Which organ is said to rule the entire body?

The heart is often considered the organ that rules the entire body in Traditional Chinese Medicine (TCM). This perspective is grounded in the concept of the heart being the center of the circulatory system and, symbolically, the seat of consciousness, emotions, and spirit, known as "Shen." In TCM, the heart not only plays a crucial role in the physical pumping of blood but is also associated with mental clarity, emotional balance, and overall vitality.

The heart governs blood and houses the mind, making it essential for maintaining the harmony of the body's multiple systems. The health of the heart influences other organs and systems in profound ways, highlighting its ruling status. All these factors contribute to the belief that the heart holds a superior role in governing the overall health and functionality of the body in TCM philosophy.
