Commentary for Geguan BL-46

Guguan BL-46 is at the same level as Geshu BL-17, which is the Gathering-Hui point of the Blood. Therefore, it has many actions similar to BL-17. 

Most importantly, it regulates Qi in diaphragm between the Upper and Middle Burner. To be more specifically, it removes Qi Stagnation in the Upper Burner, characterized by chest and diaphragm fullness and oppression. It also descends Rebellious Stomach Qi in the Middle Burner with typical symptoms such as vomiting, difficult ingestion and belching. 

On the other hand, it is used as a local point to remove obstructions from the Channel, so as to ease pain and stiffness in the spine, back and joint area.
