Background

The rhizomes and stems of ginger have assumed significant roles in Chinese, Japanese, and Indian medicine since the 1500s. The oleoresin of ginger is often contained in digestive, antitussive, antiflatulent, laxative, and antacid compounds.

There is supportive evidence from one randomized controlled trial and an open-label study that ginger reduces the severity and duration of chemotherapy-induced nausea/emesis. Effects appear to be additive to prochlorperazine (Compazine®). The optimal dose remains unclear. Ginger's effects on other types of nausea/emesis, such as postoperative nausea or motion sickness, remain indeterminate.

Ginger is used orally, topically, and intramuscularly for a wide array of other conditions, without scientific evidence of benefit.

Ginger may inhibit platelet aggregation/decrease platelet thromboxane production, thus theoretically increasing bleeding risk.

Evidence

DISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Nausea and vomiting of pregnancy (hyperemesis gravidarum): Early studies suggest that ginger may be safe and effective for nausea and vomiting of pregnancy when used at recommended doses for short periods of time. Some publications discourage large doses of ginger during pregnancy due to concerns about mutations or abortions. Additional research is needed to determine the safety and effectiveness of ginger during pregnancy before it can be recommended for longer periods of time.
Grade: B

Anti-platelet agent: One study suggested that ginger may have a synergistic effect on anti-platelet aggregation in patients with high blood pressure when used in combination with nifedipine. More study is warranted in this area.
Grade: C

Migraine: There is not enough available scientific evidence in this area.
Grade: C

Motion sickness / seasickness: There is mixed evidence in this area, with some studies reporting that ginger has no effect on motion sickness, and other research noting that ginger may reduce vomiting (but not nausea). Before a recommendation can be made, more studies are needed comparing ginger to other drugs used for this purpose.
Grade: C

Nausea (due to chemotherapy): Initial human research reports that ginger may reduce the severity and length of time that cancer patients feel nauseous after chemotherapy. Other studies show no effects. Additional studies are needed to confirm these results and to determine safety and dosing. Numerous prescription drugs are highly effective at controlling nausea in cancer patients undergoing chemotherapy, and the available options should be discussed with the patient's medical oncologist.
Grade: C

Nausea and vomiting (after surgery): Some human studies report improvement in nausea or vomiting after surgery if patients take ginger before surgery. However, other research shows no difference. Additional studies are needed before the use of ginger before surgery to help with nausea and vomiting can be recommended.
Grade: C

Osteoarthritis: Ginger has been studied as a possible treatment for osteoarthritis. However, results of these studies are mixed. More research is needed in this area.
Grade: C

Rheumatoid arthritis: There is limited scientific evidence in this area, and it is not clear if ginger is beneficial.
Grade: C

Urinary disorders (post-stroke): It is unclear if ginger can help treat urinary disorders in patients recovering from strokes.
Grade: C

Shortening labor: There is not enough available scientific evidence in this area.
Grade: C

Weight loss: Ginger has been suggested as a possible weight loss aid, but more study is needed to a make a firm recommendation.
Grade: C
