Therapeutic uses and scientific validation

One randomized controlled trial studied a classical TCM treatment for breech birth (i.e., buttocks-first orientation of the baby, which is much riskier than head-first). The study showed that moxibustion at acupoint BL 67 (aka UB 67), located at the tip of the fifth toe, reduced the need for external cephalic version compared to placebo and decreased the use of oxytocin for women who had vaginal deliveries.^[1]
