Location
On the ventral aspect of the wrist, at the level of the wrist joint space (most distal wrist crease), on the radial aspect of the radial artery, and ulnar to the tendon of the abductor pollicis longus muscle.
How to find
As the location of the wrist crease varies, the ventral joint space (➞ 3.3.3) between the proximal row of carpals and the radius/ulna is a more reliable landmark for orientation. By loosely moving the hand, the joint space is easily palpable. Palpate the radial artery (pulsation) on the radial side and locate LU-9 on its radial aspect. Located on the same level are ➞ P-7 (between two tendons) and ➞ HE-7 (radial to the insertion of the tendon of the flexor carpi ulnaris on the pisiform bone).
Needling
Vertically 0.2–0.5 cun. Caution: Avoid radial artery. If the needle pulsates (the desired effect), there is no additional stimulation!
Actions/Indications
● Strengthens the Lung, transforms Phlegm, descends the Lung Qi
● Regulates and harmonizes the vessels (relationship between zong qi and Blood circulation)
● Opens the channel, alleviates pain
Special features
Yuan-source point, shu-stream point, Earth point, notification point, and hui-meeting point of the vessels. The important point for toni-fying the Lung Qi and Yin, especially with chronic disorders.
