Course of the Channels and Point Qualifications

The pathologies of the Channels and their Zang-Fu organs can be understood better if both the external and the internal pathways of the Channels, are studied. For example, the Liver Channel is connected with GV 20 via an internal branch. This can serve as an explanation for the development of headaches on the top of the head, when the Liver function is impaired.
Acupuncture points with specific qualifications have especially strong effects.
