This Shop Talk is a discussion of the differences between the Zangfu organ system and that of the Jingluo.
A brief history is given, as are mentions of the differing relationships between the Heavenly Stems and Earthly Branches with regard to the Zangfu organs and Jingluo channels.
An example of this is that the internal Zangfu organ Lung is attributed to Metal; whereas the Hand Taiyin Lung channel is attributed to Yang Wood. The differing Five Phase natures of the internal Zangfu organs and the more external Jingluo system, is actually a clear reflection of their different anatomical functions in regard to the overall Chinese Medicine anatomy of the human body. That is to say, the internal organs are the body's way of assimilating and storing, whereas the Jingluo system is one that enables a discrete individual to maintain a dynamically homeostatic state in the context of a greater external environment, an environment which varies along the number of different parameters.
