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

    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 shoulder, elbow and wrist.

    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 palmaris longus or flexor carpii radialis in incidences of injury to these tendons or straight in cases of bone injury (although this point goes between the radius and ulnar). Alternatively they may be read separately, using these as local techniques to remove the blockage while Ch. 6 is a distal point suggestion.

    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). Only five channels are discussed so this point must have served the for the Heart too.
