    Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the He-Sea points should be pierced in autumn or when the disease is a result of immoderate diet. The seasonal aspect should not be interpreted literally as it describes the flavours as "controlled by autumn", probably referring to the mouth, nose and throat where the metal channels run. It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year with evening corresponding to autumn. Perhaps the most likely interpretation is during middle age, the autumn period of life, when the effects immoderate diet are likely to start to show.

    Ling Shu Ch. 71, On Evil Visitors, says that when a depletion evil is in the Lung and Heart it remains in two elbows. Yuen's theory of the Divergent meridians suggests that they store pathogens at the major joints, depleting our resources while they do, which would make this a potential point for for the Lung/Large Intestine Divergent.


    "Crossed T-Shaped Needling" involves transverse needling from Quze Lu-5 to Shaohai He-3 combined with perpendicular needling of Quchi Pc-3 for pain or paralysis of the upper limbs and heat in the upper body (Liu Yan, 2008, Diagrams of Acupuncture Manipulations, p.131).


    In five element acupuncture this point is reduced to drain excess in the Lung.


    Wang Yu-Ji often starts with this point and Yinlingquan Sp-9 as a means of harmonising the Taiyin Qi dynamic and function of fluid transformation. This is due to the Spleen governing the rising of clear Yang and the Lung governing the descent of True Qi creating a cyclical motion (Wang & Robertson, 2008, Applied Channel Theory).


    In Tung acupuncture the Qu Ling, Score Mound, point is located here, or 1.5 cun distal. It is often combined with Quchi LI-11 and used for treating a variety of Lung channel problems (Chu, 2015).


    Medieval phlebotomy point (John de Foxton, 1408: Liber Cosmographiae,; Hans von Gersdorff, 1517: Feldtbüch der Wundartzney,

    Galen (Brain, 1986, Galen on Bloodletting) also advised bleeding at the elbow for pleuritic pain (p.23) and for unrelenting nosebleed (p.84). See notes to Quze Pc-3 which seems a better location but the median cubital vein could be found here also.

    Galen also mentions the cephalic (humeral) vein and therefore this point specifically for pain in the eye and disorders of the upper neck, face and head, while the basilic vein on the inside of the elbow, near Shaohai He-3 for disorders of the lower neck (ibid.: p.91). At another point he says to bleed this point in any disorders above the level of the chest (ibid.: p.93).
