ABSTRACT
It is generally known that oriental medicine is based on the concept of deficiency and excess to explain disease in a complex living system. However, a disease model based upon the expression of the relationship between the rhythm of the five basic elements and the living body's control system has not been proposed. Therefore, we investigated this relationship by modeling “Kyo-Ja” and “Jitsu-Ja” on abnormal rhythms of the five basic elements.<BR>We constructed models that always reflect changes in the rhythm of the five basic elements to show that disease occurs by breaking these control systems. The present model suggests that treatments of disease should not only incorporate the characteristics of the five basic elements but should also consider the course of a disease and the patient's overall condition.
