Medical Condition	Uses based on scientific evidence	Grade*
excessive vomiting in pregnancy	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.	b
loss of weight	ginger has been suggested as a possible weight loss aid, but more study is needed to a make a firm recommendation.	c
migraine	there is not enough available scientific evidence in this area.	c
motion sickness	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.	c
nausea alone	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.	c
nausea and vomiting	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.	c
osteoarthrosis unspecified whether generalized or localized	ginger has been studied as a possible treatment for osteoarthritis. however, results of these studies are mixed. more research is needed in this area.	c
other nonspecific findings on examination of urine	it is unclear if ginger can help treat urinary disorders in patients recovering from strokes.	c
rheumatoid arthritis	there is limited scientific evidence in this area, and it is not clear if ginger is beneficial.	c
