What is the significance of SJ-22 acupoint?

SJ-22, also known as "Erhel," holds particular significance as an exit point in Traditional Chinese Medicine (TCM) and acupuncture practice. Exit points are locations on the meridian that are believed to facilitate the flow of Qi (energy) out of the channel and are directly related to the communication between the meridian and the exterior. In the case of the San Jiao channel, SJ-22 helps to disperse Qi and can be effective in treating conditions related to the head, ear, and facial regions.

Understanding the role of SJ-22 as an exit point is fundamental for practitioners, as it not only aids in various treatment strategies but also enhances the understanding of the overarching theory of flow within the meridian system. Recognizing this acupoint's function allows acupuncturists to utilize it effectively in clinical scenarios involving issues such as headaches, tinnitus, and other conditions that require the release of excess energy or blockage in the San Jiao channel.
