    Ling Shu Ch. 22, On Mania and Madness, recommends removing blood from the moving vessels to the left and right of this point if an abundance is felt in the early stages of a madness before any of the specific patterns mentioned in the chapter have developed.

    Ling Shu Ch. 24, On Counterflow Diseases, advises using this point for discharge of blood (Unschuld, 2016) or bloody stool (Wu & Wu, 2010).

    Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the He-Sea points should be pierced in autumn or when the disease is a result of immoderate diet. The seasonal aspect should not be interpreted literally as it describes the flavours as "controlled by autumn", probably referring to the mouth, nose and throat where the metal channels run. It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year with evening corresponding to autumn. Perhaps the most likely interpretation is during middle age, the autumn period of life, when the effects immoderate diet are likely to start to show.


    This point is indicated for issues relating to the Third Level of Manifestation of the Soul, or the Manipura chakra, manifesting in difficulties switching the mind off, becoming unconscious and sleeping. The problem is that the Lung qi is unable to descend into the formless darkness of the Kidneys or the Kidneys are unable to hold it here.
    The specific purpose of this point is to prevent the Kidneys giving Jing to the Liver (Water point), arousing the Blood and causing dream states. The others in the set are Shuaigu GB-8, Daling Pc-7 and Shanzhong Ren-17.
    In pre-Ming times Jimai Liv-12 was used until points around the genitals became taboo (Yuen, 2005, 3 Spirits & 7 Souls).


    Lad and Durve (2008) in Marma Points of Ayurveda call this point medial Charana and associate it with the doshas: Apana Vayu, Vyana Vayu and Shleshaka Kapha.

    They give the following functions:
    - Promotes circulation in lower extremities
    - Acts locally to relieve knee pain
    - Supports the kidneys, bladder and adrenals

    A lateral Charana is located at Yanglingquan GB-34.
