What is the classification of GB-36 (wai qiu)?

GB-36, known as Wai Qiu, is classified as a Xi-Cleft point. Xi-Cleft points are located on the channels where significant Qi and blood are concentrated, and they are particularly effective for acute conditions and pain. They serve to alleviate sudden onset issues, making them valuable for treating conditions related to the organs or tissues associated with that meridian.

In the case of GB-36, being a Xi-Cleft point means it plays a critical role in addressing any problems that may be reflected in the Gallbladder channel, especially those that arise suddenly or are characterized by pain. This classification helps practitioners understand its functional significance and how to use it effectively in treatments.

The other classifications suggested in the choices do not align with the established definitions of GB-36. While various points serve different purposes within the system of Traditional Chinese Medicine, the defining aspect of GB-36 as a Xi-Cleft point is crucial for channeling therapeutic interventions effectively.
