The subject of etiology is the study of the causative
factors of disease, whilst the study of pathogenesis concerns the actual
bodily processes whereby disease occurs, develops and changes.
Traditional Chinese medicine holds that there is normally a state of relative
equilibrium between the human body and the external environment on the one hand,
and among the zang - fu organs within the body on the other hand. If
external influences exceed the powers of adaptability of the organism, or
if the body itself is unable to adjust to changing conditions, then this
relative equilibrium will be lost, and disease will develop
