pregnant girlMoxibustion (burning of mugwort) near the classic point for version of a breech presentation leads to 58%  vertex presentation at birth as opposed to 43% of pregnant women who had non-specific moxabustion.  Well powered study of 406 healthy pregnant women.   Nice!  Their conclusion

“Moxibustion at acupuncture point BL67 is effective and safe to correct non-vertex presentation when used between 33 and 35 weeks of gestation.”

OBJECTIVE:

To compare the effectiveness of additional moxibustion at point BL67 with moxibustion at a non-specific acupuncture point and with usual care alone to correct non-vertex presentation.
METHODS:

This was a multicentre randomised controlled trial in which 406 low-risk pregnant women with a fetus in ultrasound breech presentation, with a gestational age of 33-35 weeks, were assigned to (1) true moxibustion at point BL67 plus usual care; (2) moxibustion at SP1, a non-specific acupuncture point (sham moxibustion) plus usual care; or (3) usual care alone. The primary outcome was cephalic presentation at birth. Women were recruited at health centres in primary healthcare.
RESULTS:

In the true moxibustion group, 58.1% of the full-term presentations were cephalic compared with 43.4% in the sham moxibustion group (RR 1.34, 95% CI 1.05 to 1.70) and 44.8% of those in the usual care group (RR 1.29, 95% CI 1.02 to 1.64). The reduction in RR of the primary outcome in women allocated to the true moxibustion group compared with the usual care group was 29.7% (95% CI 3.1% to 55.2%) and the number needed to treat was 8 (95% CI 4 to 72). There were no severe adverse effects during the treatment.
CONCLUSIONS:

Moxibustion at acupuncture point BL67 is effective and safe to correct non-vertex presentation when used between 33 and 35 weeks of gestation. We believe that moxibustion represents a treatment option that should be considered to achieve version of the non-vertex fetus.
