The literature assessing the safety and efficacy of the use of ginger (not specified) to treat nausea and vomiting in pregnancy was reviewed. Various doses and forms of ginger were used to treat women during their first and second trimesters of pregnancy. Ginger improved the symptoms of nausea and vomiting compared with placebo in pregnant women. Data were insufficient to recommend ginger universally and there are concerns with product quality due to limited regulation of dietary supplements.
