another name for Large Intestine channel
Hand Yang Ming
general location of Large Intestine channel
anterior lateral aspect of arm, from fingers to chest
of points on Large Intestine channel
20
where does the Large Intestine channel run?
- originates on radial side of 2nd finger (LI 1) and travels up anterior lateral aspect of arm following its pathway to the shoulder (LI 15)
- at shoulder, the channel goes to the back of the body and there is a crossing point (SI 12)
- then the channel connects / crosses with Du 14 behind the neck
- then the channel goes forward to the collarbone and descends down to its internal organ (large intestine)
- the regular channel goes up the neck + around the mouth/ nose
location of Du 14?
right below C7
why is Du 14 significant?
all Yang channels go to the back of body and connect / cross with Du 14 before going forward and descending down to its internal organ
what is a crossing point (aka intersecting point)?
how is it indicated on a chart?
- a crossing point is where a channel intersects with point son another channel (that are not points on its own channel)
- it is indicated by a triangle
which internal organs does the LI channel connect with?
Lungs + Large Intestine
what happens at the LI Luo point?
- at LI 6, the Luo / Collateral channel breaks off + travels parallel to the LI channel
- at face, the Luo / Collateral channel splits and goes into the ear + lower jaw
where do the LU and LI channels intersect?
significance?
- LI 18
- this is where the LI Divergent + LU Divergent channels go into the LU + LI internal organs
where does the LI Tendinomuscular channel (aka Sinew channel) begin?
where does it run?
- begins at LI 1 (Jing Well)
- goes up the lateral arm
- crosses to other side of head
- at shoulders, the LI Sinew channel spreads into upper thoracic vertebrae

LI 10 location
on the line joining LI 5 + LI 11: 10 up from LI 5 (or 2 cun below LI 11)
LI 11 location
when the elbow is flexed: the point is in the depression at the lateral end of the transverse cubital crease, midway between LU 5 and the lateral epicondyle of the humerus
LI 11 category
- He Sea
- also the “Master Point of Heat + Fever” (though this is not a category)
LI 12 location
when the elbow is flexed: the point is on the lateral side of the upper arm, 1 cun above LI 11, on the border of the humerus

- when the arm is abducted to just above 90 degrees, the point is in the depression appearing at the anterior border of the acromioclavicular joint
- when the arm is lowered, the point should come out in front of the acromion
