Large intestine meridian (hand Yang brightness) Pathway

Large intestine meridian

The large intestine is called the 'Minister of Transportation'. It controls the transformation of digestive wastes from liquid to solid state and transports the solids onwards and outwards for excretion through the rectum. It plays a major role in the balance and purity of bodily fluids and assists the lungs in controlling the skin's pores and perspiration.

Coupled with the lungs by Metal energy, the large intestine depends on the lungs for movement via the expansion and contraction of the diaphragm, which works like a pump to give impetus to peristalsis by regulating abdominal pressure. Thus sluggish bowels may be stimulated and constipation cured by deep diaphragmic breathing and by tonifying lung energy. Conversely, congested lungs and clogged bronchial passages may be cleared by purging the bowels.

Passage with points

The meridian starts from the tip of the index finger (LI 1)  runs upward along the radial side of the index finger  passes through the interspace of the 1st and 2nd metacarpal bones  dips into the depression between the tendons of extensor pollicis longus and brevis muscles  then follows the anterior border of the lateral aspect of the forearm  reaches the elbow  from there ascends along the anterior border of the lateral aspect of the arm to the highest point of the shoulder  along the anterior border of the acromion goes up to the 7th cervical vertebra (Du 14)  descends to the supraclavicular fossa  the branch from there runs upward to the neck  passes through the cheek  enters the gums of the lower teeth  curves around the upper lip  crosses the opposite meridian at the philtrum  ends at the lateral side of the nose (LI 20), where it links with the stomach meridian.

Passage without points

The branch from the supraclavicular fossa goes down to connect with the lung  passes through the diaphragm  enters its pertaining organ the large intestine.

Pathway:

The hand Yang brightness (Yangming) large intestine meridian begins at the radial side of the tip of the index finger. It proceeds upward between the first and second metacarpal bones of the hand and between the tendons of the extensor pollicis longus and brevis muscles at the wrist. It continues along the radial margin of the forearm to the radial margin of the lateral aspect of the elbow, then up the lateral aspect of the upper arm and over the shoulder joint. After intersecting the hand greater Yang (Taiyang) meridian at SI-12 (Grasping the Wind), it rises to just below the spinous process of the seventh cervical vertebra and intersects with the governing vessel at GV-14 (Great Hammer) where all six yang meridians meet. It then travels straight into the supraclavicular fossa to ST-12 (Empty Basin) from where it nets the lung, passes through the diaphragm, and homes to the large intestine. A branch separates from the main meridian at ST-12 (Empty Basin) in the supraclavicular fossa, passes up the neck, and traverses the cheek before entering the lower gum. From here it skirts around the lips, passes the foot Yang brightness (Yangming) meridian at ST-4 (Earth Granary), and then meets the same meridian coming from the other side of the body at the philtrum. It then continues around the nostril of the opposite side to terminate at the side of the nose. In other words, right and left meridians cross over at the philtrum and run for the last short stretch on the opposite side of the body from which they originated. The Canon of Medicine describes yet another branch that separates from the main meridian at ST-12 (Empty Basin), descends past ST-13 (Qi Door) and penetrates the lung, passes through the diaphragm, homes to the large intestine, and descends to the lower limb to emerge at ST-37 (Upper Great Hollow), which is the lower uniting point of the large intestine.
