Researchers interested in acupuncture for morning sickness, have undertaken a network meta-analysis comparing treatments. Acupuncture, acupressure and methylprednisolone for hyperemesis gravidarum, the severe form of morning sickness, offered better therapeutic benefits than standard care. Acupressure also reduced the need for rescue antiemetics.
