    Dermatome Segment: L2

    Notes:
    Mainly used for treatment of heat whether excess or deficient and tonification of Kidneys.

    Possible location for the middle barrier of internal alchemy (Deadman, 2001). See also Shendao Du-11.

    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).

    This point is also indicated in issues with the Second Level of Manifestation of the Soul, or Svadhishthana chakra manifesting in deficiency in ability to make subconscious associations, along with Jingming Bl-1 and Yongquan Kid-1. They represent individuality, ability to see polarity, make separations and move into the world (Yuen, 2005, 3 Spirits & 7 Souls).

    In "xiangwei needling" the Du is needled transversely against the direction of the channel in order to reduce excess conditions, in this case of the urinary and reproductive systems, sciatica and disorders of the lower limbs (Liu Yan, 2008, Diagrams of Acupuncture Manipulations, p.121).

    Master Tung's Three Rivers (San Jiang) are three lines of points, one along the midline below each spinous process from L1 to S2 with the another two either side 3 cun lateral to the midline from L2 to S2. They are pricked to bleed a spot of blood.
    They relate to the water phase and Kidneys and are indicated for lumbar pain and conditions of the abdomen, bowels and uterus. Those 3 cun from the midline can also be used for sciatica and as distal points pain of arm, elbows or shoulders (McCann, 2014, Pricking the Vessels).

    In Tibetan medicine:
    Edelweiss flowers are burnt in cones like moxa over crushed garlic at this point as the common point for the five vital and six hollow organs. It helps cold diseases related to all these organs (Bradley, 2000: Principles of Tibetan Medicine).

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

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