    Ling Shu Ch. 19, on the Four Seasonal Qi, advises using the Shu-Stream points, unless the diseases are in the Fu organs, in which case the He-Sea points are chosen.


    In Tung acupuncture this equates to the Da Bai, Big White, point (22.04) and is often combined with Ling Gu at the other end of the bone, between the first and second metacarpals, slightly proximal to LI-4. Their location on the arm Yangming which controls Qi and Blood in the entire body together with their ability to move Qi and Blood make them applicable for most diseases (Chu, 2015).
