    In Master Tung's system this point is one of the five mountain ranges (Wu Ling). They consist of five sets of points in three lines representing the phases of the Wu Xing in a series of lines:

    The first set is along the midline, below each vertebrae from T2 to T11. From T2 to T8 relate to Fire, T9 to T11 relate to Earth.
    The second set is 3 cun from the midline. from T2 to T9. From T2 to T6 relate to Metal, T7 to T9 relate to Wood.
    The third set is 6 cun from the midline from T2 to T8. From T2 to T4 relate to Metal, T5 to T8 relate to Wood.

    They are indicated for fever, common cold, hypertension, headache, lumbar pain, numbness of the hands and feet, hemiplegia, acute stomachache, vomiting or acute enteritis by releasing heat, wind and stagnation from the organs relating to their phase and treated with a pricking method to release a drop of blood (McCann, 2014, Pricking the Vessels).

    This sort of technique may make greater sense than regular needles as shallow depth without retention may be safer over the spine and lungs.

    In Tibetan medicine:
    Edelweiss flowers are burnt in cones like moxa over crushed garlic at this point as a spleen point to relieve gas formation, heaviness of the body and heavy sleep (Bradley, 2000: Principles of Tibetan Medicine)
