Which organ is known as the minister of the water pathway?

The kidney is referred to as the minister of the water pathway in traditional Chinese medicine. This designation highlights its pivotal role in regulating the body's water metabolism and maintaining fluid balance. The kidneys are responsible for filtering blood, removing waste, and managing electrolyte levels, which are crucial for proper hydration and overall health.

In TCM, the kidneys are believed to play an essential role in the storage of vital essence (Jing) and governing the flow of water throughout the body. The connection between the kidneys and water regulation underscores their function in sustaining life and health over time. Thus, the kidney's association with the water pathway reflects its critical position in ensuring the body's fluids are appropriately maintained and balanced.
