According to the traditional Chinese description large intestine meridian is a yang channel, associated with the element metal and possesses interior and exterior relationship with the lung meridian.
Total number of points: 20.
Starting point: Tip of the radial side of the index finger.
Terminal point: Between nasolabial-groove and ala-nasi (opposite side).
Pathway: After taking origin from the starting point on the radial side of the index finger, this channel passes over the first dorsal inter-metacarpal space to reach the space bound by the tendons of the muscles extensor pollicis longus and brevis (commonly known as anatomical snuff-box). Here it crosses over the scaphoid bone and courses posterolaterally upwards to reach the lateral side of the elbow. Further, it ascends along the anterior border of the outer side of the upper arm to the shoulder joint and anterior border of acromion up to the seventh cervical vertebra. From here it runs towards supraclavicular fossa and then divides into two branches.
Branches: At the level of supraclavicular fossa, main trunk splits into a superficial branch for the face and a deep inner branch.
Superficial branch: From supraclavicular fossa it ascends up to the neck, passes over interior angle of the mandible and ascends over the upper lip to reach opposite ala-nasi to end over there. There is a crossing of the two opposite large intestine channels at the philtrum.
Inner branch: It descends down from the supraclavicular fossa to lung and from there it crosses the cardiac orifice of the diaphragm and reaches its principle organ, the large intestine.
