Where is GB-1 located?

GB-1, also known as "Tongziliao," is located at the outer canthus of the eye. Specifically, it is positioned 1/2 cun lateral to the outer canthus, making it a key point along the Gallbladder meridian that is used in treatments related to eye disorders, facial pain, and more.

The anatomical placement of GB-1 is significant as it links the Gallbladder channel to facial and ocular issues. This location helps in facilitating the flow of Qi and blood in the region and provides therapeutic benefits for conditions affecting the eye and surrounding areas, such as eye pain or excessive tearing.

The other options do refer to locations that correspond to acupuncture points but do not correctly identify the location of GB-1. For instance, 1 cun anterior to the upper border of the ear and 1 cun superior to GB-12 refer to different points entirely, while directly alongside SJ-17 relates to the position of another acupoint associated with the Sanjiao meridian. Understanding the precise placement of GB-1 is crucial for effective acupuncture practice and treatment.
