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

    Ling Shu Ch. 20, On the Five Evils, advises piercing this point, Yunmen Lu-2, Feishu Bl-13 and either Qupen St-12 or Tiantu Ren-22 (depending on how the location "in the middle of the Broken Basin" is interpreted) for pathogens in the Lung.

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

    The outer line of Tung's 12 Monkeys (Shi Er Hou) would be located slightly medial (5 fen) to this point.

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

    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).
    In the case of the lung however any number of chest points could suffice.

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

    Lad and Durve (2008) in Marma Points of Ayurveda call this point Kakshadhara or Skandadhara and associate it with Prana Vayu, Vyana Vayu, Udana Vayu, Sadhaka Pitta, Ranjaka Pitta and Avalambaka Kapha.

    They give the following functions:
    - Enhances lung capacity and flow of prana
    - Relieves tightness in chest and bronchospasm
    - Relieves pulmonary congestion
    - Relieves shoulder and arm pain
    - Pacifies aches and soreness in breasts
