Mild-to-moderate nausea and vomiting of pregnancy affects up to 80% of all pregnancies. Concern about antiemetic use and the time-limited nature of symptoms has restrained the development of effective treatment approaches, yet supportive, dietary, and lifestyle changes may be ineffective. This article reviews 4 recent well-controlled, double-blind, randomized clinical studies that provide convincing evidence for the effectiveness of ginger in treating nausea and vomiting of pregnancy. It also provides a dosage update for the various forms of ginger.
