    Notes:
    One of the principle acupuncture points for fostering the original qi, improving jing (essence) and nourishing the kidneys.

    Equal to Qihai Ren-6 for tonifying the Kidneys but has a stronger effect on nourishing blood, yin and jing (essence) rather than qi or yang. Both points share the name of Dantian referring to the lower energy centre.

    If the deqi sensation can propagate downwards to the genitals, this is considered especially effective for treatment of reproductive disorders. This is best achieved by angling the needle inferiorly in the direction of the genitals.

    Possible location of lower dan tian (Deadman, 2001). See also Qihai Ren-6 and Shenque Ren-8.

    Ling Shu Ch. 21, on Cold and Heat Diseases, advises this point for numbness and weakness of the four limbs due to injury with blood loss, a fall or attack by Wind and Cold. The same paragraph also recommends supplementing the three Yin conduits in instances of bony Bi when all joints are useless and ache with sweating and Heart vexation. The suggestion is that this point is to be used as an addition in those special circumstances due to its influence on all three leg Yin channels.

    In Tung lineage acupuncture the Bowel Nest 23 (Fu Chao Er Shi San) are a group of points located in a line at 1 cun intervals between Ren-2 and Ren-10. An additional eight points on either side form a 4x5 grid at the levels of Ren-9 to Ren-5, also at 1 cun intervals. Ren-8, on the navel, is not included.

    They are pricked using Tung's method in local disorders of pain, stagnation and heat in the abdomen such as uteritis, nephritis, umbilical area pain, enteritis, appendicitis and intestinal cancers (McCann, 2014, Pricking the Vessels).

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

    Lad and Durve (2008) in Marma Points of Ayurveda locate a point between here and Shimen Ren-5 called Basti and associate it with Apana Vayu, Vyana Vayu, Ranjaka Pitta and Kledaka Kapha.

    They give the following functions:
    - Regulates bladder and treated genitourinary dysfunction
    - Regulates apana vayu
    - Relieves pain
    - Increases circulation and enhances function in the pelvic organs

    In Indian Ayurvedic and Siddha traditions this would be the location of the Malamarmmam point, literally the "excretion blocking vital point" which arrests defecation if struck (Sieler, 2015, Lethal Spots Vital Secrets, p.41).

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

    If gates along the microcosmic orbit are considered in terms of qabalistic sephirot then this point would be equivalent to hod along with Qihai Ren-6.
