What is ginger?
Ginger is a plant that grows in Asia, Africa, and the Middle East. The part used for health is the underground stem (rhizome). It has been used in folk medicine for a very long time.
Today, ginger is sold as a dietary supplement. The FDA does not approve these products before they are sold. This means the rules for making them are less strict than for drugs.
What are the benefits of ginger?
Ginger is used for many health issues. Research shows it may help with nausea and vomiting during pregnancy. It may also help reduce the pain of menstrual cramps.
Studies on other uses are not as clear. It is uncertain if ginger helps with nausea from cancer treatment or surgery. Most studies show it does not help with motion sickness.
Some research suggests it may help with knee osteoarthritis. However, much of that research is of poor quality. Ginger applied to the skin has not been shown to help with knee pain.
