Medical research has shown that ginger root is an effective treatment for nausea caused by motion sickness or other illness,[4] and also contains many antioxidants. Powdered dried ginger root is made into capsules for medicinal use. Modern research on nausea and motion sickness used approximately 1 gram of ginger powder daily. Although very effective against all forms of nausea, PDR health officials do not recommend taking ginger root for morning sickness commonly associated with pregnancy, though Chinese women traditionally eat ginger root during pregnancy to combat morning sickness. The Natural Medicines Comprehensive Database (compiled by health professionals and pharmacists), states that ginger is likely safe for use in pregnancy when used orally in amounts found in foods. Ginger ale and ginger beer have been recommended as "stomach settlers" for generations in countries where the beverages are made. Ginger water was commonly used to avoid heat cramps in the United States in the past. Research has also found ginger to be a powerful antioxidant. Ginger has also been shown in research to have a regulatory role in the natural inflammatory response of the body. In India ginger is applied as a paste to the temples to relieve headache.
