Channels
### Pathology of the Channels
The Channels and their affiliated Zang-Fu organs are closely connected with each other and play an important role in human physiology and pathology. Channel disorders can cause disorders of the Zang-Fu organs and disorders of the Zang-Fu organs can cause Channel disorders. In the practice, the connection between Channels and Zang-Fu organs is often very obvious. We can also often notice that Channel disorders originate as a consequence of Zang-Fu organs disorders. The treatment should include both aspects, treating the root: the disorder of the Zang-Fu organs, as well as the branch: the Channel disorder. Channel disorders can occur as a result of: Zang-Fu organ disorders; penetration of Pathogenic Factors; disturbed Substances; post-trauma or strain. For the symptoms associated with the disorder of a particular Channel, please refer to the TCM Information (TCM-Tutorial).
