Ginger

Ginger (Zingiber officinale) is a plant native to Asia. The ginger spice comes from the roots of the plant. It's used as a food flavoring and medicine.

Ginger contains chemicals that might reduce nausea and swelling. These chemicals seem to work in the stomach and intestines, but they might also help the brain and nervous system to control nausea.

People commonly use ginger for many types of nausea and vomiting. It's also used for menstrual cramps, osteoarthritis, diabetes, migraine headaches, and other conditions, but there is no good scientific evidence to support many of these uses.
