I am Master Visuddhi Lee, an acupuncturist from Malaysia, and for nearly two decades I have dedicated myself to exploring the profound wisdom of Traditional Chinese Medicine (TCM). Though increasingly recognized worldwide, TCM’s principles—such as the heart as the seat of the mind, the liver’s link to anger, and the kidneys’ role in reproduction—often remain difficult to grasp. To bridge this gap, I created a 55-video series, The Principles and Practice of TCM, which distills centuries of knowledge into clear, practical lessons for both healthcare professionals and the general public. Covering core concepts like Yin and Yang, the Five Elements, Zang Fu syndromes, diagnostic methods, Chinese herbs, and more, this series aims to make TCM accessible, relatable, and transformative. My mission is to guide you in discovering how harmony with nature fosters health and balance, and to share how TCM’s timeless principles can enrich your daily life and well-being.
Traditional Chinese Medicine (TCM) has a history spanning thousands of years, originating in ancient China during the Shang and Zhou Dynasties, where early practices were shaped by observations of nature and the body. Influenced by Daoist concepts of Yin, Yang, and qi, as well as Confucian ideals of harmony, TCM developed a holistic medical framework that was formalized in classical texts such as the Yellow Emperor’s Inner Canon and the Classic of Herbal Medicine. Over centuries, it evolved diagnostic techniques like pulse and tongue examination, alongside therapies such as herbal medicine, acupuncture, moxibustion, and mind-body practices like Tai Chi and Qi Gong. With the modernization and global spread of TCM in the 20th century, it continues to be valued worldwide for its holistic approach to health and healing. This series by Master Lee’s School of Acupuncture will further explore TCM’s core theories and practices, from Yin-Yang and Five Elements to herbology and Qigong.
In the context of health and wellness, when people get sick, their Yin and Yang balance can be out of equilibrium, leading to symptoms like heat, overactivity, or feeling colder and more tired. The practitioner assesses the relative balance between Yin and Yang in each person. Knowing this, the therapist can then prescribe treatment to re-establish balance, thus restoring health.
The properties of Yin and Yang form an intricate balance that is key to understanding TCM and its approach to health and wellness. Understanding these properties can provide a unique perspective on health and healing.
Understanding these four characteristics helps TCM practitioners diagnose and treat imbalances in the body. The aim is to restore harmony and health by rebalancing the Yin and Yang energies. This holistic approach, focusing on the body's overall balance rather than isolating symptoms, is what sets TCM apart from other healthcare practices.
Understanding of Yin and Yang dynamics can guide practitioners in tailoring treatment plans to address specific imbalances and promote overall health and well-being.
Qi is the vital energy or life force that flows through the body. In TCM, it is considered as matter and energy, material and immaterial, process, function, movement, circulation. It is the most fundamental substance comprising human beings and is that which makes up all phenomena in the universe.
According to TCM theory, Qi flows through the body along specific pathways called meridians, forming a complex network that connects various organs, tissues, and functions.
The smooth and balanced flow of Qi is essential for maintaining health, while disruptions or blockages in its movement can lead to disease or disharmony. The movements of Qi in TCM are described in several ways, each representing different aspects of its dynamic nature. These include:
Circulating Qi (Xing Qi)
Ascending Qi (Sheng Qi)
Descending Qi (Jiang Qi)
Outward Qi (Chong Qi)
Inward Qi (Ju Qi)
Understanding the movements of Qi in TCM is crucial for diagnosing and treating imbalances or disorders.
Here are some common Qi-related disorders in TCM:
Qi Deficiency
Qi Stagnation
Qi Rebellion
Qi Sinking
Qi Heat
Qi Cold
Treatment of Qi-related disorders in TCM often involves acupuncture, herbal medicine, dietary therapy, lifestyle modifications, and mind-body practices such as qigong or tai chi.
In Chinese medicine, Blood is considered the nurturing force, belonging to the Yin aspect as it is dense and fluid. It carries nutrients and nourishes the body. For Blood to do its job effectively, it needs Qi, another vital substance, to push it around the body.
In Chinese medicine, when looking at a person's health, practitioners often consider the balance and interaction between Qi and Blood. A harmonious interplay between these two vital forces contributes to overall well-being, while imbalances can lead to a variety of health issues.
Body Fluids, or Jin Ye, are one of the vital substances in our body. Among all the vital substances, Body Fluids are the most "substantial," having a Yin nature. This contrasts with the Shen, which is the most "insubstantial."
Body Fluids can be divided into two types: Jin and Ye.
Understanding the relationship between Body Fluids and Blood is crucial to holistic healthcare treatment. In Traditional Chinese Medicine, it is essential to view the body as a whole, interconnected system where each part supports and influences the others. The balance and harmony between these parts are what lead to overall health and wellbeing.
By appreciating the role of each organ in the formation and regulation of body fluids, we can better understand the interconnectedness of our bodily systems and how imbalances can impact our health. This knowledge is key in TCM's holistic approach to health, which seeks to address the root causes of health issues, rather than simply treating symptoms.
In the realm of Traditional Chinese Medicine, there exists a unique vital substance known as 'Essence' or 'Jing'. This concept is integral to understanding the principles of Chinese Medicine, acting as the foundation for many of its theories and practices. Essence is responsible for things as diverse as our growth development, our fertility, and the physical decay of our bodies. Essence is believed to be the basic constitutional strength, vitality, and resistance of the body.
Three 'Types' of Essence
In Chinese Medicine, Essence is typically divided into three 'types': Pre-natal Essence, Post-natal Essence, and Kidney Essence.
The Essence (Jing) in Traditional Chinese Medicine plays a vital role in promoting growth, reproduction, and aging. It forms the basis for Kidney Qi, produces Marrow, and underpins our constitutional strength. It is also one of the 'Three Treasures', alongside Qi and Mind. Understanding and maintaining the balance of our Essence is crucial for overall health and well-being. Remember, in Chinese medicine, the path to health is all about balance and harmony.
Shen encompasses various aspects of consciousness, emotions, spirituality, and physical health in TCM. Cultivating a balanced Shen is considered essential for achieving holistic health and harmony within oneself and the surrounding environment. By addressing imbalances in Shen through appropriate TCM modalities, individuals can promote overall well-being and cultivate a deep sense of vitality and inner peace.
The Zang and Fu organs operate in harmony, akin to a well-coordinated team. Each organ has its designated role, and optimal health is achieved when all organs perform their functions efficiently and in balance. Maintaining this balance between the Zang and Fu organs is paramount for good health in TCM philosophy. Imbalances, whether due to excessive activity, deficiency, or stagnation in any organ, can lead to disharmony and illness.
The Relationship Between Zang-Fu Organs
The unique relationship between these organ groups is established through the connections of their channels and collaterals. This interior-exterior association is evident in the physiological cooperation and pathological interactions observed between the organs.
TCM emphasizes the importance of maintaining harmony between the interior and exterior organs for optimal health. When the interior organs are strong and balanced, they support the proper functioning of the exterior organs, leading to overall well-being.
In the theory of Zang Fu Organ in TCM, the heart is revered as a Yin Zang Organ. It is often referred to as the "Monarch" or Ruler of all organs, indicating its importance in maintaining overall health. The key functions of the heart in TCM are to control the flow of blood, the blood vessels, and to house the spirit or mind.
In Chinese Medicine, the kidneys are associated with various functions related to the balance of Yin and Yang, the storage of essence, and the regulation of water metabolism.
In TCM, the Liver is associated with the Wood element and is believed to govern the smooth flow of Qi, or vital energy, throughout the body. This ensures the flow of Qi reaches all organs and directions. Any imbalance in the Liver's function can significantly influence our emotional well-being, as the obstruction of Liver Qi can lead to emotional fluctuations, suppressed anger, and irritability.
In Chinese medicine, the Lung system is associated with the Metal element and the color White. It's influenced by emotions like Grief and Sadness and has a downward movement. The sense organ linked with Lungs is the Nose, and it pairs with the Large Intestine.
In TCM, the spleen is considered one of the major Zang organs responsible for various physiological functions, particularly digestion. However, it's important to note that the concept of the spleen in TCM differs from its anatomical understanding in Western medicine. The TCM concept of the spleen includes the functions of both the Western spleen and pancreas.
In Traditional Chinese Medicine, the Bladder is one of the six Fu organs. Its primary role involves receiving, storing, and expelling urine. It plays a significant part in the body's water metabolism system, where body fluids circulate throughout the body to moisturize tissues and organs.
The Gallbladder is associated with the Wood element and the color green. It influences our emotions, particularly our courage or lack of it, as well as feelings of bitterness and resentment. Its movement is outward and upward, and its sense organ is the eyes. It is paired with the Liver organ and corresponds to the Western association of the gallbladder.
In addition to bile, it is also associated with tendons/sinews, ears, and the sides/flanks of the body. Common conditions related to the Gallbladder system include gallbladder disease, liver disease, digestive disorders, muscle aches and pains, tight tendons, rigidity, eye disorders, headaches, dizziness, ear disorders, chest or rib pain, difficulty making decisions, impulsiveness, and conditions that occur on only one side of the body.
Understanding the role and functions of the Gallbladder in TCM offers a unique perspective on how our body systems interact and influence our overall health and wellbeing. This knowledge can be a valuable tool for healthcare professionals looking to incorporate a holistic approach into their practice.
The Liver, a Zang Organ, is the 'General' for the body because it is responsible for overall planning of the body’s functions by ensuring the smooth flow and proper direction of Qi. It also stores the Blood and regulates the amount of Blood circulated by the Heart.
The Sanjiao’s main functions are to energize the body, regulate metabolism and digestion, manage fluids, and protect the body’s organs and muscles. Because it is not a true organ, it does not have any associated disease patterns. Still, the Sanjiao greatly influences our health and impacts how all our other organ systems function.
In Traditional Chinese Medicine (TCM), the Small Intestine is considered one of the six Fu organs. The Fu organs, being Yang in nature, are responsible for the processing and transformation of substances rather than storage, in contrast to the Yin Zang organs.
In TCM, the Stomach is considered a crucial player in our overall health. Unlike the Western view which strictly confines the stomach's role to digestion, TCM interprets it as an integral part of our bodily functions, influencing everything from our appetite to the coating on our tongues.
Positioned beneath the diaphragm, the Stomach's primary tasks are 'receiving' food and drink through the mouth, pharynx, and esophagus and retaining them for digestion. This 'receiving' function has a significant influence on our appetite. A strong and healthy appetite is indicative of a robust Stomach 'receiving' ability. On the other hand, a complete loss of appetite, hiccups, nausea, and vomiting could signify a weakened Stomach function.
The Five Element or Phases theory is a cornerstone of Traditional Chinese Medicine, providing a framework for understanding our bodies, emotions, and health. By understanding these elements, we can lead healthier, more balanced lives.
The Five Element Cycle, also known as the Generating Cycle or the Sheng Cycle, is a fundamental concept within Traditional Chinese Medicine (TCM) that describes the dynamic relationships between the five elements: Wood, Fire, Earth, Metal, and Water. This cycle illustrates how these elements interact with and support each other, contributing to the maintenance of balance and harmony within the body and the natural world.
The Five-Phases theory elucidates the interconnectedness of different organs and how imbalances in one can influence another. For instance, if a disease originates in the Kidney, which is associated with the Water element, it may have a tendency to spread to the Heart, represented by Fire, and vice versa. Similarly, the suppression of the Spleen (Earth) by the Liver (Wood) can indicate that a disease affecting the Heart (Fire) may also be present in the Liver (Wood).
TCM emphasizes maintaining harmony with these external elements to preserve health and prevent disease. It highlights the importance of balance within the body and its environment. By understanding these external causes of diseases, healthcare professionals can incorporate TCM principles into their practice, offering holistic care to their patients.
In Traditional Chinese Medicine (TCM), the concept of "cold" (寒, hán) is considered one of the external causes of diseases, alongside wind, heat, summer-heat, dampness, and dryness. Cold is a Yin pathogenic factor. Cold can refer to both an exterior condition and an internal imbalance within the body.
Treatment in TCM for conditions related to cold typically involves warming and dispersing cold, nourishing Yang Qi, and promoting the smooth flow of Qi and Blood. This may involve the use of acupuncture, moxibustion, herbal medicine, dietary adjustments (such as consuming warming foods and avoiding cold or raw foods), and lifestyle modifications (such as staying warm and avoiding exposure to cold and damp environments).
Dampness can result from exposure to damp environments or consuming damp-producing foods. Damp conditions may lead to symptoms such as heaviness, swelling, and a feeling of lethargy.
Damp conditions require time and patience to treat. Dampness-removing diets are often necessary and include the elimination of 'sodden' foods such as high fat, oils, sugar, dairy and flour products. A simple diet is recommended based on low or nonfat foods including whole grains, beans and vegetables.
Dryness arises when there is an excess of Yang energy or a deficiency of Yin energy in the body. This imbalance can manifest physically, emotionally, and mentally.
Fire, a yang pathogenic factor, is characterized by upward flaming. When Fire attacks the body, it may give rise to high fever, thirst, sweating, and a surging, rapid pulse. The mind may also be disturbed. Understanding the characteristics of Fire (Heat) can help healthcare professionals provide more comprehensive care, incorporating the ancient wisdom of TCM into modern practices.
In TCM, Wind is seen as a major external cause of diseases. It is Yang in nature and tends to injure Blood and Yin. Wind invades the body from outside when the vital energy (Qi) loses the ability to protect the body. Wind is regarded both as an external pathogenic factor and an internal manifestation of imbalance. Hence, Wind in TCM is a complex concept that combines climate, bodily reactions, and symptoms of diseases.
In TCM, Summer-Heat is considered one of the six external pathogenic factors, alongside wind, cold, dampness, dryness, and fire. It is particularly relevant during the summer season when temperatures are high and humidity levels rise. Summer-heat pertains to Yang and is hot in nature. The disease caused by summer-heat is usually marked by a series of yang symptoms such as high fever, dysphoria, reddish complexion, thirst with preference for cold drink and full and large pulse. In the West, it is often referred to as heat stroke.
While the terminology and concepts may differ between traditional Chinese medicine and modern medicine, there are parallels between the Six Evils and the factors that contribute to the spread and manifestation of viral and bacterial infections. Understanding these parallels can provide insights into both traditional and contemporary approaches to preventing and treating infectious diseases.
In TCM, the Seven Internal Causes or Seven Emotions, contrary to Western Medicine beliefs, are not isolated in the brain but are intricately linked to our physical health. The emotions form physical-emotional spheres of influence together with the organs. Under normal conditions, these emotions are harmless. However, when they are sudden, strong or long-lasting, they can surpass a person's physiological endurance, disrupt the function of the Zang and Fu organs and become the seven pathogenic factors.
The Role of Diet, Work, and Rest
In the theory of Chinese medicine, maintaining a balance between diet, work, and rest is crucial for good health and disease prevention. Mismanagement in these areas can affect the physiological functions of the Zang-fu organs, thereby reducing the body's resilience to illness. In the context of TCM, these imbalances become pathogenic factors.
TCM diagnostics aim to uncover the root cause of illness by considering the interconnectedness of body, mind, and environment. By understanding the unique constitution and imbalances of each individual, TCM practitioners can tailor treatments to restore harmony and promote overall health and well-being. Embrace this ancient wisdom of health and wellness and embark on a journey of holistic healing with Traditional Chinese Medicine.
This module focuses on the first examination, "Inquiry or Asking." The principle of inquiry aims to collect subjective information directly from the patient, helping the practitioner understand the nature, duration, and progression of the illness.
The process of inspection in TCM involves a detailed examination of the patient's facial complexion and expression, tongue, body build and posture, movements and gait, eyes, ears, nose, mouth, hair, skin, and nails. This technique underscores the holistic approach of TCM in diagnosing and treating ailments, emphasizing the interconnectedness of our external features with our internal health.
Overall, tongue diagnosis is a valuable diagnostic method in TCM that provides insights into the patient's internal health and patterns of disharmony. By carefully observing the appearance of the tongue, TCM practitioners can tailor treatment plans to address the root causes of illness and promote holistic healing.
"Listening and Smelling", also known as "auscultation and olfaction".
This diagnostic method involves paying attention to the sounds and smells associated with the patient's body. These may provide valuable information about internal imbalances and patterns of disharmony.
The process of Palpation in TCM involves various techniques such as Pulse Diagnosis, Abdominal Palpation, Meridian Palpation, Back Palpation, Joint Palpation, Skin Palpation, Tender Points and Ashi Points, Temperature Palpation, and Pain Palpation. By integrating these techniques with other examinations, practitioners can achieve a comprehensive understanding of a patient's health status and devise a targeted treatment plan.
In TCM, different pulse positions correspond to specific organ systems and meridians in the body. For example, the pulse position on the left wrist relates to the Heart, Liver, and Kidney meridians, while the right wrist corresponds to the Lung, Spleen, and Kidney meridians. By palpating these positions and assessing changes in pulse characteristics, practitioners can identify imbalances in the corresponding organs and meridians, guiding diagnosis and treatment.
The Eight-Principles Syndrome Differentiation can be divided into four pairs: Cold or Heat, Interior or Exterior, Deficiency or Excess, and Yin or Yang. These distinctions within each pair allow practitioners to paint a detailed picture of the nature, location, and dynamics of the health issue. By understanding these different syndromes, treatments to restore balance and harmony within the body can be tailored.
The Six Stages Theory, also known as the "Six Divisions" or "Six Channels" theory, is a fundamental concept in Traditional Chinese Medicine (TCM). It describes the progression of a pathogenic factor through the body and the corresponding symptoms that arise at each stage.
Traditional Chinese Medicine (TCM) is a holistic healthcare system that focuses on restoring balance and harmony within the body by addressing the root causes of illness rather than just symptoms. Its treatment principles revolve around identifying patterns of disharmony through detailed diagnosis, restoring the smooth flow of Qi via techniques like acupuncture and Qi Gong, and regulating the Yin-Yang balance through herbs, diet, and lifestyle changes. Practitioners also aim to tonify deficiencies, reduce excess, clear pathogenic heat and dampness, promote circulation to resolve stagnation, and harmonize the functions of the Zang-Fu organs. By tailoring treatments to each individual’s constitution and condition, TCM supports the body’s innate healing ability, offering a comprehensive path to health and well-being.
Traditional Chinese Medicine (TCM) employs eight distinctive treatment methods that work together to restore balance and health: Sweating Therapy (to release external pathogens through induced perspiration), Vomiting Therapy (to expel harmful substances from the stomach), Bowel-Cleansing Therapy (to clear internal accumulations and promote bowel movements), Balancing Therapy (to harmonize organ functions and relieve disharmony), Warming Therapy (to dispel cold and support Yang energy), Clearing Therapy (to eliminate excess heat and inflammation), Nourishing Therapy (to tonify Qi, Blood, Yin, and Yang in deficiency states), and Resolving Therapy (to dissolve accumulations and aid digestion). Through acupuncture, herbal medicine, moxibustion, and dietary applications, these methods provide a comprehensive, adaptable system of healthcare that addresses both the root and symptoms of disease.
Acupuncture, channels, and collaterals form the foundation of Traditional Chinese Medicine (TCM), emphasizing the body as an interconnected network of energy pathways. Acupuncture involves stimulating specific points to regulate the flow of Qi and blood, while moxibustion uses burning mugwort to warm and activate these points. The meridian system, consisting of 14 primary channels and numerous smaller collaterals, transports Qi, blood, and fluids, coordinates organ functions, and defends against external pathogens. Each meridian corresponds to vital physiological and emotional roles, while collaterals—such as Luo, Divergent, Sinew, and Cutaneous—extend their influence to deeper organs, muscles, joints, and the skin. Together, this system explains how stimulation at one point can affect distant parts of the body, providing a holistic framework for diagnosis and treatment in TCM.
Chinese herbal medicine, a core component of Traditional Chinese Medicine (TCM), uses a wide range of substances—including herbs, minerals, and animal products—to restore balance and treat illness. Herbs are classified by the Four Natures (Cold, Cool, Warm, Hot) that reflect their thermal qualities, and the Five Flavors (Sweet, Sour, Bitter, Spicy, Salty) that determine their therapeutic actions. Practitioners combine these properties into carefully balanced formulas, structured with chief, deputy, assistant, and envoy herbs to address primary imbalances, support secondary issues, enhance effectiveness, and harmonize actions. These formulas may be prescribed individually or provided as ready-made patent remedies. While rooted in ancient tradition, Chinese herbal medicine continues to evolve, with modern research exploring its efficacy and safety, creating a bridge between traditional wisdom and contemporary healthcare.
Chinese dietary therapy, a core practice of Traditional Chinese Medicine (TCM), treats food as both nourishment and medicine, aiming to balance Yin and Yang, regulate Qi, and support overall harmony in the body. Foods are classified by their energetic nature (cooling or warming), five flavors (spicy, salty, sweet, sour, bitter), and their effects on specific organ systems. Diet is also adapted to seasonal changes—light and cooling foods in summer, warming and hearty foods in winter—and personalized based on an individual’s constitution, health condition, and lifestyle. Cooking methods, such as slow-cooking for weak digestion or stir-frying for cold conditions, further influence a food’s therapeutic effect. Alongside food choice, mindful eating—eating slowly, chewing well, and listening to the body—enhances digestion and absorption. Altogether, TCM dietary therapy provides a holistic, adaptable framework for preventing disease and promoting vitality through everyday meals.
In Traditional Chinese Medicine (TCM), exercise is a vital practice for maintaining health by ensuring the smooth flow of Qi, strengthening the body, balancing Yin and Yang, supporting organ function, and clearing blockages that cause illness or discomfort. Beyond physical benefits, TCM exercises also enhance mental and emotional well-being by reducing stress and promoting mindfulness. Popular practices include Tai Chi, Qigong, Ba Duan Jin (Eight Brocades), Yijinjing (Muscle/Tendon Changing Classic), and Dao Yin, each combining movement, breathing, and intention to harmonize the body’s energy. Regular practice of these exercises, alongside acupuncture, herbal medicine, and dietary therapy, offers a holistic path to balance, vitality, and longevity.
Tuina, or Tui Na, is a core modality of Traditional Chinese Medicine (TCM) that uses therapeutic massage and acupressure techniques to regulate the flow of Qi and blood, restore balance, and support overall health. By manipulating the body’s soft tissues, tendons, ligaments, and joints, Tuina helps promote circulation, harmonize Yin and Yang, relieve pain, improve organ function, enhance emotional well-being, and strengthen the body’s resistance to disease. Its wide range of techniques—including pressing, kneading, rubbing, rolling, vibrating, pinching, twisting, pulling, joint mobilization, and stretching—are customized to the individual’s condition and needs, making Tuina both a healing therapy and a preventative practice for maintaining vitality and wellness.
