Which organ is considered the origin of body fluids in Traditional Chinese Medicine?

In Traditional Chinese Medicine (TCM), the origin of body fluids is attributed to the function of the Stomach. The Stomach is responsible for the initial transformation and transportation of food and drink, which are essential for the production of body fluids. It functions as a central hub in the digestive process, where ingested substances are broken down and turned into nutrients, including body fluids like saliva, gastric juices, and other secretions that maintain hydration and facilitate bodily functions.

In TCM, the Stomach not only digests food but also helps in the distribution of fluids throughout the body. It works closely with the Spleen, which is responsible for the extraction of Qi and nourishment from the food processed by the Stomach. Together, these organs play vital roles in fluid regulation, providing the necessary nourishment while also contributing to the balance and harmony within the body.

The other organs listed have important functions, but they do not primarily serve as the origin of body fluids in TCM. The Kidney, for example, is associated with the storage of Essence and the regulation of water metabolism, but it does not initiate the production of body fluids from food and drink. Understanding the specific roles of these organs is crucial for grasping the holistic approach of TCM in
