Zangfu pattern identification
A core TCM diagnostic method that identifies disease patterns based on the physiological functions and pathological characteristics of the Zang (solid) and Fu (hollow) organs, their interrelationships, and how imbalances manifest in signs and symptoms. It is the foundation for analyzing interior and chronic conditions.

Overview
Zangfu pattern identification (臟腑辯證, Zàng Fǔ Biàn Zhèng) is one of the most widely used diagnostic frameworks in Traditional Chinese Medicine. Think of it as a systematic method for understanding which internal organs are out of balance and how this imbalance manifests in the body.
In TCM, the "organs" are not simply the physical structures you might think of from Western anatomy. Instead, each organ represents a network of related functions, including physical, emotional, and energetic aspects. For example, the TCM "Liver" is associated with emotional regulation, smooth flow of energy, and eye health—far beyond its digestive role in Western medicine. Zangfu pattern identification analyzes the signs and symptoms of disease according to the physiological functions and pathological characteristics of these organ systems, allowing practitioners to infer the etiology, pathology, location, and nature of a disease.
This diagnostic method is especially valuable for chronic and internal conditions—situations where disease has moved beyond the surface of the body and is affecting the core organ systems. By understanding which specific organ (or combination of organs) is involved and whether the problem involves excess or deficiency, heat or cold, practitioners can create targeted and effective treatment plans.
Historical Context
Zangfu pattern identification has its roots in the Huangdi Neijing (Yellow Emperor's Classic of Internal Medicine), composed during the Warring States period through the Han Dynasty (approximately 475 BCE – 220 CE). The Neijing established the foundational Zangxiang (organ manifestation) theory that underlies this diagnostic approach. The text describes organs using the metaphor of government officials, with the Heart as the "ruler" from which spirit emanates.
The method was further developed during the Tang, Song, Jin, and Yuan dynasties (roughly 7th-14th centuries CE), when physicians refined the clinical application of organ theory to internal medicine. It became the primary diagnostic framework for internal and chronic diseases, complementing other methods like Six Stages (for acute febrile diseases) and Wei-Qi-Ying-Xue (for warm diseases). Today, Zangfu pattern identification remains the most commonly used diagnostic framework in TCM clinical practice worldwide.
Comparison
Zang Organs (Solid/Yin)
脏Five solid organs (Heart, Liver, Spleen, Lung, Kidney) that store vital substances. Their patterns typically involve deficiency conditions. They are the primary focus of pattern identification.
Fu Organs (Hollow/Yang)
腑Six hollow organs (Gallbladder, Stomach, Small Intestine, Large Intestine, Bladder, San Jiao) that receive, transform, and transport. Their patterns often involve excess and Damp-Heat conditions.
Single Organ Patterns
单一脏腑证Patterns affecting one organ (e.g., Heart Qi Deficiency, Liver Fire). These are foundational patterns students learn first.
Combined Organ Patterns
脏腑兼病Patterns involving two or more organs simultaneously (e.g., Heart-Kidney Not Communicating, Liver-Spleen Disharmony). These require understanding organ relationships.
Deficiency Patterns
虚证Patterns where organ function is weakened—Qi, Blood, Yin, or Yang deficiency. Treatment principle is to tonify and support.
Excess Patterns
实证Patterns involving accumulation or stagnation—Fire, Phlegm, Blood stasis, Qi stagnation, Dampness. Treatment principle is to clear, drain, or move.
Five Zang Organs
五脏 (Wǔ Zàng)The five solid (Yin) organs—Heart, Liver, Spleen, Lung, and Kidney—are the core of Zangfu theory. These organs store vital substances (Qi, Blood, Essence, Fluids) and are central to pattern identification. Each has specific physiological functions and associated symptoms when imbalanced.
Six Fu Organs
六腑 (Liù Fǔ)The six hollow (Yang) organs—Gallbladder, Stomach, Small Intestine, Large Intestine, Bladder, and San Jiao (Triple Burner)—transform and transport substances rather than storing them. They are paired with Zang organs in Yin-Yang relationships.
Organ Interrelationships
脏腑关系Organs don't exist in isolation—they generate, control, and influence each other following Five Element relationships and Yin-Yang pairings. Understanding these connections helps practitioners identify how disease spreads between organs (e.g., Liver affecting Spleen, Kidney affecting Lung).
Combined Patterns
脏腑兼病Clinical reality often involves multiple organs. Practitioners must identify when pathology affects more than one organ system and understand the causal relationships between them—determining which is primary and which is secondary.
Integration with Eight Principles
结合八纲Zangfu diagnosis works hand-in-hand with Ba Gang (Eight Principles) to specify not just which organ is affected, but also the nature of the imbalance—whether it's Yin/Yang, Interior/Exterior, Cold/Hot, or Deficient/Excess.
Practical Application
In clinical practice, Zangfu pattern identification begins with gathering information through the Four Examinations (looking, listening/smelling, asking, and pulse-taking). The practitioner then analyzes symptoms to determine: (1) which organ or organs are affected, (2) whether the pattern is deficient or excess, (3) whether it involves cold or heat, and (4) how the condition relates to Qi, Blood, Yin, or Yang.
For example, a patient presenting with fatigue, poor appetite, loose stools, and a pale tongue might be diagnosed with Spleen Qi Deficiency. Another patient with emotional irritability, headaches at the temples, and a wiry pulse might have Liver Qi Stagnation. Once the pattern is identified, treatment principles follow logically—tonify what is deficient, clear what is excess, warm what is cold, cool what is hot.
Zangfu diagnosis is particularly valuable for chronic and complex conditions where multiple systems may be involved. Practitioners often identify both a primary pattern (the root cause) and secondary patterns, then prioritize treatment accordingly. This method guides both acupuncture point selection and herbal formula composition.
Clinical Relevance
Zangfu pattern identification is the foundation for clinical analysis and differentiation of every disease in TCM, particularly for interior and chronic conditions. It allows practitioners to move beyond symptom management to address the underlying organ dysfunction causing disease. All physiological functions and pathological changes are associated with the Zangfu organs, and most often, the occurrence and development of disease results from organ dysfunction.
In practice, even other diagnostic frameworks (like Six Stages or Four Levels for acute febrile diseases) eventually resolve into Zangfu patterns as conditions progress or become chronic. The method integrates seamlessly with herbal medicine, where formulas are designed to address specific organ imbalances, and with acupuncture, where point selection follows organ-meridian relationships. This makes Zangfu diagnosis applicable across all TCM clinical specialties including internal medicine, gynecology, pediatrics, and dermatology.
Common Misconceptions
"TCM organs are the same as Western anatomical organs." This is perhaps the most common misunderstanding. While names overlap, TCM organs represent functional networks encompassing physical, energetic, and emotional aspects. The TCM "Spleen," for instance, governs digestion and transformation—functions Western medicine attributes mainly to the stomach and pancreas. The TCM "Kidney" relates to growth, reproduction, and constitutional strength, extending far beyond urinary function.
"One organ pattern at a time." Beginners often expect to find a single, clean pattern. In clinical reality, especially with chronic conditions, multiple organs are typically involved. Understanding how organs affect each other (like Liver overacting on Spleen, or Kidney failing to support Lung) is essential for effective treatment.
"Zangfu diagnosis alone is sufficient." While Zangfu pattern identification is foundational, it works best when integrated with Eight Principles differentiation (to classify the overall nature of imbalance) and consideration of Qi, Blood, and Body Fluids. These frameworks complement rather than replace each other.
