Gallbladder Meridian of Foot-Shaoyang

Gallbladder Meridian of Foot-Shaoyang starts from the outer canthus (Tongziliao (GB1) (Tongziliao (GB1))) and ascends to the corner of the forehead (Hanyan (GB4) (Hanyan (GB4))) and then winds downward to the retroauricular region (Fengchi (GB20) (Fengchi (GB20))). It then runs along the lateral side of the neck emerging in front of the Sanjiao Meridian of Hand Shaoyang. It travels behind the Sanjiao Meridian of Hand Shaoyang at the shoulder region and travels further down to the supraclavicular fossa.

The retroauricular branch passes through the ear and emerges in front of the ear at the posterior side of the outer canthus. A branch comes out from the outer canthus, runs downward to Daying (ST5) (Daying (ST5)) and meets the Sanjiao Meridian of Hand Shaoyang at the infraorbital region. Descending and passing through the Jiache (ST6) (Jiache (ST6)), it reaches to the neck and enters the supraorbital fossa to meet with the main line of the meridian. From there it further descends and enters the chest, passes through the diaphragm to connect with liver and enters the gallbladder, forming part of its meridian system. It then travels interiorly in the hypochondriac region, emerging at the lateral side of the lower abdomen near the femoral artery in the inguinal region. Then it curves along the margin of the public hair and runs transversely into the hip region (Huantiao (GB30 ) (Huantiao (GB30 ))).

The straight line of the meridian travels downward from the supraclavicular fossa, and further down to the axillary region. Along the lateral side of the chest and through the free ends of the floating ribs, it meets the former branch at the hip region. It then travels downward along the lateral side of thigh to the lateral side of the knee. Further descending along the anterior aspect of the fibula, it reaches the lower end of the fibula, and the anterior aspect of the lateral malleolus. Following the dorsum of the foot, it terminates at the lateral side of the fourth toe’s tip (Zuqiaoyin (GB44) Jing-Well Point (Zuqiaoyin (GB44) Jing-Well Point)).

The branch splitting from Zulinqi (GB41) Shu-Stream Point, The Eight Confluent Point(Zulinqi (GB41) Shu-Stream Point, The Eight Confluent Point) runs between the 1st and 2nd metatarsal bones to the hairy area of the big toe (Dadun (LR1) Jing-Well Point (Dadun (LR1) Jing-Well Point)) where it communicates with the Liver Meridian of Foot Jueyin.
