What organ is considered the ruler among other organs in the Chinese medical system?

In traditional Chinese medicine, the heart is referred to as the "ruler" among the organs due to its central role in maintaining overall health and harmony within the body. The heart is viewed as the organ that governs blood circulation and houses the mind or spirit, known as the "Shen." This dual function highlights its importance not only in physical health but also in mental and emotional well-being.

The heart's association with the regulation of blood flow means it has a significant influence on nourishing the other organs and tissues. It also establishes a connection between physical vitality and emotional stability. As such, imbalances or disharmonies involving the heart can lead to widespread implications for health in other areas of the body.

Understanding the heart’s crucial role helps in the application of holistic treatment approaches in Chinese medicine, where the interconnectedness of bodily functions is emphasized. This enables practitioners to focus on both the physiological and psychological aspects of a patient's health, promoting comprehensive care.
