4. Why the points in the small intestine channel are good at treating motor impairment diseases of the upper limb?

The small intestine channel dominants among all the channels run through the region of scapula (shoulder blade). Hence it strongly controls the muscles of the upper limb. It is particularly effective in treating pains in this region. The points of this channel are most often selected to treat motor and sensory impairments of the upper limb. As the extraordinary connection of the spleen and the small intestine, needling Shenguan (77.18), a point located in the spleen channel; and Xiajuxu (ST39) (the lower He-sea point of the small intestine channel) are very effective too. To treat the shoulder pain, Huoxi (SI3), Jienzhen (SI9) are commonly needled. Bloodletting on Shuanghe (DT.16) points on the back to treat upper limb pain is also very effective. In the two of the Shuanghe (DT.16) points, the one corresponds to the small intestine back-Shu point (BL-27) is particularly effective.

3. Why points in the stomach channel are good at treating mental diseases?

It was believed that mania is due to heat in Yangming ever since the ancient times. Mental diseases are closely related to the stomach. It is often seen that those patients with mental illness have over-active digestive power. The mania can be ameliorated if the excess syndrome of the stomach is regulated. Dian (withdrawal, depression) and Kuang (mania) can be treated by needling Fengrong (ST40) or Sihuawai (77.14), and Lidui (ST45). As for neurasthenic, tonifing the stomach to enhance the absorption of the nutrients and improve the mental functions will often cure it. To treat the neurasthenic, needling Lidui (ST45), Sihuashang (77.08) (or ST36), Fenglong (ST40) (or Sihuawai (77.14)) gives good result. Those points can be used to treat continuous nightmares. Also, the source of phlegm is the spleen and stomach, and is also related to many mental disorders. The points in the stomach channel are often used to resolve the phlegm. The same reasons apply to Ban Xia Xie Xin Tang (Pinella Heart-Draining Decoction) which is good at treating dreamy sleep and mental disorders.

1. What are the functions of the Yuan-origin points?

The distributions of the Yuan-origin points share one feature, which is they all are located distal to the wrists in the upper extremities or to the ankles in the lower extremities. The twelve Yuan-origin points are located distal to the wrist or ankle joints. They are closely related to the Yuan-origin qi of the body and are the foundations of the Zang Fu and Jing Luo (channels and collaterals). They are the points that Yuan-origin qi flows through and lingers in. The Yuan-origin points are the places where Yuan-origin qi performs its functions. The disorders of the Zang and Fu often manifest through the twelve Yuan-origin points.

In the Ling Shu, Nine Needles and Twelve Yuan-origin Points, it says “To treat the diseases of the five Zang, the twelve Yuan-origin points shall be selected.” The statement indicates that the twelve Yuan-origin points are mainly used to treat the five Zang (organ) diseases. Through the exterior-interior relationships, they are also used to treat the six Fu (bowels) diseases. One feature of the Yuan-origin points is that they not only can tonify the deficiency but also can drain the excess, a function so called “double regulating”. Hence, the Yuan-origin points not only can be used to treat the disorders of the respectively belonged or related Zang and Fu illnesses, disorders of the limbs and body trunk, but also can treat channel disorders of their respectively belonged channels. The Yuan-origin points can treat all types of disease patterns; no matter they are deficiency, excess, cold, heat, acute, chronic, or pain types. It may be said that the Yuan-origin points are the “chief points” for the disorders of their respectively belonged channel or Zang Fu.

One meaning of the Yuan is “origin”, which indicates the original qi or the moving qi between the kidneys, the so called the fundamental qi of the life. Another meaning of Yuan is a flat stretch land. As the Yuan-origin points of the Zang organs are same as their Shu-stream points and the Yuan-origin points of the Fu bowel are proximal to the Shu-stream points, where are full of vessel qi. From the perspective of Ti Ying (body correspondence theory), those are the sites abundant with flesh, and hence the Yuan-origin points govern the qi.

The applications of the Yuan-origin points are not only broad and also with high effectiveness and quick result. In the Zhen Jiao Da Cheng (The Great Compendium of Acupuncture and Moxibustion), Zhi Zheng Zuong Yao (the Generalization of Disease Treatments), the 12 Yuan-origin points are used to a high percentage of 52% in the 151 treatment songs. Based on my personal experiences and observations, the Yuan-origin points are located at the places with abundant flesh which corresponds to the Spleen and hence can tonify the acquired foundations. As the Yuan-origin points correspond to the Yuan-qi of the San Jiao and the moving qi between the kidneys, they also tonify the constitutional foundations. That is to say the Yuan-origin points can simultaneously tonify the Spleen and Kidney, and regulate both the acquired and constitutional foundations. That is why they have very wide spectrum of indications and bear very high effectiveness. Many important points of the Tung's Acupuncture are around the Yuan-origin points. For example, Huao Zhu ((66.04) ( Taichong (LV3)), Wuanshuen Er (22.09) ( Wuan Gu (SI4)), and Linggu (22.05) (Yangxi (LI5)).

8: How did Master Tung make flexible use of the Yin Yang and Wu Xing (five elements)?

There are yin and yang in a point. Differentiating a disease and selecting effective points are based on yin and yang. All creatures can be symbolized by one of the eight diagrams (Gua: divinatory symbols), which are based on yin and yang. The symptoms (descriptions) of a disease can be differentiated to yin and yang too. Selecting the treatment point in accordance with the yin and yang gives good result and better result if combining with the five-elements. For example, frozen shoulder with the symptoms “arm and shoulder unable to extend and lift”. The thinking logic would be like this: coldness governs “contraction”, hence “unable to extend” is due to coldness and the disease is water-related. Also, the arms and shoulder being heavy and difficult in lifting up belong (similarity) to damp earth, since the earth governs heavy and sinking, those damp diseases. The frozen should with the above characteristics belong to cold-damp (earth-water), and yin disease. The treatment is achieved by selecting points related to earth and water, such as Yinlingquan (SP9) (which is a water point in the earth channel). (The reason to choose the point on the spleen channel is because spleen governs the dampness and heaviness.) The point Shenguan (77.18), located very closely to Yinlingquan (SP9), can also be chosen to treat it or can be used as a Daoma point to supplement the effect. In addition, its correspondence to the neck and shoulder area in the holographic picture enables it a primary choice in this disease pattern. If the frozen shoulder is characterized with “shoulder unable to turn around”, as the shoulder is able to extend but unable to contract, it belongs to wood-tendon disorder, a yang disease. It is a wind-damp (wood-earth) disorder and can be treated by selecting points located between the Shaoyang (wood) and Yangming (earth), such as Zuwujin (77.25) and Zuqianjin (77.24). The qianjin (thousand metals) and wujin (five metals) in the point names also symbolize the heaviness. Or it can be treated effectively by needling Yanglingquan (GB34), because Yanlingquan is the earth point in the wood channel, and is one of the confluent points governing tendon. In Neijin, chapter Nine needles and Twelve source points, it says “when the disease is on the upper part of body pertaining to Fu bowel organs, select Yanglingquan (GB34),” another reason of its effectiveness.

Needling Chize (LU5) with draining technique to treat frozen shoulder is also very effective. The reasons can also be explained by the eight diagrams (xiang shu) (象 xiang: the diagrams, and 數 shu: position of strokes) and the five-elements. A disease characterized with “able to flex, but unable to extend” is well treated by Chize (LU5) (if needled by closely attaching the needle to the tendon, the Quling (33.16) point is needled in fact, the result is even better). The reasons are: 1. needling closely along the tendon to treat tendon (Quling (33.16) point of Tung's acupuncture is needled instead with this technique); 2. draining Chize (LU5) is draining the metal (Chize (LU5) is the son water point of the metal. As it is said to drain the excess, apply the draining technique on its son point), which will reduce the metal in over-controlling the wood. Once the wood is released, the shoulder will be able to lift. From the perspective of the image analogue, in accordance with the 19 bing ji (disease pathomechanisms) theory, it is said “all types of coldness and contraction”. The unable to extend implies that there is coldness and the yin is surplus. Since Chize (LU5) is located in the yin channel at the concave area, the point bears strong yin nature. Besides, Chize (LU5) is the water point, also yin nature and so draining Chize (LU5) is to drain the surplus yin. Once the surplus yin is drained, the coldness will be removed and the contraction no longer exists, and so the frozen shoulder is relieved.

Another example of making flexible use of the five elements is that Master Tung used Sima points (88.17, 88.18, and 88.19) to treat eye redness and glaucoma. The sclera (the white of eye) pertains to metal. Eye redness is analogized as “fire over-controlling metal”. Tonifying the metal will weaken the wood. Once the wood is weakened, it fails to generate the fire. Hence the fire is unable to over-control the metal. Or it may be explained as follows. Sima (88.17, 88.l8, and 88.19) points are in the stomach channel, the earth channel. Earth is the son of fire. Needling the son point will drain the fire, and hence the fire is unable to over-control the metal. As for the glaucoma, the mechanism is often due to liver wind exuberant. Tonifing the metal will put the wood under control. Or it maybe said that the Sima points are on the earth channels, needling them will course the earth and reduce the wood.

The core thoughts of Tung's acupuncture are yin yang and the five elements. The inter-promotion and inter-restraint of the five-elements in the Tung's acupuncture is actually secondary important. The most important is the Tong Tou (Tong Gen and Tou Zhi) and Liu Zhuan (flow and transform). Some points give better results when the patients are needled with lying position; while some others needle with sitting or standing position. This is related to the ascending, descending, opening, closing, storing or flowing of the yin yang and qi blood.

7: Does every acupuncture point have its own combination of yin and yang and five elements?

This is a very good question. I asked the same question to Master Tung back in the old times. I grasp the answer through the practice of the Tung's acupuncture. Every herb has its very particular nature (four natures) and flavor (five flavors). The four natures, cold-hot-warm-cool, correspond to the yin and yang; and the five flavors (sour-bitter-sweet-pungent-salty) correspond to the five elements. A human body resembles a small cosmos. Certainly every point, under the Tung's acupuncture or the 14 channel system, in our body has its particular combination of yin and yang and five elements. A point's yin and yang is related to the point's location including those aspects: five tissues, five transport points, and channels and collaterals. For example, the muscle bulge area pertains to yang, and hence the names of the points often contain the words such as mountain, mound, village, and seas (山陵里海). The main function of those points is to regulate qi. Points such as the Sima points (88.17, 88.18, 88.19), Shousanli (LI10), and Jienzhong (44.06) all carry the function of regulating qi. The concave of a muscle pertains to yin, and hence the names of the points often contain the words such as ditch, brook, swamp and ravine (溝溪澤谷). The main function of those points is to regulate the blood. For example, Neiguan (PC6) and Huozhu (66.04) points, etc. A point's yin and yang combination also is related to its five-transport and five-elements. The point's yin and yang combination is also based on its five element natures, metal, water, wood, fire and earth. It is also related to its channel's yin and yang nature, for example yin within yin, yin within yang, yang within yang and yang within yin. All those form the moving directions of a point to ascend, descend, exit and enter. The applications of the points are hence very flexible.

Certainly every point has its five-element nature. The five-elements of the five transport points are well known. I certainly do not need to give examples. For other points, their five element nature is related to its belonging channel, organ, and five tissues. For example, if a point's tissue is attaching to a bone, then its nature bears water property; if it is attaching to a tendon, then its nature bears wood nature. Those Tung's points on the back region related to the organs and bowels such as Wuling (DT04), Shuangfong( DT.05), Jiohuo (DT.06), Sanjin (DT.07), Jingzhi (DT08), Jinlin (DT.09), Dingzhu (DT.10), Huoxin (DT.11), indicate their five element nature in their own names. Their names are given according to their surrounding organs or bowels.
