OVERVIEW: The Small Intestine Meridian of the Hand Tai Yang belongs to the Fire phase, and is interiorly-exteriorly coupled with the Heart Meridian of the Hand Shao Yin and paired with the Urinary Bladder Meridian of the Foot Tai Yang according to Six Channel Theory. Even though the principal function of the Small Intestine is to receive, transform and separate fluids, the only indications for points on the meridian relating to this function are dark and hesitant urination. Moreover, despite the fact that the meridian connects with the diaphragm and Stomach, passes through the Conception Vessel at CV 12 and CV 13, and descends to the Small Intestine, no points of the Small Intestine Meridian are indicated for disorders of the digestive system. Rather, as a Fire meridian, its links with the Heart and Urinary Bladder channels, and the pathways of its primary and secondary pathways, the points of the Small Intestine Meridian are used for clearing heat from the pathways of the meridian and reducing fever, especially malarial fever, assisting in transforming phlegm and clearing heat from the Heart (ie mania disorder), cooling heat and fire and alleviating pain along the course of the meridian in the arm, axilla, shoulder, scapula, neck (including mumps) and throat, jaw, mouth, teeth, tongue, nose, cheek, eyes and ears, and treating disorders of the breast and lateral costal region. Points of the Small Intestine Meridian are also particularly indicated for swelling (mainly of the neck, throat and cheek).
PRIMARY PATHWAY: 1. Originates at the ulnar side of the tip of the little finger at SI1; 2. Ascends along the ulnar side of the hand and emerges at the styloid process of the ulna at SI6; 3. Follows the ulna to the medial aspect of the elbow; 4. Runs along the posterior aspect of the upper arm; 5. Zig-zags from the inferior fossa to the superior fossa of the scapula through SI11 and SI12, and then to the medial aspect of scapular spine at SI13; 6. Crosses via SI14 and SI15 to the lower border of the spinious process of C7; 7. Descends into the supraclavicular fossa and connects with the Heart; 8. Descends along the oesaphagus and passes through the diaphragm to the Stomach; 9. Enters the Small Intestine; 10. A branch ascends from the supraclavicular fossa to cross the neck and cheek to the outer canthus of the eye, then travels posteriorly to the ear and enters the ear at SI19; 11. Another branch separates on the cheek at SI18 to the inner canthus of the eye; 12. Another branch descends to the lower he-sea point of the Small Intestine at ST39.
LUO-CONNECTING PATHWAY: Separates from the Small Intestine channel at SI7 and connects with the Heart channel, ascends along the arm and connects with the shoulder at LI15.
DIVERGENT PATHWAYS: Diverges from the primary Small Intestine channel at the shoulder, enters the axilla, crosses the Heart and descends to the abdomen where it connects with the Small Intestine.
