As the Luo-Connecting point of the Small Intestine channel, Zhizheng is a key point for addressing psycho-emotional disorders stemming from a disturbance in the Heart-Small Intestine relationship, such as mania, fear, and sorrow. Its ability to clear heat and resolve the exterior makes it useful for febrile diseases, especially those with neck stiffness and headache. The classical distinction between treating excess (joint laxity, elbow dysfunction) with drainage and deficiency (warts, scabies) with reinforcement provides a clear diagnostic and therapeutic guideline.
