Moxibustion! Vas, Aranda, Nishinya et al., Correction of nonvertex presentation with moxibustion: A systematic view. American Journal of Obstetrics & Gynecology (2009): 201 (3), 241-59.
“Moxibustion involves burning the herb mugwort (Artemisia vulgaris) over an acupuncture point found on the outer corner of the smallest toenail. Seven studies presenting data from 1087 women were included in the analysis. All the women in the studies in this review were randomly picked to receive either moxibustion or one of the other methods, to strengthen confidence that any differences in experiences of study groups were due to the moxibustion.
Combined results from the studies showed that the fetuses of women receiving moxibustion were 36% more likely to turn to a head-first position than those who got other treatments or no treatment, and this result was statistically significant. To check this result, the study authors looked separately at four trials that used similar starting points for moxibustion, all after the 32nd week of pregnancy. Here too, the likelihood of the fetus turning to a head-first position was more than 30% greater for the women who got moxibustion than for those who got another treatment. The study found no differences in safety between moxibustion and the other methods.” Full article here
