1. Meridian Theory

2. TCM notion of Meridian
A meridian is an ‘energy highway’ in the human body.
Qi (energy) flows through this meridian or energy highway, accessing all party of the body.
Meridians can be mapped throughout the body;
They flow within the body and not on the surface;
Meridians exist in corresponding pairs and each meridian has many acupuncture points along its path.

3. TCM notion of Meridian
The term ‘meridian’ describes the overall energy distribution system of Chinese Medicine and
Helps us to understand how basic substances of the body (Qi, blood and body fluids) permeate the whole body.

4. TCM notion of Meridian
The individual meridians themselves are often described as ‘channels’ or even ‘vessels’ which reflects the notion of carrying, holding, or transporting qi, blood and body fluids around the body.

5. TCM notion of Meridian
It is tempting to think of the meridians of the human body the same way as we think of the circulatory system, but here is where the similarities end.
Conventional anatomy and physiology would not be able to identify these pathways in a physical sense in the way that blood vessels can be identified.

6. TCM notion of Meridian
It is more useful to consider the meridian system as an energetic distribution network that in itself tends towards energetic manifestation.
Meridians can be best understood as a process rather than a structure.

7. TCM notion of Meridian
There are twelve main meridians, or invisible channels, throughout the body with Qi or energy flows.
Each limb is traversed by six channels, three Yin channels on the inside, and three Yang channels on the outside.
Each of the twelve regular channels corresponds to the five Yin organs, the six Yang organs as well as the Pericardium and San Jiao or Triple Warmer.

8. Composition of the Meridian System
Include 3 large groups of regular meridians正经, extra meridians奇经 and meridian divergences经别.
There are twelve regular meridians, including three yin meridians of hand手三 阴经, three yang meridians of hand手三阳经, three yin meridians of foot 足三 阴经and three yang meridians of foot足三阳经, which are collectively called “twelve meridians” or “twelve regular meridians”十二正经, and the major tracks for qi-blood circulation.
The twelve meridians have direct relationships of connection and affiliation with viscera within the body, and external-internal relationships among themselves.
The twelve meridians are the necessary passages for qi-blood circulation.

9. Composition of the Meridian System
There are 8 extra meridians, namely Ren任脉, Du督脉, Chong, Dai冲脉, Yinwei 阴维脉, Yangwei阳维脉, Yingqiao阴跷脉 and Yangqiao阳跷脉meridians, collectively called eight extra meridians奇经八脉.
They govern, communicate and regulate qi-blood within the twelve meridians, but they have no direct relationships with viscera, no external-internal relationships among themselves.
The twelve divergences are the meridians branching out from the twelve meridians.
They originate respectively from the four limbs and run through the deeper parts of the body cavity and reach up the superficial parts of the neck.

10. Composition of the Meridian System
The meridian divergences 十二经别of yang meridians branch out from their meridians and run through the body, still return to their original meridians; while the meridian divergences of yin meridians branch out from their meridians, after running through the body, they join their pairing yang meridians.
The functions of the twelve meridian divergences are mainly to strengthen the communication between the two externally-internally related meridians in the twelve meridians, they can also serve as the supplement for regular meridians by reaching some organs and components where the regular meridians do not reach.

11. Functions of the meridians
The meridians and collaterals are the major body of the meridian system, undertaking the role to circulate qi- blood and communicate so as to connect all the viscera, organs, orifices , skin, muscles tendons, bones, etc to form an integral organic whole.

12. Physiological Functions of the Meridian System
Communicate and connect all the parts of the body:
- the human body’s organic coordination and mutual relationship is accomplished through communication and connection by the meridian system；
-the twelve meridians and their branches run criss-crossly, coming and going out, ascending and descending, mutual affiliation to and connection with a pair of viscera;
- the eight extra meridians connect and communicate with the twelve regular meridians;
- the twelve meridian musculatures and the twelve skin areas connect and communicate with the skin, muscles,
- the twelve meridians link the peripheral tissues of tendons, muscles, skin, limbs and joins with the internal organs.

13. Physiological Functions of the Meridian System
For example, the hand Yangming meridians “runs by the mouth”, the foot Yangming meridians”runs by the mouth, and curves around the lips”, the hand Yangming meridian “crosses the philtrum to the site beside the opposite wing of the nose”.
In this way, it makes the interior viscera communicate with the sense organs and orifices so as to form a whole.
Each of the twelve meridians affiliates to and connects with a Zang viscus and a Fu- viscus,.
For example, the lung meridian of hand Taiyin affiliates to the lung and connects with the large intestine; and the large intestine meridian of hand Yangming affiliates to the large intestine.

14. Physiological Functions of the Meridian System
Some of the meridians, besides affiliate to and connect with special viscera, again communicate with several other viscera.
For example, the kidney meridian of foot Shaoyin not only affiliates to the kidney and connects with the bladder, but also passes through the liver, enters the lung, connects with the heart, and runs into the chest to join the pericardium.
In addition, there are also the meridian divergences that supplement the shortcomings of the regular meridians.
For example, the divergences of the foot Yangming, foot Shaoying and foot Taiyang all pass by the heart.
Thus forms multiple communications among the viscera.

15. Physiological Functions of the Meridian System
2. Conveying Qi-Blood to Nourish the Whole body:
Every viscus and tissue of the human body needs warming, nourishing and moistening by qi-blood so as to play their normal function.
Qi-blood are the material basis for life activity of the body and they must depend upon the transportation and importation by the meridian so as to distribute over the whole body for warming, nourishing and moistening all the viscera and tissues, maintaining the normal functions of the body.

16. Physiological Functions of the Meridian System
3. Reaction and Conduction
The body depends upon the meridian system to perform transmission of life information and communicate among every part.
When a part of the human body is stimulated, through the meridian system this stimulation will import into the relative viscera within the body so as to make them produce the relative changes physiologically or pathologically.

17. Physiological Functions of the Meridian System
3. Regulating Functional Balance for the Body
Where there is disharmony of qi-blood and superiority or inferiority of yin or yang in the body, the acupuncture and moxibustion therapies can be used to trigger the regulatory action of the meridian by reducing what is excessive, or reinforcing what is deficient to regulate the body and maintain the equilibrium.

18. Physiological Functions of the Meridian System
For example, when the stomach is in hypofunction, a mild stimulation given may strengthen the gastric contraction and increase the concentration of the gastric juice.
As the stomach is in a hyperactive state, a strong stimulation given will cause inhibitory effect.
Puncturing Zusanli足三里 (ST 36) point of the stomach meridian of foot Yangming can regulate the peristalic and secreting functions of the stomach.

19. The twelve meridians have lateral and symmetrical distribution on the head, face, trunk and limbs.
The six yin Meridians are distributed on the inner side of the limbs and on the inner side of the chest and abdomen.
The six yang Meridians are distributed on the outer side of the limbs and on the head, face and trunk.

20. The order and arrangement of the three yang meridians for both arms and legs are as follows;
Yang Ming (meaning bright yang or sunlight yang) has an anterior position;
Shao Yang (meaning middle yang) has a middle position;
Tai Yang (meaning greater yang) has an posterior position,
The three names have described the variations of yang qi or yang energy.
They can also be interpreted as the variations of the sunlight received.

21. The order and arrangement of the three yin meridians are as follows:
Tai Yin (meaning greater yin) has an anterior position;
Shao Yin (meaning lesser yin) has an posterior position;
Jue Yin (meaning absolute yin or terminal yin ) has a middle position
The three names have described the variations of yin qi and the degree of darkness of that position.

22. Each meridian is a Yin Yang pair, meaning each Yin organ is paired with its corresponding Yang Organ;
The Yin Lung organ, for example, corresponds with the Yang large intestine.

110. Guiding Meridian Syndrome Differentiation
For instance, in urinary retention and stress urinary incontinence resulting from diabetic cystipathy may both cause disorder of coordinative function between the detrusor urinae of bladder and spincter urethrae.
The former is caused by hyperglycemia results in injury of parasympthetic nerve dominating the detrusor urinae of bladder, leading to weak contractility of the detrusor urinae of bladder, with relative hyperactive function of sphincter urethrae; while the latter is due to laxation of pelvic floor muscles and decrease of contraction of sphincter urithrae caused by various factors, thus the function of the detrusor urinae of bladder becomes relatively hyperactive.

111. Application
of the
Meridian Theory in TCM

112. Expounding Pathological Changes
The meridians affiliate internally to the viscera, distribute externally in the body surface.
So when the body surface is invaded by the pathogens, the pathogens may go through the meridian system to go from the exterior into the interior, from the shallow to the deep, gradually transmit inward to the viscera.
Hence, the meridian system is the route for transmission of the exogenous pathogens from the skin and body surface into the viscera.

113. Expounding Pathological Changes
As an example, when cold pathogen invades the body surface, fever and aversion to cold, pain of the head and body manifested.
It is because the lung is associated with the skin and if the pathogen in the exterior cannot be expelled, it will transmit inward in to the lung and manifested cough, chest distress, chest pain and etc.

114. Expounding Pathological Changes
The lung meridian and the large intestine meridian connect with each other, so there may appear accompanying disorder of the large intestine such as abdominal pain, diarrhea or constipation.
Clinically, the meridian may be used to expound the symptoms and signs of the special sites or the corresponding sense organs and orifices in the body surface that the disorders of the five Zang-viscera and six Fu-viscera show.

115. Expounding Pathological Changes
For example, the liver meridian of foot jueyin curves round the external genitalia, descends to the lower abdomen, spreads its branches over the costal and hypochondriac region, and runs up to connect the eye connector;
So stagnation of liver qi may show pains in the hypochondria and lower abdomen;
Up-flaming of liver fire may show redness of the eyes;
Dampness-heat in the liver meridian may show scrotal wetness.

116. Expounding Pathological Changes
Mutual transmission of the visceral disorders may also be explained by the meridian theory.
The disorder of a viscus may affect the other viscus through the meridians.
For example, the liver meridian of foot Jueyin affiliates to the liver, runs by the stomach and enters the lung.
So the disorder of the liver may affect the stomach, and the fire of liver may affect the lung.

117. Expounding Pathological Changes
The kidney meridian of foot Shaoyin enters the lung and connects with the heart;
So edema due to kidney deficiency may “invade the heart” and “affect the lung”.
The spleen meridian of foot Taiyin enters the heart;
So failure of the spleen in transformation and transportation may cause deficiency of heart blood.

118. Guiding Meridian Syndrome Differentiation
Clinically one can analyze the symptoms of a disease combining with the running route and the connected viscera of a meridian so as to diagnose what meridian the syndrome associates with.
For example, a pain in the hypochondria often indicates disease of the liver and gallbladder;
A pain in the Quepen usually means disorder of the lung.

Points are the sites where qi-blood in circulation of the body gathers, and also the sites from where pathogens invade the body.
Stimulating the points may treat the diseases of the viscera and the meridians.
The meridian system is thus the passageway for medicine to play its property, and for the body to sense the stimulations from mechanical, acoustic, optic, electric and magnetic agents.
Treatment of disease by acupuncture and moxibustion is through puncturing the point or applying burning moxa over the point to smooth meridian qi so as to restore the function of the meridian in regulating visceral qi-blood of the body.

Acumoxibustion at the point may at the same time and at different levels act on normal or abnormal functions of several organs and systems.
For example, during the process of a operation under the acupuncture anesthesia, acupuncture produces analgesic effect, at the same time it can regulate the functions of the relative systems in multiple aspects, so that during the operation the blood pressure and pulsation are kept stable, and the degree of post-operative pain in the incision becomes mild, complications like infection are reduced, and the post-operative recovery gets rapid.

For instance, in urinary retention and stress urinary incontinence resulting from diabetic cystipathy may both cause disorder of coordinative function between the detrusor urinae of bladder and spincter urethrae.
The former is caused by hyperglycemia results in injury of parasympthetic nerve dominating the detrusor urinae of bladder, leading to weak contractility of the detrusor urinae of bladder, with relative hyperactive function of sphincter urethrae; while the latter is due to laxation of pelvic floor muscles and decrease of contraction of sphincter urithrae caused by various factors, thus the function of the detrusor urinae of bladder becomes relatively hyperactive.

Pharmacotherapy is also taking the meridian as the way.
Only it is through the conduction and transportation by the meridian system, can the medicine get to the focus to cure disease, playing its therapeutic effect.
Through long and repeated practice, medical scholars found the medicinal theories on for natures, five flavors, as well as ascending, descending, floating and sinking actions. This is closely related to the meridian theory.
A particular herb has a selective therapeutic effect to the illness of a certain meridian and its affiliated viscus, accordingly they founded the theory of “meridian-tropism of medicinal”.
It is a summarization of the law of medicinal treatment based on the clinical practice.
