Where is the Back Shu point BL-25 located?

The Back Shu point BL-25 is located 1.5 cun lateral to the fourth lumbar vertebra (L4). This point is associated with the large intestine and is used to influence its function by accessing the corresponding organ system through the back Shu points.

In the context of acupuncture and Traditional Chinese Medicine, the Back Shu points are significant as they are linked to the internal organs and provide deep access to the organ's energy, or qi. BL-25, in particular, plays a role in managing conditions related to the large intestine, such as digestive issues or lower back pain.

The anatomical reference of BL-25 being 1.5 cun lateral to L4 relates to the standard practice in acupuncture of measuring distance based on the patient's body. The lumbar region is crucial for both structural stability and organ function, making this point particularly relevant for practitioners focusing on lower abdominal and spinal health. Therefore, the specificity of the location enhances the precision of treatment strategies associated with large intestine pathologies.
