    Origin of the Chong Mai (Su Wen, Wang Shu He).


    Location of the yin qiao mai in Zhang Boduan's Book of the Eight Vessels on alchemical working (Wang Mu, 2011, Foundations of Internal Alchemy).


    Yuen (2005, 3 Spirits & 7 Souls) describes this point and Changqiang Du-1 as the Po Men (gate of the soul) where the Po (corporeal soul) exits the body at death through the anus.

    This point is also indicated in problems with the Fourth Level of Manifestation of the Soul, or the Anahata chakra, concerned with creation, "mind becoming matter" and the ability to turn ideas into actions that have consequences. This manifests in hopelessness, cynicism and inability to see reality as illusion.
    The other points in this set are Baihui Du-20, Huiyang Bl-35.
    During the Ming Dynasty this point was replaced with Yinjiao Ren-7 as points around the genitals became taboo (Ibid.).


    Ghost Points:
    The fourth trinity of Ghost Points, consisting of this point, Quchi LI-11, Shangxing Du-23 and Huiqian or Yintang, is concerned with self-destructive behaviour, self-harm and attempts at suicide.

    This point is usually treated with indirect moxa in order to break the seal that ghost has used to trap your Jing Essence. It is characterised by extreme depletion and wasting, up to the point of paralysis and comatose states (Ibid).


    Ge Hong (4th century) recommends for Dian Kuang with symptoms of falling fits and manic frenzy that the practitioner should cauterise Qugu Ren-2 with three cones of moxa and when the subject urinates he is cured. This may be complemented with two groups of seven cones burned along the seam behind the testicles at this point (Strickmann, M, 2002, Chinese Magical Medicine, p. 240, Stanford University Press).


    Medieval phlebotomy point (John de Foxton, 1408: Liber Cosmographiae,; Hans von Gersdorff, 1517: Feldtbüch der Wundartzney,, although Foxton's diagram appears to point between the penis and testicles of the zodiac man, slightly anterior to the Chinese location and Gersdorff appears to have 4 points on the genitals themselves.


    Lad and Durve (2008) in Marma Points of Ayurveda have no points at Huiyin Ren-1 but locate three points on the genitals which may be related to this point since there are no acupounts on the genitals.

    In men the Medhra point is on the dorsal surface of the midpoint of the glans penis and in women the Yoni Jihva is at the tip of the clitoris. They associate these with Apana Vayu, Vyana Vayu and Ranjaka Pitta with the functions of:
    - Acts on the shukra or artava dhatu
    - Stimulates ojas

    The other two points are located at the centre of each testicle in men and called Vrushana or at the midpoint of the labia majora on each side in women and called Yoni Oshtha. They are associated with Apana Vayu and Vyana vayu and have the following actions:
    - Acts on shukra or artava dhatu
    - Stimulates ojas
    - Relieves pain locally
    - Awakens sexual energy

    One of the methods for stimulating these points is the Ashvini mudra where the anus is contracted inwards, creating pressure at these marma which would involve the use of Huiyin Ren-1.


    In Tibetan medicine:
    Moxa point (AMNH, Tibetan Medical Paintings)


    In Thai massage:
    Main acupressure point along the Kitcha sen line running from the navel Shenque Ren-8 to this point at the perineum. Called the Pikkatun in men and the Kitchana in woman it is indicated for issues of sexual function and fertility. It is not treated with direct pressure but may be stimulated with warm herbal compresses (Salguero & Roylance, 2011, Encyclopedia of Thai Massage).


    If gates along the microcosmic orbit are considered in terms of qabalistic sephirot then this point would be equivalent to Yesod.


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


    This point can be pierced and is known as a guiche. The origins are said to come from Samoa or Tahiti but both are unlikely (Morrison, 1998: Piercing History, Painful Pleasures).
