    Ling Shu Ch. 6 suggests piercing the Ying and Shu points of the Yin channels if a disease is in the Yin of the Yin realm (e.g. the Zang organs) suggesting this point and Yuji Lu-10 in diseases of the Lung.

    Ling Shu Ch. 9, On Ends and Beginnings, advises that in the case of Heat associated with receding Yin Qi the Yang conduit should be pierced once and the Yin conduits twice. Based on other recommendation to use the He-Sea of the Yang conduits (Ch. 19) and the Yuan-Source with the Ying-Spring points (Chs. 6, 19 and 24) to clear Heat from the Zangfu, that would suggest this point, Quchi LI-11 and Yuji Lu-10 as a protocol to clear Heat in the Lung/Large Intestine. Next it advises that in Cold associated with receding Yang Qi the Yang should be pierced twice and the Yin once but no such obvious protocol is evident for this situation. Another interpretation that would match with common practice today, based on the idea of odd numbers being Yang/moving/clearing while even numbers are Yin/tonifying/reinforcing, is that the points on the channel to be cleared are pierced on one side only while those on the channel to be tonified are pierced bilaterally.

    Ling Shu Ch. 19, on the Four Seasonal Qi, advises using the Shu-Stream points, unless the diseases are in the Fu organs, in which case the He-Sea points are chosen.

    Ling Shu Ch. 23, On Heat Diseases, recommends in cases of Heat disease accompanied with spontaneous sweating which is in accordance with the norms and further sweating is indicated removing the disease through this point, Yuji Lu-10, Dadu Sp-2 and Taibai Sp-3. Draining these points makes the Heat disappear, supplementation here makes a sweat emit. If sweating is extreme then Sanyinjiao Sp-6 ends it.

    Ling Shu Ch. 24, On Counterflow Diseases, employs the point combination mentioned in Ch. 6 for the treatment of Heart pain. It advises piercing this point and Yuji Lu-10 when treating a Heart pain that is mild on resting but increases with activity with no change in complexion, associated with the Lung.

    Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the Shu-Stream points should be pierced in summer or when the disease becomes milder and then more severe again. The seasonal aspect should not be interpreted literally as it describes the time periods of weakness and severity as "controlled by summer". It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year with afternoon corresponding to summer.

    Ling Shu Ch. 52, On the Wei Qi, considers this to be the root of the hand Taiyin meridian with the tip being at Tianfu Lu-3.


    In "opposite sword blade needling between Kongzui and Taiyuan" for cough, asthma, sore throat and hemoptysis, one needle is inserted up to 3 cun from Taiyuan Lu-9 towards Kongzui Lu-6 while another is inserted in the opposite direction from Kongzui Lu-6 to Taiyuan Lu-9. Electrical stimulation can then be applied (Liu Yan, 2008, Diagrams of Acupuncture Manipulations, p.135).

    "Lung clearing technique" is used for clearing Heat in the Lung in conditions like bronchitis (ibid, p.134).


    In pre-Ming times this point, as source point of the lung, was seen as symbolic of the air rushing down the infant's throat on its first breath and coming into contact with the world. It is therefore indicated for difficulty in relating to the physical, material world along with Renying St-9, Zhongwan Ren-12 and Tainshu St-25.
    In the Ming Dynasty this was replaced with Lieque Lu-7 as the opening points for Extraordinary Vessels was laid down.
    This set of points relates to the first Level of Manifestation of the Soul, roughly equivalent to the base or Muladhara chakra and basic consciousness, the awareness of being alive (Yuen, 2005, 3 Spirits & 7 Souls).
