What is true regarding the classification of the SI-18 acupuncture point?

The SI-18 acupuncture point, also known as "Quanliao," is classified as a Meeting Point. Specifically, SI-18 serves as a meeting point for the Small Intestine, Triple Warmer, and Gall Bladder meridians. Meeting Points are significant because they connect the associated channels and can influence the flow of energy (Qi) in the areas that those channels govern. This makes SI-18 particularly useful in treating conditions that involve the interplay of these three meridians, such as facial disturbances or issues related to the eyes and ears, which are areas influenced by these channels.

In understanding the classifications of acupuncture points, it's important to recognize that the other options presented do not accurately describe SI-18. Jing River points relate to the flow of Qi and can be particularly effective for treating disorders of the voice and respiratory issues, while Luo Connecting points have a specific role in connecting the main channel with its branch, often associated with the most proximal points. He Sea points are associated with lower body issues and have different therapeutic implications. Therefore, the classification of SI-18 as a Meeting Point is what distinguishes its function and clinical significance within acupuncture practice.
