UB 27 Acupuncture Point Applications and Theory

The acupuncture point "UB 27" , 小腸俞, is represented by "Xiao Chang Shu" in pinyin and "Small Intestine Shu" in english and may be found:

1.5 cun lateral to GV line, level with 1st PSF.


Of many possible clinical applications, it may be considered to influence the following issues/symptoms:

  • Main point for all Small Intestine related issues.
  • Damp heat effecting the bladder (difficult or painful urination, hematuria, dark urine).
  • Damp heat effecting the intestines (diarrhea, hemorrhoids, dysentary).
  • Other lower warmer discharges - leukorrhea, seminal emission.

A single acupuncture point is not commonly thought of as an empirical way to influence a TCM diagnostic pattern. UB27, however, is a strong candidate to be incorporated into an acupuncture protocol for patients who exhibit: Bladder Damp Heat and/or Large Intestine Damp Heat

UB 27 may potentially be used, in coordination with a well designed acupuncture treatment protocol, to influence the following conditions: Diarrhea, Dysentary, Hemorrhoids, Leukorrhea, Seminal Emission and/or Urinary Disorders (Lin Disease)

While not necessarily valid clinically, EX Huatuojiaji at S1 (S1 influences the ureter and is used along with S…) and UB 31 (UB 31, UB 32, UB 33 & UB 34 together form the…) are nearby.
