What is the location characteristic of LU-11?

LU-11, also known as Shaoshang, is a point located on the hand, specifically at the radial side of the index finger. The correct characteristic of LU-11 is that it is situated approximately 0.1 cun posterior to the nail of the thumb. This precise location allows for effective stimulation of the Lung meridian, reflecting its function in treating conditions associated with the Lung system, including respiratory issues and clearing heat from the body.

Understanding this specific point's location is essential for proper acupuncture practice, as precision in locating acupuncture points can significantly affect the treatment's efficacy. The measurement of being 0.1 cun posterior to the nail indicates a close proximity to the nail bed, which is crucial for both accessing the point correctly and ensuring that the treatment adheres to traditional acupuncture techniques.
