General Theory of the Functional Network of the Five Zang and Six Fu
Within the Inner Canon, the functional network of the Five Zang and Six Fu is built especially from chapters such as the Suwen: Yin Yang Ying Xiang Da Lun, Jin Gui Zhen Yan Lun, Xuan Ming Wu Qi, Wu Zang Sheng Cheng, and the Ling Shu: Ben Shen. Many modern books on the Yellow Emperor’s Inner Canon reproduce these correspondences in tabular form.
The clinical value of this extended Five-Phase / Five-Zang network is not merely classificatory. Multimodal observations gathered from the patient can first be sorted into a smaller number of related families. This reduces the number of competing explanations and helps the physician identify the underlying cause and pathomechanism.
The ancient model assumes that phenomena in the world can be grouped into broad classes according to shared patterns—described in the tradition as things that can “respond and communicate with one another.” In this research framework, one way of thinking about that commonality is through recurring modes or frequency-like properties.
Thus the twelve broad categories and twenty-four dimensions below, when crossed with Five-Phase/Five-Zang correspondences, compress what would otherwise be roughly 120 scattered observations into five large families. This supplies a basis for reasoning such as: which family is currently excessively strong, and which other family is being constrained by it?
When a compact hypothesis can account for several otherwise separate observations at once, the physician is working in the same broad logical direction as a detective. In modern analytical language, this can be compared with backward reasoning: begin with the observed consequences and infer the most coherent common cause.
