the pubic symphysis, lateral to the femoral artery.

From the upper border of the pubic symphysis (➞Ren-2),

measure 3.5 cun in a lateral direction. There, you can feel the

pulsation of the femoral artery. SP-12is located in a depression

immediately lateral to the artery.

Located on the same level are Ren-2(on the midline), ➞KID-11

(0.5 cun lateral to the midline) and ➞ST-30(2 cun lateral to the

midline). ➞LIV-12is located 2.5 cun lateral to the midline, but

1 cun inferior to the upper border of the pubic symphysis.

Needling

Vertically 0.5–1 cun. Caution: Needling in a medial direction

may puncture the artery; needling in a lateral direction may

injure the femoral nerve.
