    Notes:
    Possible location of the middle dan tian or Yellow Court (huangting) in alchemical practice, at the level of the heart, or where heaven (upper dan tian) and earth (lower dan tian) meet. See also Juque Ren-14.

    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 clear obstruction in the chest preventing the mind's descent. The others in the set are Shuaigu GB-8, Daling Pc-7 and Jimai Liv-12 or Ququan Liv-8 (Yuen, 2005, 3 Spirits & 7 Souls).

    This is also one of the points in the 3 Treasures treatment along with Shanzhong Ren-17 and Yongquan Kid-1.
    The alchemist Ge Hong used moxa on these points for exorcism of ghosts ("Gui") (ibid.).

    When using the Bladder or Small Intestine Divergent meridians to expel a pathogen a band around the chest at this point, including Shendao Du-11, Xinshu Bl-15 and Shentang Bl-44, should be treated with Gua Sha before commencing needling (Cecil-Sterman, 2012, Advanced Acupuncture).

    Medieval phlebotomy point (John de Foxton, 1408: Liber Cosmographiae, maa.cam.ac.uk)

    In Tibetan medicine:
    May be treated with burnt cones of edelweiss flowers (Trah-wah) on crushed garlic for mental conditions (Bradley, 2000: Principles of Tibetan Medicine).

    The Front Mu points make likely locations for application of leeches to reduce fevers according to François Broussais' (1772–1838) philosophy who believed in placing them over the diseased organs to reduce inflammation (Greenstone, 2010, The history of bloodletting, BCMJ, Vol. 52, No. 1, Pp 12-14).

    If gates along the microcosmic orbit are considered in terms of qabalistic sephirot then this point would be equivalent to gevurah. Other comparisons place tipharet here, over the heart which I have placed lower, at
    Juque Ren-14, the front Mu of the Heart.

    In Hindu tantrism this point would be the location of the kshetram or activation point of the Anahata chakra.

    This is a marmmam vital spot in Indian martial arts and medicine (Ayurvedic and Siddha) known as Trisangupuspam, "three conch flower" and is popular in Malayalam cinema. Striking it causes "the eyes to pop out, while the victim, screaming unknowingly, spits blood (in Sieler, R. 2012, Lethal Spots, Vital Secrets, p.41).
