The Eight Principal Patterns


A 3-dimensional model for classifying patterns of disharmony.
— the Eight Principal Patterns (ba gang).

The importance of Eight-Principal-Patterns analysis for understanding contraindications.
The vast majority of instances of contraindicated uses occur directly as a consequence of attempting to answer the remedy-for-disease-X question and then trying things at random. Accurate pattern analysis is crucial to the CCM paradigm.
