The Large Intestine meridian journey...
The large intestine line begins by the outside corner of the index fingernail. From there, it moves along the outside edge of the finger and between the two tendons of the thumb at the wrist joint (LI-5). It then moves across radius bone of the arm to the elbow crease.
The channel then continues on the outer shoulder to the shoulder blade where it meets with the governing vessel at the neck. It moves then internally to the lungs and large intestine. At the shoulder, a branch also travels up the anterior sides of the neck up to where it ends at the opposite nostril.
