Acupressure Points for Labor Induction: Evidence, Technique & Safety
Acupressure may support cervical ripening and labor onset when used at term (≥39 weeks) under provider guidance. It is not a substitute for medical induction when indicated.
Key Points with Proposed Mechanisms
| Point | Location | TCM Function | Proposed Mechanism |
|---|---|---|---|
| SP6 (Sanyinjiao) | Medial leg, 4 finger-widths above medial malleolus, posterior tibial border | Tonifies Spleen/Kidney/Liver; regulates Chong/Ren vessels | Uterine contractility via pelvic nerve reflexes; prostaglandin release |
| LI4 (Hegu) | Dorsal hand, 1st web space, radial midpoint of 2nd metacarpal | Moves Qi/Blood; opens orifices | Oxytocin release (hypothalamic); analgesic (gate control) |
| BL32 (Ciliao) | 2nd posterior sacral foramen (dimples above buttocks) | Regulates Bladder channel; benefits uterus/bladder | Sacral nerve root stimulation (S2–S4) → uterine contractility |
| BL60 (Kunlun) | Posterior to lateral malleolus, in depression between malleolus & Achilles | Relaxes sinews; descends Qi | May promote cervical ripening; contraindicated pre-term |
| KI1 (Yongquan) | Sole, junction of anterior 1/3 & posterior 2/3, on midline | Descends Kidney Qi; grounds Yang | Relaxation, ↓ sympathetic tone → favorable for labor onset |
| GB21 (Jianjing) | Midpoint of upper trapezius, halfway between C7 & acromion | Descends Qi; induces labor | Reflex uterine stimulation; contraindicated pre-term |
