Visceral Manifestation [Zang-Xiang]
Visceral manifestation theory (Zang-Xiang) is the core of the TCM theoretical system. Using the methodology of “inspecting the exterior to infer the interior,” it studies the morphology, physiological functions, pathological changes, and interrelationships of the zang-fu organs, and explains their holistic connections with the body, sensory orifices, emotions, fluids, and the external environment. It is the systematic theory through which Chinese medicine understands human physiology and pathology, providing the theoretical foundation for clinical pattern differentiation and treatment.
Visceral manifestation theory (Zang-Xiang) is a doctrine that primarily employs methods such as “inspecting the exterior to infer the interior” (si wai chuai nei) — assessing the internal zang-fu organs by observing their outward manifestations. On the basis of studying the morphological structure of the body's zang-fu organs, the theory centers on investigating their physiological functions, pathological changes, and mutual interconnections, while also examining the relationships between the organs and the body, the sensory orifices, emotions, body fluids, and the external environment. It is a systematic theory unique to Chinese medicine regarding human physiology and pathology, the core content of the TCM theoretical system, and the theoretical foundation for pattern differentiation and treatment across all clinical specialties.
