Understanding Meridians in Traditional Chinese Medicine (2024)

Understanding Meridians in Traditional Chinese Medicine (1)

Meridians, or Jing Mai, defines a vessel system described in the Nei Jing (the oldest Chinese medicine book). So the word "Meridians" refers to the major longitudinal blood vessels on the body, 3 on each arm and leg, so we have a total of 12 called principal meridians. Those vessels interconnect the whole organism and transport "Qi" or blood, nutrients, and oxygen.

Traditional Chinese Medicine discovered and defined blood flow as fundamental substances flowing in the body a minimum of 1,500 years before the Europeans.

Due to the mistranslation of the Huang Di Nei Jing form Sulie de Mornat (French consul) in 1939, most Western countries people believe that Traditional Chinese medicine is based on esoteric and Energetic principles, but the reality is that it is based on strong physiology and anatomical structures knowledge, just as western medicine does.

The Significance of Meridians

经络 Jing luo or 經脈 Jing Mai are the terms used in "Yellow Eperor's Classic of Internal Medicine" (Huang Di Nei Jing), the oldest and most important book of Traditional Chinese medicine.

Jing Mai means blood vessel, and it is used in the Huang Di Nei Jing to define the blood circulation in the human body. This was written about 2200 years ago.

This meridian theory is a fundamental component of Traditional Chinese medicine.

This whole theory was developed after millennia of clinical practice, involving a deep knowledge of Yin meridians, Yang meridians, and Acupuncture points that create a circulatory system that allows us to diagnose and treat almost any imbalance in the body. Traditional Chinese Medicine TCM aims to improve the functions of the entire body through the stimulation of acupuncture meridians, herbal medicine, nutrition, qi gong, etc.

Once the body recovers its equilibrium, health comes back into our lives.

In TCM, the meridian system is the foundation of diagnosis and treatment. Practitioners believe that any disruptions or imbalances in the flow of qi through the meridians can lead to health issues and discomfort. By understanding the meridian system, TCM practitioners can identify the root causes of health problems and work to restore the balance of qi.

Traditional Chinese Medicine Theory

TCM is based on 3 foundational pillars

1- Ying-Yang and the Five Elements theory:

This is an analytic view to understand the natural laws of the Universe and the way they affect the human body. It is a way of explaining the four seasons: the day and night, the birth, life and death, etc.

We will dedicate a whole article to this topic in the future.

2- Internal Organ Theory (Zang-Fu)

Zang refers to the Heart, Kidney, Spleen, Liver, and Lung.

Fu refers to the Gallbladder, Small intestine, Stomach, Large intestine, and Urinary bladder.

The Zang-Fu organs are located inside the body, but their physiological activities and pathological changes are reflected on the exterior of the body.

So, through external observation of the face, ears, tongue, pulse, etc., a Chinese medicine practitioner can diagnose what is happening inside our bodies.

3- The Meridians and Collaterals:

a) The Meridians form a complex channel network, linking all organs in the body.

The meridians are like a highway system that interconnects the organs to each other, to the surface of the organism, and to the environment. Thanks to these acupuncture meridians, the body works as a coherent and responsive unit and allows us to adapt to our environment.

b) The Meridians are pathways that promote the circulatory system, the peripheral nervous system where blood, oxygen, and information travels all around the organism

But the major meridians not only transport elements of healthy body functions, the primary meridians also may serve as channels where external pathogens enter into the organism. The Yang meridians are the first to get affected, and then if the disease enters deeper into the body, the Yin meridians will get affected as well.

c) The Meridians are a communication system between organs and between the exterior and interior of the organism. This meridians function allows us to adapt and avoid diseases.

Traditional Chinese medicine TCM considers the channels as parts of the main organs or Zang-Fu.

All the primary meridians are connected to acupuncture points, which can be used with diagnosis or treatment procedures.

The Pathways of the Twelve Major Meridians

There are 12 primary meridians in the body: 6 Yin meridians and 6 Yang meridians, plus another eight extraordinary meridians.

Balancing Meridians for Health

TCM practitioners use various techniques to balance the flow of qi in the meridians. Acupuncture, for instance, involves inserting fine needles into specific points along the meridians to stimulate the flow of blood and promote healing through the stimulus of the nerve system. Herbal remedies, dietary changes, bodywork, and lifestyle modifications are also used to address imbalances in the meridian system.

Conclusion

Traditional Chinese Medicine has a history of almost 4,000 years.

Most of the public believes it is an energetic and esoteric discipline, but it actually is based on anatomical and physiological studies, just like Western medicine.

The Meridians are an essential part of the theory and practice of Chinese Medicine.

They are used to treat the whole body through acupuncture points, and also they are used as a diagnosis method.
