and traditional Chinese medicine′s view of the human body as " body-qi-spirit" embodies a " metaphysical" cognitive pattern. This paper takes the content of

General Treatise on Causes and Manifestations of All Diseases

·

Wind Diseases

as an example to analyze and compare the cognitive evolution process of wind diseases in

General Treatise on Causes and Manifestations of All Diseases

. It is argued that the

General Treatise on Causes and Manifestations of All Diseases

constructs a body model characterized by " metaphysics" where the meridian system connects the entire body to facilitat

e the flow of qi and blood

with the organs serving as the storage places for essence-qi. Through the analysis of the symptoms of stroke

it reveals the specific application of this body model in the theory of disease mechanisms. The meridian tendons

as the subordinate parts of the meridian system

become the physical basis for the explanation of stroke with their substantive existence. It is thus determined that

General Treatise on Causes and Manifestations of All Diseases

has perfected the two-layer space of " metaphysical-physical" body structure of the theory of disease pathogenesis

laid the foundation for the theory of disease mechanism with the state of qi and blood as the focus of discussion

and constructed a model of disease diagnosis and treatment

which is " disease-symptom-etiology and pathogenesis-treatment" .
