    Superficial Innervation: Tibial nerve from sciatic nerve (L4 - S3)
    Dermatome Segment: L4

    One of the most important points for tonifying the yin aspects of the spleen, liver and kidneys together. Since spleen and liver have strong influence over blood and all three influence the menstrual cycle it is a very strong point for nourishing and cooling blood, especially menstrual blood.


    Its ability to regulate urination has seen electro-acupuncture at this point approved by NICE as "percutaneous tibial nerve stimulation" (PTNS), with the second electrode being a pad applied to the foot (probably Shuiquan Kid-5). See also Sacral Nerve Stimulation for a similar form of modern treatment at Zhongliao Bl-33 over the third sacral foramen.


    Ling Shu Ch. 23, On Heat Diseases, recommends using this point to stop an extreme sweat brought by treatment.

    Ling Shu Ch. 52, On the Wei Qi, considers this to be the root of the foot Taiyin meridian with the tip being at Pishu Bl-20 and the root of the tongue.


    In Tung acupuncture this point is known as Ren Huang, Human Emperor (77.21) and is often combined with Di Huang, Earthly Emperor (77.21), 4 cun above, 1 cun above Lougu Sp-7, and Tian Huang, Heavenly Emperor, at Yinlingquan Sp-9 to make Xia San Huang, the Lower Three Emperors. They all treat many disorders of the Spleen, Liver and Kidney, this one especially focuses on the Liver (Chu, 2015).
