According to the "Ling Shu," which points should be selected when Yin organs are diseased?

Choosing Yuan Source points when Yin organs are diseased is based on the understanding of Traditional Chinese Medicine and the specific functions associated with these points. Yuan Source points are directly connected to the organ's primary energy and have a significant role in regulating the flow of Qi (vital energy). When a Yin organ is compromised, selecting its corresponding Yuan Source point can help restore balance and support the natural healing processes of that organ.

Yuan Source points are crucial for tonifying the organ’s energy and can be particularly effective for addressing deficiencies or stagnation within the Yin organs. They serve as a way to access the deeper aspect of the organ's energy, promoting restoration and balance in its functions.

The other concepts, while important in their own right, do not offer the same direct connection to restoring Yin organ health. For example, Xi Cleft points are useful for acute conditions and pain management, Luo Connecting points help in communicating between paired organs or resolving imbalance, and Jing Well points primarily focus on issues related to the extremities and consciousness rather than directly treating Yin organ disorders. Thus, for optimal treatment of Yin organ diseases, Yuan Source points are the most relevant choice.
