    In five element acupuncture this point is reduced to drain excess in the Heart.

    Ling Shu Ch. 6 suggests piercing the Ying and Shu points of the Yin channels if a disease is in the Yin of the Yin realm (e.g. the Zang organs) suggesting this point and Laogong Pc-8 in diseases of the Heart (the Heart had no channel in Ling Shu, if disease had reached that far death was considered immanent).

    Ling Shu Ch. 9, On Ends and Beginnings, advises that in the case of Heat associated with receding Yin Qi the Yang conduit should be pierced once and the Yin conduits twice. Based on other recommendation to use the He-Sea of the Yang conduits (Ch. 19) and the Yuan-Source with the Ying-Spring points (Chs. 6, 19 and 24) to clear Heat from the Zangfu, that would suggest this point, Tianjing SJ-10 and Laogong Pc-8 as a protocol to clear Heat in the Pericardium/San Jiao. Next it advises that in Cold associated with receding Yang Qi the Yang should be pierced twice and the Yin once but no such obvious protocol is evident for this situation.

    Ling Shu Ch. 19, on the Four Seasonal Qi, advises using the Shu-Stream points, unless the diseases are in the Fu organs, in which case the He-Sea points are chosen.

    Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the Shu-Stream points should be pierced in summer or when the disease becomes milder and then more severe again. The seasonal aspect should not be interpreted literally as it describes the time periods of weakness and severity as "controlled by summer". It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year with afternoon corresponding to summer. Only five channels are discussed so this point must have served the for the Heart too.

    In Lingmen opposite needling for blood in urine due to Heat in Heart Blood one needle is inserted from Daling Pc-7 to Ximen Pc-4 while another is inserted in the opposite direction from Ximen Pc-4 to Daling Pc-7 (Liu Yan, 2008, Diagrams of Acupuncture Manipulations, p.133).

    In Ling Ze pointing to xi needling for palpitations one needle one needle is inserted from Daling Pc-7 to Ximen Pc-4 while another is inserted in the opposite direction from Quze Pc-3 to Ximen Pc-4 (Liu Yan, 2008, Diagrams of Acupuncture Manipulations, p.132).

    Ghost Points:
    The second trinity of ghost points, consisting of this point Shenmai Bl-62 and Fengfu Du-16, is concerned with the ghost trying to get you to search for the remnants of its past, either by dreamwork or literally going to places and seeking people it longs for. This is the most Yang phase of possession with many signs of Wind and Heat leading to agitation, uncontrollable movement and outbursts.

    The name for this point Guixin, Ghost Heart, represents that the ghost is beginning to control the emotions of the person leading to sudden outbursts from Heat in the Blood. Therefore this point would be bled (Yuen, 2005, 3 Spirits & 7 Souls).

    This point is also 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 open the chest enabling the mind's descent to the Kidneys (Source points connect to the Kindeys). The others in the set are Shuaigu GB-8, Shanzhong Ren-17 and Jimai Liv-12 or Ququan Liv-8 (Yuen, 2005, 3 Spirits & 7 Souls).
