Which organ is considered the king of the zang organs?

In traditional Chinese medicine (TCM), the heart is often referred to as the "king" of the zang organs due to its central role in governing many vital functions. It is considered the most important organ among the zang, as it is responsible not only for the circulation of blood but also for housing the mind or spirit (Shen). The heart’s function is pivotal in maintaining emotional balance, consciousness, and overall vitality.

The heart's significance is further emphasized by its interaction with other organs and systems within TCM. For instance, it influences and is influenced by the lungs, which control the flow of Qi and blood, playing a crucial role in nourishment and support to the heart. Additionally, the health of the heart is paramount for the overall balance in the body, affecting the other organs’ functions.

Understanding the heart's role as the "king" of the zang organs is essential for diagnosing and treating various conditions in TCM, as many disorders can be traced back to imbalances or dysfunctions associated with the heart. This reflects the holistic approach of TCM, where organs are interconnected, and the health of one organ can significantly influence the health of others.
