Some acupuncture points on meridians between elbow and fingertips are particularly important. Since antiquity, acupuncturists have respected them for the special actions they perform. These actions are not just local to the points themselves but affect the metabolism of the body.
The Colon channel actually goes much deeper. For instance, from its shoulder points it reaches to Governor vessel 14 at the top of the thoracic spine, and plunges down through the lungs (the Lung ‘zang‘ organ) to enter the colon (the ‘fu‘ organ) itself.
From the shoulder area a branch goes to the lower gums, to Conception vessel 24, round the mouth’s upper lip and then, via Governor vessel 26, unexpectedly crosses to the otherside of the face, ending at Colon 20 – yingxiang – beside the nose. At yingxiang it meets with the beginning of the Stomach channel – on the other side of the body from which the colon channel began.
This is the only channel to cross sides, which reflects that its ‘fu’ organ, the colon, also crosses from one side of the abdomen to the other.
Relationship with Gallbladder
In Chinese medicine the Colon ‘fu‘ works very closely with both the Lungs and the Liver to maintain smooth running of your life and immune system. For example, if there is stress and Qi Stagnation, Hegu, L.I.4 can help balance interfering or ‘over-acting’ Liver energy.
For those of us who like these ideas, there is a special relationship with the Gallbladderfu, where you can see below in the Four phase diagram, that they are opposite one another.
Although the Gallbladder channel itself doesn’t cross sides, a point on it (Gallbladder 41) has a special relationship with Dai Mai, the Girdle channel, one of the eight ‘extraordinary’ channels, which does encircle the waist, thereby crossing sides.
So, just as the Lung zang balances the Liver zang, the Colon fu balances the Gallbladder fu.
Large Intestine Luo-connecting channel
Like all the other luo channels, the Large Intestine’s luo-connecting channel is important. It commences at LI6, Pianli, joins the Lung channel in one branch, another ascending to the cheek and jaw. From here, one branch goes to the teeth, another to the ear. Pianli treats many head, face and nose problems, ranging from visual to throat problems. Mainly it treats Heat and Wind conditions, including wind-heat: these are excess yang conditions.
