It then descends along the medial aspect of the upper arm, and passes in tront on the Heart Channel of HandShaoyin and the Pericardium Channel of Hand-Jueyin, down to the middle portion of the elbow. From there it runs along the anterior border of the radius on the medial aspect of the forearm and goes into Cunkou, the place on the wrist over the radial arrery where the pulse is felt. Then it arrives at the thenar, runs along its border and emerges from the medial side of the tip of the thumb (Point Shaoshang, LU1l).

The branch of the channel runs directly from the proximal aspect of thewrist (Point Lieque,LU7) into the radial side of the tip of the index (PointShanhang, LU11), in which it connects with the Large Intestine Channel of HandYangming.

Location:At the radial end of the crease of the wrist ,where the pulsation of radial artery is palpable.

Indications: Indications: Cough, asthma, hemoptysis, sore throat, pain in the chest, wrist and arm.

Method: Puncture perpendicularly 0.2-0.3 inch. Avoid puncturing the radial artery. Moxibustion is applicable.
