BL25 (Dà Cháng Shū, “Dà Cháng Shū”) is the Back-Shu point of the Bladder Meridian. It is located on the lower back, 1.5 cun lateral to the lower border of the spinous process of the fourth lumbar vertebra (L4). The classical texts locate this point below the sixteenth vertebra. It regulates the intestines, clears damp-heat, alleviates stagnation, strengthens the lumbar spine and legs, and treats conditions of dryness in the Large Intestine.

As the Back-Shu point of the Large Intestine, BL25 is a primary point for any intestinal disorder, effectively treating both diarrhea and constipation by regulating the organ's function. Its location on the lower back also makes it an essential local point for lumbar pain and stiffness, especially when the pain is accompanied by digestive complaints. According to Li Dong-yuan, it is the key point for treating conditions arising from dryness affecting the Large Intestine.
