Moxibustion involves burning moxa sticks near an acupuncture point on the little toe, the heat from the stick stimulates the qi in the bladder channel which concentrates on the pelvis and causes very gentle movements of the baby. This is then repeated at home for 20 minutes a day for 10 days, to encourage the baby to turn head down.
This treatment is most successful when completed at 34-36/40 of pregnancy.
