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

    Ling Shu Ch. 6 suggests piercing the Ying points (and Shu points according to Unschuld, 2016, but not according to Wu & Wu, 201) of the Yin channels if a disease is in the Yin of the Yin realm (e.g. the Zang organs) suggesting this point (and Taibai Sp-3) in diseases of the Spleen.

    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, Taibai Sp-3 and Zusanli St-36 as a protocol to clear Heat in the Stomach/Spleen. 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 opening the Jing-Well and Ying-Spring openings in winter, piercing deeply and retaining the needle for a while.

    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, Taiyuan Lu-9, Yuji Lu-10 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 Taibai Sp-3 when treating a severe Heart pain accompanied by distended abdomen and fullness in the chest, associated with the Stomach.

    Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the Ying-Spring points should be pierced in spring or when the disease is associated with a change in complexion. The seasonal aspect should not be interpreted literally as it describes the colours as "controlled by spring". It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year with morning corresponding to spring.
