Some of the health benefits of ginger root include relief from mild stomach upsets, reduction of pain caused by osteoarthritis and its ability to help cure or prevent certain onsets of nausea or vomiting caused by non-gastrointestinal causes, as stated by the University of Maryland Medical Center. The UMMC has also noted that ginger root may play a role in preventing heart attacks or strokes. Some studies have shown that ginger root may help prevent clotting and lower cholesterol, but as of 2014,Â it remains uncertain if ginger is an effective or safe treatment for heart disease.
Although there is no scientific evidence to support its effectiveness in humans, the America Cancer Society reported that ginger appears to have shown an ability to slow down or inhibit tumor growth in laboratory animals. The preliminary test results have yet to be fully understood, but the ACS has stated that a possible connection between ginger and tumor prevention deserves further study.
Ginger was shown to be more effective than placebos in trials conducted to measure its effectiveness in treating nausea caused by morning sickness, seasickness and chemotherapy. Regarding motion sickness, it was found that scopolamine achieved better results, but ginger did not produce the side effects that can accompany medications prescribed for motion sickness.
A traditional use of ginger has been to reduce inflammation, and there is evidence that it may help relieve the pain caused by osteoarthritis of the knee. It was also determined that ginger lessened the need for medications such as ibuprofen to relieve the pain caused by osteoarthritis, but the medications appeared to be more effective overall.
