    Notes:
    As back-shu point of the liver this is the main point on back for regulating all aspects of Liver function, smoothing qi, cooling heat and pacifying wind emanating from liver dysfunction.

    Ling Shu Ch. 51, On the Back Transport Points, advises that the back Shu points of the Yin organs should be pressed. If this elicits a response, either pain or the relief of a existing pain, then these points should be supplemented or drained with moxa and not pierced. To supplement with moxa the cone is to be left to burn down naturally, to drain it is to be blown on to make it burn more fiercely.

    Ling Shu Ch. 52, On the Wei Qi, considers this to be the tip of the foot Jueyin meridian with the tip being at Zhongfeng Liv-4.

    One of the Aggressive Energy Drain points in five element acupuncture, along with Feishu Bl-13, Jueyinshu Bl-14, Xinshu Bl-15, Pishu Bl-20 and Shenshu Bl-23, indicated where psychological or emotional issues are blocking treatment. They are needled from left to right, top to bottom, with the exception of Xinshu Bl-15 that is needled last, along with controls outside the Bladder channel at the same levels. If aggressive energy is present the points should become redder than the test points and are left until the redness disappears. If not then needles can be removed and treatment continued.
