What are the characteristics of Yang organs in TCM?

In Traditional Chinese Medicine (TCM), Yang organs, also known as "fu" organs, are characterized by their hollow nature and their primary role in receiving, processing, and excreting. These organs include the stomach, intestines, bladder, gallbladder, and other systems that engage in the movement and transformation of substances rather than storage.

The nature of these organs means that they are designed to take in food and liquids, digest them, and then either transform them into Qi and blood or eliminate waste. This contrasts with Yin organs, which are solid and are responsible for storing essential substances such as blood, Qi, and essence.

The association of Yang organs with receiving and holding food and water is fundamental to their function in maintaining overall health by facilitating digestion and ensuring proper elimination, thus supporting the body’s metabolic processes. Understanding this characteristic helps clarify the vital roles these organs play in the greater context of TCM diagnostics and treatment approaches.
