    ----------------------------------------

    In five element acupuncture this point is reinforced to tonify Kidney deficiencies.

    ----------------------------------------

    Ling Shu Ch. 6 suggests piercing the Jing points of the Yin channels if a disease is in the Yin of the Yang realm (e.g. the sinews and bones). This would mean using this point to treat disorders of the hip, knee and ankle.

    Ch. 7 then suggests using paired needles either side of the tendon to remove a tendon blockage illness, and straight needling to the bone for bone blockage illness. This could be interpreted as using these technique on this point, on either side of the achilles in incidences of injury to this tendon or straight in cases of bone injury, or using them as local techniques while Ch. 6 is a distal point suggestion.

    Ling Shu Ch. 22, On Mania and Madness, advises that when Wind invasion and counterflow causes the limbs to become swollen, profuse sweating, a feeling cold and to be irritated when hungry, then blood is removed from the outer and inner sections of the hand Taiyin and foot Shaoyin and Yangming. If the flesh is cool then it is be done through the Ying-Spring points and if the bones are cold it is to be done through the Jing-Well and Jing-River points.

    Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the Jing-River points should be pierced in late summer or when the disease affects the voice. The seasonal aspect should not be interpreted literally as it describes the voice and musical notes as "controlled by late summer". It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year although late summer is not included in this comparison but presumably has some correlate (maybe late afternoon).

    Ling Shu Ch. 52, On the Wei Qi, considers this point or Zhaohai Kid-6 or Jiaoxin Kid-8 (the text is vague and says 3 cun above or below the inner ankle) to be the root of the foot Shaoyin meridian with the tip being at Shenshu Bl-23 and Lianquan Ren-23.

    ----------------------------------------

    Shang Han Lun, line 292, advises using seven cones of moxa on Shaoyin if the pulse fails to arrive normally in a Shaoyin pattern with symptoms of vomiting and diarrhoea, absence of counterflow but presence of heat effusion. No points are given but Ke Qin suggests this point and Yongquan Kid-1 while Zhang Nan suggests Taixi Kid-3 (Mitchell, Ye and Wiseman, 1999, Shang Han Lun).

    ----------------------------------------

    In Tung acupuncture this point is called Guangming, Bright Light (77.28), and is indicated for all eye disorders, especially if combined with Shui Xiang, Tung's name for Taixi Kid-3 (Chu, 2015).
