‘Wǔ zàng’ literally means ‘five viscera’ and refers to the heart, liver, spleen, lungs, and kidneys — a foundational concept in Traditional Chinese Medicine (TCM). Unlike Western anatomy, which views organs primarily as physical structures, TCM understands the wǔ zàng as functional systems that govern emotions, bodily processes, and energetic balance. Each organ is associated with a specific element (e.g., wood for liver, fire for heart), season, emotion, and sensory organ.

The term appears frequently in health-related discussions, herbal medicine, acupuncture theory, and wellness advice. It’s rarely used in everyday casual speech but is common in medical contexts, health articles, or when describing holistic well-being. While ‘zàng’ alone can mean ‘viscera’ or ‘organ’, the compound ‘wǔ zàng’ always refers specifically to this classical set of five — never to modern anatomical listings or arbitrary groupings.
