What is the main function of the Spleen in traditional Chinese medicine (TCM)?

In traditional Chinese medicine (TCM), the main function of the Spleen is indeed transforming and transporting food and fluids. The Spleen is integral to digestion, as it is responsible for converting the nutrients derived from food into Qi (vital energy) and Blood. This transformation happens through the process of digestion, where ingested food is processed into usable forms of energy for the body. Moreover, the Spleen plays a crucial role in the transportation of these nutrients throughout the body, ensuring that they reach the necessary organs and tissues.

In addition to its digestive functions, the Spleen is also involved in maintaining fluid balance within the body, preventing dampness and phlegm accumulation, which are often associated with Spleen deficiency. Thus, the importance of the Spleen's ability to transform and transport food and fluids underscores its foundational role in overall health and well-being in TCM. Understanding this primary function is critical for diagnosing and treating various conditions related to Spleen deficiency, such as fatigue, bloating, and loose stools.
