Differential diagnosis (Zhen Duan) is a central concept in traditional Chinese medicine (TCM) theory. In clinical practice it is the process of identifying the specific pattern of disharmony or imbalance that is causing a patient’s symptoms and determining the appropriate treatment.
In TCM, the body is seen as a complex system of interconnected functions and processes that are in balance when the person is healthy. When there is an imbalance, the body experiences symptoms and signs that reflect the nature and severity of the disharmony.
Differential diagnosis involves a thorough evaluation of the patient’s symptoms and signs, including their physical, emotional, and mental states, as well as their pulse and tongue. The TCM practitioner will consider the patient’s age, gender, constitution, and other factors that may be relevant to the diagnosis.
The TCM practitioner will use this information to identify the pattern of disharmony and determine the appropriate treatment. This may include acupuncture, herbal medicine, dietary recommendations, and other therapies.
Differential diagnosis is an integral part of the TCM clinical process, and it requires a deep understanding of TCM theory and a skilled and experienced practitioner to correctly diagnose and treat the patient.

Pattern/Syndrome Differentiation
In traditional Chinese medicine (TCM), pattern/syndrome differentiation refers to the process of identifying patterns of imbalance or disharmony in the body and developing a treatment plan to restore balance and promote health. TCM practitioners use a variety of diagnostic tools and frameworks, such as the eight principles (Ba Gang), organs (Zang Fu), meridians/channels (Jing Luo), six stages (Liu Jing), four levels (Wei, Qi, Ying, Xue), five elements (Wu Xing), Qi, blood, and body fluids (Qi, Xue, Jin Ye), and the triple burner (San Jiao), to identify patterns of imbalance or disharmony in the body and to develop a treatment plan to restore balance and promote health.
The goal of pattern/syndrome differentiation in TCM is to identify the root cause of a patient’s condition or imbalance and to treat the whole person, rather than just the symptoms. TCM practitioners may use a variety of treatment modalities, such as acupuncture, herbal medicine, and dietary and lifestyle recommendations, to restore balance and promote health in the body.
Eight Principles (Ba Gang)
The eight principles (Ba Gang) in traditional Chinese medicine (TCM) are a set of diagnostic categories that practitioners use to classify patterns of disharmony or imbalance in the body. These principles are:
- Yin and yang: This principle refers to the balance of two opposing and complementary forces in the body. In TCM, yin represents the feminine, passive, and receptive aspects of the body, while yang represents the masculine, active, and expressive aspects.
- Interior and exterior: This principle refers to the location of an imbalance or condition within the body. An interior condition is one that affects the internal organs, while an exterior condition affects the surface of the body.
- Cold and heat: This principle refers to the presence of excess or deficiency of either cold or heat in the body. In TCM, cold is thought to constrict and contract the body, while heat expands and stimulates it.
- Deficiency and excess: This principle refers to the presence of either a deficiency or excess of certain substances in the body, such as Qi (vital energy), blood, or fluids.
- Full and empty: This principle refers to the presence of either excess or deficiency of certain substances in the body. A full condition is one in which there is an excess of substances, while an empty condition is one in which there is a deficiency.
- Qi and blood stagnation: This principle refers to the proper flow of Qi (vital energy) and blood in the body. Stagnation refers to a blockage or disruption in the flow of these substances, which can lead to various health issues.
- Upward and downward: This principle refers to the movement of Qi (vital energy) and other substances in the body. An upward movement refers to the upward movement of substances, while a downward movement refers to the downward movement.
- Excess and deficiency of organ systems: This principle refers to the balance of function between the various organ systems in the body. An excess or deficiency of function in one or more organ systems may indicate an imbalance or disharmony in the body.

Organs (Zang Fu)
Zang Fu is a foundational concept in Traditional Chinese Medicine (TCM) that refers to the internal organs and their functions in the body. The term is split into two categories: Zang (yin organs) and Fu (yang organs). Each organ is associated with specific physiological functions, emotional aspects, and their interactions with the other organs. Together, the Zang Fu organs create a dynamic system that maintains the body’s balance, health, and well-being.
The Zang Organs (Yin Organs)
The Zang organs are considered solid and are responsible for producing, storing, and regulating the body’s vital substances, such as Qi, Blood, Fluids, and Essence. The five Zang organs include:
- Heart (Xin) – Governs Blood and houses the Shen (mind/spirit). It controls mental activities, emotions, and consciousness.
- Liver (Gan) – Stores Blood and ensures the smooth flow of Qi. It regulates emotions, and its balanced function supports clear decision-making and emotional flexibility.
- Spleen (Pi) – Governs transformation and transportation of food and fluids into Qi and Blood. It supports digestion and the production of Qi and Blood, contributing to muscle tone and mental clarity.
- Lung (Fei) – Governs Qi and respiration. It regulates the skin and immune function, and its proper function supports the body’s defense against external pathogens.
- Kidney (Shen) – Stores Essence (Jing) and governs reproduction, growth, and aging. It is also responsible for water metabolism and regulating bones and marrow.
The Fu Organs (Yang Organs)
The Fu organs are hollow and primarily involved in transforming and transporting food, waste, and fluids. They are closely tied to the Zang organs but operate more on a process-oriented basis. The six Fu organs include:
- Stomach (Wei) – Responsible for receiving and digesting food. It is known as the “Sea of Food and Fluids” and transforms nutrients for further processing.
- Small Intestine (Xiao Chang) – Separates the clear from the turbid, i.e., absorbs nutrients and sends waste downward.
- Large Intestine (Da Chang) – Absorbs water and eliminates waste.
- Gallbladder (Dan) – Stores and excretes bile, aiding digestion. It also influences decision-making and courage.
- Urinary Bladder (Pang Guang) – Stores and excretes urine.
- Triple Burner (San Jiao) – Governs the regulation of water passages and is not a physical organ but a system that coordinates Qi circulation and metabolism through the upper, middle, and lower parts of the body.
The Zang Fu Relationship
The Zang and Fu organs do not function independently; they are interconnected through mutual relationships that help balance the body. For example:
- The Lung (Zang) governs Qi, but its function depends on the Large Intestine (Fu) to eliminate waste and maintain the purity of Qi circulation.
- The Spleen (Zang) transforms nutrients, but its relationship with the Stomach (Fu) ensures food is digested properly.
- The Heart (Zang) governs Blood circulation, while the Small Intestine (Fu) assists in separating nutrients to ensure the body has sufficient material to produce Blood.
These organ pairs also operate through Five Element theory, where organs are linked through cycles of generation and control (Wood, Fire, Earth, Metal, Water), affecting one another’s health and function.
Clinical Application of Zang Fu Theory
In TCM diagnosis and treatment, the Zang Fu theory plays a central role in identifying patterns of disharmony within the body. Practitioners use this framework to understand the underlying imbalances causing symptoms and to prescribe appropriate treatments. Some examples of clinical application include:
- Pattern Differentiation: Identifying which Zang or Fu organs are imbalanced based on symptoms such as fatigue, insomnia, digestive issues, emotional disturbances, or pain. For instance:
- Heart Qi Deficiency: Symptoms might include palpitations, shortness of breath, and insomnia.
- Liver Qi Stagnation: Symptoms may include emotional frustration, mood swings, and hypochondriac pain.
- Spleen Qi Deficiency: Symptoms can manifest as poor appetite, bloating, loose stools, and fatigue.
- Herbal Medicine: Herbal formulas are often prescribed based on the Zang Fu organs involved in the condition. For example:
- Gui Pi Tang (Restore the Spleen Decoction) may be used for Spleen Qi deficiency with accompanying Heart Blood deficiency, manifesting as fatigue, anxiety, and insomnia.
- Xiao Yao San (Rambling Powder) is commonly used to treat Liver Qi stagnation, especially when there are symptoms of emotional tension and digestive issues.
- Acupuncture: Acupuncture treatments are designed to regulate the flow of Qi between the Zang Fu organs. For example:
- The Liver governs the smooth flow of Qi, so acupuncture points on the Liver meridian may be used to relieve Liver Qi stagnation.
- In the case of Lung Qi deficiency, acupuncture points such as Lung 9 (Taiyuan) might be selected to tonify Lung Qi and improve respiratory function.
- Lifestyle and Dietary Adjustments: Patients may be advised on lifestyle changes that align with their Zang Fu diagnosis. For example:
- A patient with Spleen Qi deficiency may be advised to eat warm, nourishing foods like soups and stews to support digestion.
- A patient with Liver Qi stagnation may be encouraged to incorporate activities that promote emotional release, such as Qi Gong or regular exercise.
- Emotional Health: Each Zang organ is associated with a specific emotion, and emotional imbalances can impact the corresponding Zang organ. For example:
- Excessive anger is tied to the Liver and can lead to Liver Qi stagnation.
- Excessive worry can weaken the Spleen, leading to poor digestion and fatigue. Understanding the emotional-physical connection is essential for treating both mental and physical health issues in TCM.
Zang Fu theory provides a holistic and interconnected approach to diagnosing and treating health conditions. By focusing on the organ systems’ physiological, emotional, and energetic functions, TCM practitioners can identify underlying imbalances and offer individualized treatments that restore harmony in the body. Whether through herbal medicine, acupuncture, or lifestyle recommendations, Zang Fu theory remains one of the core frameworks for clinical practice in Traditional Chinese Medicine.

Meridian/Channel (Jing Luo)
In Traditional Chinese Medicine (TCM), the concept of pattern/syndrome differentiation using meridian/channel (Jing Luo) theory is essential for diagnosing and treating imbalances or conditions in the body. Meridians and channels are believed to be pathways through which Qi (vital energy), Blood, and Fluids flow, connecting the internal organs (Zang Fu) and influencing the body’s overall balance and health.
TCM practitioners use Jing Luo theory to assess the flow of Qi and Blood through the body’s 12 main meridians. This allows them to identify patterns of disharmony and develop treatment plans to restore health and promote balance. In clinical practice, the assessment involves examining the patient’s symptoms, observing the body, taking a detailed medical history, and identifying any meridian imbalances that may be contributing to the patient’s condition. Common treatment modalities such as acupuncture, herbal medicine, and dietary and lifestyle recommendations target specific meridians to regulate the flow of Qi and Blood.
The 12 Main Meridians (Jing Luo) and Clinical Applications
Each meridian corresponds to a particular Zang or Fu organ, and disharmonies within these meridians can manifest as specific symptoms or imbalances. Below is a description of the 12 main meridians and their roles in maintaining health, along with their clinical significance and applications.

Integrating Meridian Theory in Clinical Practice
In TCM, meridian theory serves as the backbone of diagnosis and treatment. By understanding the flow of Qi through the Jing Luo system and the associated organ functions, practitioners can pinpoint the root causes of disease. Treatments are designed to harmonize the flow of Qi and Blood within the meridian system, addressing both the physical and emotional aspects of health.
Acupuncture is often used to stimulate specific points along these meridians, while herbal medicine and lifestyle modifications are prescribed to support the flow of Qi and strengthen weakened organ systems. For example, a patient with Liver Qi stagnation may receive acupuncture along the Liver meridian to promote free-flowing Qi, and herbal formulas may be prescribed to further support this balance. Likewise, dietary recommendations may focus on reducing stress and avoiding food that generates Damp-Heat, such as greasy or spicy foods.
This holistic approach allows TCM practitioners to restore the balance of Qi, Blood, and Jing (Essence) through the meridians, ultimately promoting physical and emotional well-being.

Six Stages (Liu Jing)
The Six Stages (Liu Jing) theory in Traditional Chinese Medicine (TCM) is a diagnostic framework used to understand the progression of disease caused by external pathogens, particularly cold. This theory, which originates from the classical text “Shang Han Lun,” describes how illness moves through the body’s energetic layers from the most superficial to the deepest levels. Each stage is associated with a specific set of symptoms and treatment strategies aimed at restoring balance and health.
The six stages are divided into three Yang stages and three Yin stages, representing the body’s external and internal defenses, respectively:
- Taiyang (Greater Yang)
- Description: This is the most superficial stage and represents the body’s first defense against external pathogens, often cold and wind. The Taiyang stage affects the Bladder and Small Intestine meridians.
- Symptoms: Chills, mild fever, aversion to cold, headache, stiff neck, and possibly sweating.
- Treatment: Focuses on releasing the pathogen from the surface through sweating and dispersing wind-cold using herbs such as Ma Huang Tang or acupuncture points along the Bladder and Small Intestine meridians.
- Yangming (Bright Yang)
- Description: This stage occurs when the pathogen has penetrated deeper, affecting the Stomach and Large Intestine meridians. It is characterized by an abundance of heat.
- Symptoms: High fever, profuse sweating, extreme thirst, a red face, irritability, and a strong pulse.
- Treatment: Clearing heat and draining fire through methods such as cooling herbs like Bai Hu Tang or acupuncture points that help eliminate excess heat.
- Shaoyang (Lesser Yang)
- Description: This is an intermediate stage where the pathogen oscillates between the external and internal layers of the body, affecting the Gallbladder and Triple Burner meridians.
- Symptoms: Alternating chills and fever, bitter taste in the mouth, dry throat, nausea, irritability, and fullness in the chest.
- Treatment: Harmonizing the interior and exterior by using herbs such as Xiao Chai Hu Tang and acupuncture points along the Shaoyang channels.
- Taiyin (Greater Yin)
- Description: When the disease penetrates deeper, it affects the body’s internal organs, particularly the Spleen and Lungs, leading to cold and deficiency.
- Symptoms: Abdominal fullness, poor appetite, diarrhea, fatigue, and a pale complexion.
- Treatment: Warming and tonifying the Spleen and Lung to support digestion and energy production, using formulas like Li Zhong Wan or acupuncture points to strengthen the digestive system.
- Shaoyin (Lesser Yin)
- Description: This stage reflects a deeper imbalance between the Heart and Kidney organs, where either cold or heat can dominate, leading to deficient Yin or Yang.
- Symptoms (Cold): Cold limbs, fatigue, aversion to cold, desire to sleep, weak pulse.
Symptoms (Heat): Irritability, insomnia, dry mouth, dark urine. - Treatment: In the cold type, warming and nourishing Yang using Si Ni Tang is recommended, while in the heat type, cooling and nourishing Yin with Huang Lian E Jiao Tang is used.
- Jueyin (Terminal Yin)
- Description: This is the final and deepest stage, often involving extremes of heat and cold. It affects the Liver and Pericardium meridians and can manifest as a combination of both deficiency and excess.
- Symptoms: Sensation of heat in the upper body and cold in the lower body, thirst, hunger without desire to eat, vomiting, diarrhea, and weakness.
- Treatment: Restoring balance between Yin and Yang, focusing on harmonizing the extremes with herbs like Wu Mei Wan or acupuncture that regulates the Liver and Pericardium meridians.
Integrating the Six Stages with Other TCM Theories
The Six Stages are used alongside other foundational frameworks, such as the Four Levels (Wei, Qi, Ying, Xue), which offer a similar understanding of disease progression, but from the perspective of internal imbalances rather than external attacks. TCM also considers Zang Fu theory, focusing on the function of internal organs and their relationships.
Practitioners may combine the Six Stages with Eight Principles (Ba Gang), which categorize conditions by internal/external, cold/heat, excess/deficiency, and Yin/Yang. Together, these diagnostic tools create a comprehensive understanding of the patient’s condition, allowing for highly individualized treatments.
The Six Stages (Liu Jing) represent a vital diagnostic framework in Traditional Chinese Medicine, guiding practitioners in understanding the progression of disease and its treatment. By integrating the Six Stages with other TCM principles like the Eight Principles, Zang Fu theory, and meridian channels, practitioners can precisely identify patterns of imbalance and offer tailored treatments that address both the root and symptoms of illness. This holistic, multi-layered approach defines TCM’s strength in addressing complex and chronic health conditions.
The application of these principles is deeply embedded in Yo San University’s Master’s and Doctoral Degree Programs, where students learn to apply these theories in both classroom and clinical settings, developing the expertise necessary to restore health and balance in their patients.
Four Levels (Wei, Qi, Ying, Xue)
The four levels (Wei, Qi, Ying, Xue) theory in traditional Chinese medicine (TCM) is a diagnostic framework that practitioners use to identify patterns of imbalance or disharmony in the body and to develop a treatment plan to restore balance and promote health. In TCM, the four levels refer to four different layers or levels of the body, and each level is associated with a specific set of symptoms and treatment principles.
The four levels are:
- Wei (defensive) level: The Wei level is the outermost layer of the body and is responsible for protecting the body from external pathogens and toxins. Symptoms of imbalance at the Wei level may include fever, chills, and joint pain. Treatment for the Wei level involves the use of warming and tonifying herbs and acupuncture points to strengthen the body’s resistance to external pathogens.
- Qi (vital energy) level: The Qi level is the second layer of the body and is responsible for the production and circulation of Qi (vital energy) throughout the body. Symptoms of imbalance at the Qi level may include fatigue, shortness of breath, and digestive issues. Treatment for the Qi level involves the use of herbs and acupuncture points to tonify and regulate Qi (vital energy) in the body.
- Ying (nutritive) level: The Ying level is the third layer of the body and is responsible for the nourishment and support of the body’s tissues and organs. Symptoms of imbalance at the Ying level may include weakness, anemia, and poor appetite. Treatment for the Ying level involves the use of nourishing and tonifying herbs and acupuncture points to support and nourish the body’s tissues and organs.
- Xue (blood) level: The Xue level is the innermost layer of the body and is responsible for the circulation of blood throughout the body. Symptoms of imbalance at the Xue level may include irregular menstruation, blood disorders, and blood stasis. Treatment for the Xue level involves the use of herbs and acupuncture points to regulate and nourish the blood and promote circulation.

Five Elements (Wu Xing)
The five elements (Wu Xing) theory in traditional Chinese medicine (TCM) is a diagnostic framework that practitioners use to identify patterns of imbalance or disharmony in the body and to develop a treatment plan to restore balance and promote health. In TCM, the five elements refer to five different aspects or qualities that are believed to be present in all living things and to influence the functioning of the body.
The five elements are:
- Wood: The wood element is associated with the liver and gallbladder, and it is believed to be responsible for the smooth flow of Qi (vital energy) and the regulation of emotion. Symptoms of imbalance in the wood element may include anger, frustration, and irritability. Treatment for the wood element involves the use of calming and nourishing herbs and acupuncture points to support the liver and gallbladder and promote the smooth flow of Qi (vital energy).
- Fire: The fire element is associated with the heart and small intestine, and it is believed to be responsible for the circulation of blood and the expression of emotion. Symptoms of imbalance in the fire element may include anxiety, insomnia, and heart palpitations. Treatment for the fire element involves the use of calming and nourishing herbs and acupuncture points to support the heart and small intestine and promote the circulation of blood.
- Earth: The earth element is associated with the spleen and stomach, and it is believed to be responsible for the transformation and transportation of nutrients in the body. Symptoms of imbalance in the earth element may include poor appetite, bloating, and indigestion. Treatment for the earth element involves the use of nourishing and tonifying herbs and acupuncture points to support the spleen and stomach and promote the transformation and transportation of nutrients in the body.
- Metal: The metal element is associated with the lung and large intestine, and it is believed to be responsible for the regulation of the body’s water metabolism and the elimination of waste. Symptoms of imbalance in the metal element may include respiratory issues, constipation, and dryness. Treatment for the metal element involves the use of moistening and nourishing herbs and acupuncture points to support the lung and large intestine and promote the regulation of the body’s water metabolism and the elimination of waste.
- Water: The water element is associated with the kidney and bladder, and it is believed to be responsible for the production of Qi (vital energy) and the regulation of water metabolism in the body. Symptoms of imbalance in the water element may include fatigue, low back pain, and urinary issues. Treatment for the water element involves the use of tonifying and nourishing herbs and acupuncture points to support the kidney and bladder and promote the production of Qi (vital energy) and the regulation of water metabolism in the body.
TCM practitioners use the five elements theory in combination with other diagnostic tools to develop a treatment plan to restore balance and promote health.

Qi, Blood, Body Fluids (Qi, Xue, Jin Ye)
In traditional Chinese medicine (TCM), the concept of pattern/syndrome differentiation using Qi, blood, and body fluids (Qi, Xue, Jin Ye) refers to the use of the body’s vital substances to diagnose and treat imbalances or conditions. TCM practitioners view Qi (vital energy), blood, and body fluids as essential substances that are necessary for maintaining health and balance in the body.
TCM practitioners use the concept of Qi, blood, and body fluids to identify patterns of imbalance or disharmony in the body and to develop a treatment plan to restore balance and promote health. To do this, practitioners may assess the patient’s symptoms, observe the body, and take a detailed medical history to gather information about the patient’s overall health and any imbalances or conditions present.
There are three main substances in TCM that are believed to be the most important for maintaining health and balance in the body:
- Qi (vital energy): Qi is the vital energy that is believed to circulate throughout the body and to be necessary for the proper functioning of the body’s organs and systems. Symptoms of Qi imbalances may include fatigue, shortness of breath, and digestive issues. Treatment for Qi imbalances may involve the use of herbs and acupuncture points to tonify and regulate Qi (vital energy) in the body.
- Blood: Blood is the vital substance that is believed to nourish and support the body’s tissues and organs. Symptoms of blood imbalances may include weakness, anemia, and poor appetite. Treatment for blood imbalances may involve the use of nourishing and tonifying herbs and acupuncture points to support and nourish the body’s tissues and organs.
- Body fluids: Body fluids are the vital substances that are believed to moisten and nourish the body’s tissues and organs. Symptoms of body fluid imbalances may include dry skin, dry mouth, and constipation.
Triple Burner (San Jiao)
In traditional Chinese medicine (TCM), the concept of pattern/syndrome differentiation using the triple burner (San Jiao) refers to the use of the triple burner system to diagnose and treat imbalances or conditions. In TCM, the triple burner is a system of three interconnected organs that are believed to be responsible for the regulation of the body’s temperature, fluids, and circulation.
TCM practitioners use the concept of the triple burner to identify patterns of imbalance or disharmony in the body and to develop a treatment plan to restore balance and promote health. To do this, practitioners may assess the patient’s symptoms, observe the body, and take a detailed medical history to gather information about the patient’s overall health and any imbalances or conditions present.
There are three main organs in the triple burner system:
- Upper burner: The upper burner is responsible for the regulation of the body’s fluids and is associated with the lung and large intestine. Symptoms of upper burner imbalances may include respiratory issues, constipation, and dryness.
- Middle burner: The middle burner is responsible for the regulation of the body’s temperature and is associated with the stomach and spleen. Symptoms of middle burner imbalances may include poor appetite, bloating, and indigestion.
- Lower burner: The lower burner is responsible for the regulation of the body’s circulation and is associated with the small intestine and bladder. Symptoms of lower burner imbalances may include irregular menstruation, blood disorders, and urinary issues.
TCM practitioners use the triple burner concept in combination with other diagnostic tools, such as observation of the body and assessment of symptoms, to identify patterns of imbalance or disharmony in the body and to develop a treatment plan to restore balance and promote health.

The 12 Main Meridians in TCM and Their Naming Conventions
Each of the 12 main meridians in Traditional Chinese Medicine (TCM) is named based on three key factors: the associated organ, the location (hand or foot), and its yin or yang classification according to the Six Divisions theory. Below is a detailed explanation of each meridian and its naming conventions.
Lung Meridian (Hand Taiyin)
In Traditional Chinese Medicine (TCM), the Lung Meridian (Hand Taiyin) is named based on its association with the Lung organ, its location in the upper body, and its classification as a Yin meridian.
Here’s a breakdown of the name:
1. Lung:
The meridian is associated with the Lung organ, which plays a crucial role in governing respiration, Qi (vital energy), and the distribution of fluids in the body. The Lung is responsible for taking in pure Qi from the air (through breathing) and expelling impure Qi. It also regulates the opening and closing of the skin pores, thereby controlling sweating and defending the body against external pathogens. Imbalances in the Lung meridian can manifest as respiratory issues (e.g., cough, asthma), skin problems, and weakened immunity.
2. Hand:
The Lung meridian is classified as a “Hand” meridian because it begins in the hand and runs along the arm. Specifically, it starts in the chest, descends internally to connect with the Lung organ, and then emerges to travel down the arm, ending at the thumb. This distinguishes it from meridians associated with the lower body or legs (such as the Foot Jueyin Liver Meridian).
The “Hand” classification helps practitioners locate the meridian’s pathway and its relation to symptoms that may manifest in the upper body, such as arm pain or difficulty breathing.
3. Taiyin:
The Lung Meridian is classified as Taiyin, which means Greater Yin. In TCM’s Six Divisions theory, Taiyin represents the most external layer of yin meridians, focusing on nourishment and protection. The Taiyin designation refers to the Lung’s role in receiving and dispersing Qi, which affects the surface layers of the body, such as the skin and mucous membranes.
The Lung Meridian is the most superficial of the Yin meridians, meaning it is often the first line of defense against external pathogens (e.g., wind or cold), making it essential in treating external illnesses like colds or flu.
Summary:
- Lung: The meridian corresponds to the Lung organ, which governs breathing, Qi distribution, and fluid regulation.
- Hand: The meridian runs through the arm and ends in the hand, focusing on upper-body functions.
- Taiyin: The Lung Meridian is categorized as “Greater Yin,” reflecting its role in protecting the body and controlling surface-level defenses like the skin and respiration.
This name helps practitioners understand its function and location, enabling them to diagnose and treat imbalances affecting the respiratory system, skin, and immune functions. By stimulating acupuncture points along the Lung Meridian, practitioners can restore balance, strengthen the Lungs, and enhance the body’s ability to fight off external pathogens.
Large Intestine Meridian (Hand Yangming)
In Traditional Chinese Medicine (TCM), the Large Intestine Meridian (Hand Yangming) is named based on its association with the Large Intestine organ, its location in the upper body, and its classification as a Yang meridian.
Here’s a breakdown of the name:
1. Large Intestine:
The meridian is associated with the Large Intestine organ, which is responsible for absorbing water from digested food and eliminating waste from the body. The Large Intestine works closely with the Lung in regulating the body’s fluid balance and promoting healthy bowel function. Imbalances in the Large Intestine meridian can manifest as constipation, diarrhea, abdominal pain, or other digestive disturbances, as well as skin problems such as rashes or acne, which are seen as external manifestations of internal heat or dampness.
2. Hand:
The Large Intestine meridian is classified as a “Hand” meridian because it begins in the hand and runs along the arm. Specifically, it starts at the tip of the index finger, travels up the arm, and continues toward the face, ending near the side of the nose. This connection between the hand and face is essential in treating conditions like toothache, facial pain, or nasal congestion, which can be related to imbalances in the Large Intestine meridian.
The “Hand” designation differentiates it from meridians that run through the lower body (such as the Foot Yangming Stomach Meridian), emphasizing its role in treating conditions affecting the upper body.
3. Yangming:
The Large Intestine Meridian is classified as Yangming, which refers to Bright Yang, the most yang (active) phase within the Six Divisions theory of TCM. Yangming meridians, which include both the Large Intestine and the Stomach meridians, are highly active and full of energy. Yangming is known for generating and dispersing heat and Qi and is related to both the digestive process and the exterior of the body.
The Yangming meridians are often associated with heat syndromes, such as fever, inflammation, or red, swollen skin. In the case of the Large Intestine meridian, Yangming heat can manifest as heat in the intestines, leading to conditions like constipation, or as heat rising to the face, causing swelling, toothache, or acne.
Summary:

Stomach Meridian (Foot Yangming)
In Traditional Chinese Medicine (TCM), the Stomach Meridian (Foot Yangming) is named based on its association with the Stomach organ, its location in the lower body, and its classification as a Yang meridian.
Here’s a breakdown of the name:
1. Stomach:
The meridian is associated with the Stomach organ, which is responsible for receiving, digesting, and transforming food into nutrients that are then used to produce Qi (vital energy) and Blood. The Stomach works in close harmony with the Spleen to manage the body’s digestive functions. Imbalances in the Stomach meridian can manifest as poor digestion, bloating, nausea, vomiting, or acid reflux. Stomach heat can also cause issues such as thirst, bad breath, and gum inflammation. As the Stomach plays a key role in digestion, it is central to overall health in TCM, making it a frequently targeted meridian in treatment.
2. Foot:
The Stomach meridian is classified as a “Foot” meridian because it begins in the face and travels down the body, ending in the foot. It starts at the lateral side of the nose, travels down the cheeks, passes through the throat, descends through the chest and abdomen, and continues down the leg, ending at the second toe. This extensive pathway means that the Stomach meridian is involved in treating a wide variety of conditions, from facial pain and toothache to abdominal disorders and leg pain.
The “Foot” classification helps to differentiate it from upper body meridians (like the Hand Yangming Large Intestine Meridian) and indicates its relevance in treating conditions related to the lower extremities and digestive system.
3. Yangming:
The Stomach Meridian is classified as Yangming, which refers to Bright Yang, a phase within the Six Divisions theory of TCM that is highly active and yang in nature. The Yangming meridians, which include both the Stomach and the Large Intestine meridians, are known for being full of Qi and Blood. The Yangming classification reflects the meridian’s energetic and heat-generating nature, making it susceptible to heat conditions such as fever, inflammation, and hyperactive digestion.
Yangming heat in the Stomach may manifest as acid reflux, burning sensations in the epigastrium, or excessive hunger. Alternatively, Stomach Qi deficiency may result in poor appetite, fatigue, and indigestion. As a Yangming meridian, the Stomach plays a vital role in balancing the body’s energetic needs and digestive health.
Summary:
- Stomach: The meridian corresponds to the Stomach organ, which governs the transformation of food into Qi and Blood, playing a critical role in digestion and nutrient absorption.

Herbal treatments and lifestyle adjustments, including stress management techniques and dietary changes, also support the Gallbladder’s function in digestive health, decision-making, and emotional regulation.
Liver Meridian (Foot Jueyin)
In Traditional Chinese Medicine (TCM), the meridian system is named based on several factors, including the organ it is associated with, the location on the body, and its yin or yang classification.
Let’s break down why it is called the Liver Meridian (Foot Jueyin):
1. Liver:
The meridian is associated with the Liver organ in the Zang Fu system. The Liver is responsible for storing blood, regulating the smooth flow of Qi throughout the body, and governing emotional health. Imbalances in the Liver can manifest as emotional disturbances (like anger or frustration), Qi stagnation, or physical symptoms such as hypochondriac pain and digestive issues.
2. Foot:
The meridians are divided into pathways that either start or end in the hands or feet, corresponding to their broader pathways through the body. The Liver meridian is named the “Foot” Liver Meridian because it originates in the foot and runs upward along the inner leg, passing through the groin, abdomen, and chest before reaching the Liver organ.
This distinction helps differentiate the Liver meridian from other meridians that may be associated with the upper body or hands (such as the Lung meridian, which is categorized as “Hand Taiyin”).
3. Jueyin:
In TCM, each meridian is also classified according to its yin or yang nature and its depth in the body. The Liver Meridian is called Jueyin because it is a Yin meridian (associated with storing and nourishing functions), and “Jueyin” refers to a deep yin or “reverting yin” phase.
The meridian classifications are based on the Six Divisions theory, which groups meridians into three levels of yin and yang:
- Taiyin (Greater Yin)
- Shaoyin (Lesser Yin)
- Jueyin (Reverting Yin)
The Liver Meridian is classified as Foot Jueyin because it is a yin meridian that runs through the lower part of the body (the foot) and belongs to the deepest, most internal yin layer.
Summary:
