Taking ginger for nausea and vomiting during pregnancy

Question. Many of my patients prefer to use natural or herbal medicines, such as ginger, before taking drugs to treat nausea and vomiting of pregnancy. Is there evidence that ginger is safe to use during pregnancy? Is it effective? Answer. Although ginger is used in many cultures to treat the symptoms of nausea and vomiting, no trials have established its safety for use during pregnancy. On the other hand, its efficacy has been documented in two randomized, blinded controlled trials.
