Which acupuncture point is situated 1.5 cun lateral to T4?

The acupuncture point located 1.5 cun lateral to T4 is BL-14, not BL-15. BL-14, also known as "Jueyin Back Shu," is accurately positioned at this measurement. The definition of “cun” is a unit of measure used in acupuncture to determine distances between points on the body, typically relating to anatomical landmarks like vertebrae.

Understanding this specific location is important for practitioners, as precise acupuncture point placement is critical for effective treatment. BL-15, known as "Xin Shu," is located 1.5 cun lateral to T5, which is not the correct distance you are looking for as per the question asked. Thus, when performing acupuncture, identifying the correct vertebral levels and their corresponding points is vital to ensure the effectiveness of the treatment being administered.
