Commentary
Wushu GB-27 is similar to Daimai GB-26 in function. Both points is able to regulate Girdle Vessel, so as to treat leucorrhoea, menstruation problems or pain in the lower abdomen.
However, GB-27 is more on treating men with pain (eg: testicle retraction). However, GB-26 is more indicated for gynecological problems.
Classical Sources
Zhenjiu Jiayi Jing (針灸甲乙經): Lists GB-27 for treating hernia, lower abdominal pain, and leukorrhea.
Zhenjiu Dacheng (針灸大成): Records indications including lumbar pain, constipation, and disorders of the lower burner.
Ling Shu: The Dai Mai pathway passes through this point, connecting the Gallbladder channel with the Girdle Vessel to regulate the lower jiao.
How to Locate
First palpate along the upper border of the iliac crest in an anterior and inferior direction so as to identify ASIS (anterior superior iliac spine). ASIS is a bony ridge on the lateral aspect of the lower abdomen. Wushu GB-27 is in a depression medial and anterior to the ASIS.
Caution
Located near the peritoneal cavity. Avoid deep perpendicular needling to prevent peritoneal puncture. Use caution during pregnancy as this point is on the lower abdomen and affects the uterus through Dai Mai regulation. Ensure proper angle and depth control, especially in thin patients.
