Notes:

At the end of a Liver Luo treatment this point is needled, deqi grasped and removed immediately to normalize the circulation of blood (Cecil-Sterman, 2012, Advanced Acupuncture).

There are several points in Tung acupuncture located on the inner thigh for which this point is the closest TCM reference point, although they are not really located in relation to this. Collectively they are known as the Shang San Huang, upper three yellows. The first is Ming Huang, Bright Yellow (88.12), located as opposite Fengshi GB-31, with Tiang Huang, Heavenly Yellow (88.13), 3 cun above and Qi Huang, Cycle Yellow (88.14), 3 cun below. They are indicated for Liver disorders, especially ones affecting the eyes and often combined with Huo Ying and Huo Zhu, near Xiangjian Liv-2 and Taichong Liv-3 (Chu, 2015).

The lowest of these points has another two located in relation to it, Huo Zhi, Fire limb (88.15), and Huo Quan, Fire Through (88.16), located 1.5 cun proximal and distal to Qi Huang. Their indications are for patterns of Liver Heat (Chu, 2015).

Reference Notes:

Basic information on location, needle depth, TCM actions, indications and combinations is taken from Deadman et al (2001): A Manual of Acupuncture with additional anatomical information researched by reference to Gray's Anatomy (38th Ed., 1995) unless otherwise referenced. Images were found on acupunctureschoolonline.com and can be traced back to Claudia Focks (2008) Atlas of Acupuncture originally. I cannot claim any credit or rights over them.
