There are different understandings in classical ancient books on the concept of reinforcing and reducing of the five zang-organs

and there are also obvious differences in the physiological characteristics of the five zangorgans and functions of the five flavors. It is difficult to form a systematic and accurate view of reinforcing and reducing by simply taking the five flavors matching the five zang-organs. In addition

the "character"representing the material basis and the "function" representing the action has precise connection

which also has certain attribute of yin and yang. This paper adopted different perspectives through detesting and desiring of five zang-organs

character and function of yin and yang

to discuss the concept of reinforcing and reducing of the five zang-organs

in order to have a deeper understanding to the reinforcing and reducing of five zang-organs by using five flavors.
