    Ling Shu Ch. 10 describes the diseases relating to the Luo emanating from this point as:
    Repletion: The back is stiff
    Depletion: The head feels heavy
    (Unschuld, 2016).

    Ling Shu Ch. 22, On Mania and Madness, advises burning twenty moxa cones at this point if the blood is not excited.
    The text says to extract the blood when the disease sets in, store it in a gourd and watch it when the disease strikes again. If the extracted blood is excited and moves then blood is let, if not then this point is cauterised. Something feels like it has been lost in the translation because this was most likely written by an experienced physician and no blood stored in a gourd would ever be excited. Maybe it means to extract blood in the beginning and then observe the blood in the patient's vessels (the Luo and complexion). If it is excited, they become manic and the skin flushes, then to let it out. If it does not and they remain pale and heavy headed then nourish the Luo with moxa at this point.


    Location of the yang qiao mai in Zhang Boduan's Book of the Eight Vessels on alchemical working, and probably location of the lower barrier (Weilu, Barrier of the Caudal Funnel) at the lowest section of the spine (Wang Mu, 2011, Foundations of Internal Alchemy)


    Yuen (2005, 3 Spirits & 7 Souls) describes this point and Huiyin Ren-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 on the 3rd trajectory of the Chong mai connecting the Chong with the Du for Invigorating Yang in cases of Bi Obstruction due to Blood Stagnation (Yuen, 2005, The Extraordinary Vessels).


    Avicenna describes cupping at this point in his treatise On Cupping:

    "Cupping the anus brings fluids from all over the body, including the head. It is good for the intestines, corruption of menstruation, and lightness of the body." (Aspects of Treatment According to General Diseases, 22nd section in Abu-Asab, Amri & Micozzi, 2013, Avicenna's Medicine)


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


    In ayurvedic medicine:
    Guda marma point
    Size: 4 angula (cun)
    Structure: Muscle
    Effect of Injury: Fatal (sadhyapranahar marma)
    (Harish Johari, 1996, Ayurvedic Massage, Sanatan Society; Anupama Bhattacharya, n.d. Marma Shastra)


    In Hindu tantrism this point would be the likely equivalent of the Muladhara chakra.


    Lad and Durve (2008) in Marma Points of Ayurveda locate a point at the tip of the coccyx called Trik (although they do not connect it with Du-1 for some reason) and associate it with the doshas: Apana Vayu, Ranjaka Pitta and Kledaka Kapha.

    They give the following functions:
    - Relieves pain
    - Benefits urinary and reproductive systems
    - Benefits pelvic floor
    - Stimulates Kundalini energy


    In Siddha medicine some practitioners consider this a "whole body relief spot" (carvanka atankal) able to stimulate all vital spots at once (Sieler, 2015, Lethal Spots, Vital Secrets, p.87).

    Adopting a deep squatting position known as varakacanam or "the pose of the wild boar" can protect the Muladhara chakra located here and in turn protect all vital spots in the body (ibid. p.114).
