BL-27 - Small Intestine Shu
小肠俞 - Xiǎo cháng shū
Point Region: Lower back
Location & How to Find
Anatomical Location: On the sacrum (the flat bone at the base of the spine), level with the first opening in its back (the first posterior sacral foramen), 1.5 cun out from the central ridge of the sacrum. It is level with BL-31.
Distances are in cun, a unit that scales with each person's body. As a guide, the width of your thumb at its joint is 1 cun, and your four fingers held together, measured across the middle joints, are 3 cun.
How to Locate:
- Find BL-31, in the first hollow in the sacrum
- Move out to the side to two finger-widths from the midline
- The point is there
How to Apply Pressure
Using a fingertip, apply gentle, steady pressure in the first hollow in the back of the sacrum, two finger-widths out from the midline. Firm but never painful pressure is enough; stop if it hurts. Do not press this point during pregnancy. Skip this point over irritated or broken skin.
