    Notes:
    Ling Shu Ch. 5 places this point, called Tai Cang as the end of Taiyin with Yin Bai Sp-1 as the root. In cases of "barrier and flushing" (being unable to receive food and undigested food flowing out, trans: Unschuld, 2016) the whole channel is to be examined for surplus and deficiency and the pathology removed.

    Ling Shu Ch. 68, On an Upper Barrier (causing vomiting after eating), suggests a technique to deal with an obstruction of the lower stomach duct caused by Cold entering the Stomach leading to accumulation, obstruction, stagnation and pain with heat on the skin above. An accumulation within the duct provokes a pain at depth, one outside the duct causes pain at the surface. This point is not mentioned by name but it would be in this approximate location. The obstruction is found by palpation and pressed to ascertain its strength and depth. It is then needled superficially to the side and inserted deeper to the level of the obstruction up to three times. Afterwards a hot compress is applied. This treatment is to be repeated daily while the patient observes dietary regulations and cultivates a tranquil state of mind so that the Qi moves again. Then they ingest salty (or sour according to Huangfu Mi's Jia Yi Jing) and bitter medicines and will be able to eat again.

    Yuen (2005, The Eight Extraordinary Vessels) considers this to be the origin of the Lung meridian and the Primary Channels.
    He also states that, according to the Ling Shu theory that the Leg Yin channels terminate and concentrate their Qi on the central axis of the body, it is also the Termination point of the Spleen, to be used in cases of Spleen Yin Stasis.

    This point, as origin of the Lung channel and front Mu of the Stomach, is seen as symbolic of the switch to post-natal nourishment from the lungs and stomach after the infant's first breath instead of through the navel at Shenque Ren-8 pre-natally.
    It is therefore indicated for difficulty in relating to the physical, material world along with Renying St-9, Lieque Lu-7 or Taiyuan Lu-9 and Tainshu St-25.
    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).

    The Front Mu points make likely locations for application of leeches to reduce fevers according to François Broussais' (1772–1838) philosophy who believed in placing them over the diseased organs to reduce inflammation (Greenstone, 2010, The history of bloodletting, BCMJ, Vol. 52, No. 1, Pp 12-14).
