BL27 (Xiǎo Cháng Shū, “Small Intestine Shu”) is the Back-Shu of Small Intestine point of the Bladder Meridian. BL27 is found on the sacrum, 1.5 cun lateral to the midpoint between the posterior superior iliac spines, at the level of the first sacral foramen. It regulates the Small Intestine, separates clear from turbid, and resolves dampness.
BL27 is found on the sacrum, 1.5 cun lateral to the midpoint between the posterior superior iliac spines, at the level of the first sacral foramen.
Perpendicular insertion 1.0 to 1.5 cun. Exercise caution to avoid deep insertion, especially in thin patients.
Regulates the Small Intestine, separates clear from turbid, and resolves dampness.
Abdominal pain, diarrhea, dysentery, dysuria, lower back pain.
As the Back-Shu point of the Small Intestine, BL27 is crucial for regulating the Small Intestine's function of separating clear from turbid, making it effective for digestive issues like abdominal distention, diarrhea, and dysentery. It is also used for urinary disorders, reflecting the Small Intestine's role in fluid metabolism. This point is often combined with CV4 (Guanyuan) to address chronic digestive and urinary imbalances.
