Course
This channel starts from the side of the nose (Point Yingxiang LI20), and ascends to the root of the nose,meeting the Urinary Bladder Channel (at Point Jingming, BL1 ). Then it descends along the lateral side of the nose and enters into the upper gum. Emerging and curving round the lips, it passes downwards and connects with the symmetrical channel at Point Chengjiang(RN24) in the sulcus mentolabiabialis. And it runs along the posterior-inferior side of the parotid gland, through Point Daying(ST5), and Point Jiaehe(ST6) in succession, and then ascends in front of the ear. through Point Shangguan (GB3), the point of the Gall Bladder Channel of Foot-Shaoyang. And finally, it runs along the hairline and reaches the forehead (Point Touwei, ST8).
One of its branches sprouts in front of Daying(ST5), descends to Renying(ST9), and goes along the throat into the supraclavicular fossa. From there it descends through the diaphragm, enters into its pertaining organ, the stomach, and communicates with the spleen.
A straight branch from the supraclavicular fossa descends to the medial border of the papilla mammae. Then it makes its descent along the side of the umbilicus and enters into Point Qiehong(ST30).
One of the branches starting from the pylorus descends through the abdominal cavity, and joins me straight branch at Point Qichong(ST30). From there it descends through Point Biguan(ST31), Futu(ST35), to the knee.Along the anterolateral aspect of the tibia, it goes towards the dorsum of the foot, and then to the lateral side of the tip of the second toe (Point Lidui, ST45).
Another branch sprouting from the region 3 individual cun below the genu(Point Zusanli, ST36), descends to the lateral side of the middle toe.
The branch sprouting from the dorsum o{ the foot (Point Chongyang, ST42)descends into the medial margin of the hallux, and through its tip (Point Yinbai, SP1), connects with the Spleen Channel of Foot-Taiyin.
