Ginger: Science and Safety

https://www.nccih.nih.gov/health/ginger?nav=govd Background Ginger is native to the warm parts of Asia and is now grown in parts of South America, Africa, and the Middle East as well. Its rhizome (underground stem) is used in food and for health purposes. Ginger is promoted for nausea and vomiting, osteoarthritis, menstrual cramps, and other conditions. What Have We Learned? Ginger dietary supplements may be helpful for nausea and vomiting associated with pregnancy. However, it’s uncertain whether ginger is helpful for nausea and vomiting associated with surgery or cancer chemotherapy, and most studies of ginger for motion sickness haven’t shown it to be helpful. Research suggests that ginger dietary supplements might be helpful for reducing the severity of menstrual cramps. Ginger dietary supplements might be helpful for knee osteoarthritis symptoms, but much of the research has been of poor quality. What Do We Know About Safety? Ginger dietary supplements have been used safely in many research studies. However, ginger can have side effects such as abdominal discomfort, heartburn, diarrhea, and mouth and throat irritation when taken orally. The use of ginger dietary supplements during pregnancy may be safe. As with all herbal supplements, if you’re considering using ginger while pregnant, consult your health care provider.
