What type of organs are considered Yang organs?

Yang organs are classified primarily as hollow organs in traditional Chinese medicine. This classification is based on their physiological functions and characteristics. Yang organs, such as the stomach, intestines, bladder, and gallbladder, are responsible for the processing, transformation, and transportation of substances within the body. They play a crucial role in digesting food, absorbing nutrients, and excreting waste, indicating a dynamic and active nature—qualities that are representative of Yang energy.

In contrast to solid organs, which are often associated with storing substance and are termed Yin organs, Yang organs are more about the movement and flow within the body. Their hollow structure allows for the storage and passage of fluids and waste, highlighting their functional role in maintaining balance within the body's system. Understanding this distinction is fundamental in acupuncture and traditional Chinese medicine practice, as treatment often focuses on the functions and interactions of these organs to restore health and balance.
