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. <a href="

[1]</a> In theory, ginger with large amounts of calcium may increase the risk of abnormal heart rhythms. Study results suggest that dietary phytochemicals, such as capsaicin, curcumin, and resveratrol, have inhibitory effects on P-glycoprotein and potencies to cause drug-food interactions.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> In theory, ginger may increase the risk of bleeding when taken with herbs and supplements that are believed to increase the risk of bleeding (although clear human evidence is lacking).<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> In theory, ginger may increase the risk of bleeding when taken with blood-thinners (although clear human evidence is lacking). Some examples include aspirin, anticoagulants such as warfarin (Coumadin®) or heparin, anti-platelet drugs such as clopidogrel (Plavix®), and non-steroidal anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a>
There is evidence that ginger may increase stomach acid production. It theoretically may work against the effects of antacids, sucralfate (Carafate®), or anti-reflux medications such as H-2 blockers like ranitidine (Zantac®) or proton pump inhibitors like lansoprazole (Prevacid®). Other laboratory and animal studies report that ginger may act to protect the stomach.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Because ginger can theoretically lower blood sugar levels, it may interfere with the effects of insulin or diabetes medications that are taken by mouth.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> In theory, large doses of ginger may increase the effects of medications that slow thinking or cause drowsiness.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> 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.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Ginger may also interact with herbs or supplements taken for nausea/vomiting, pain, arthritis, blood disorders, high cholesterol, high/low blood pressure, allergies (antihistamines), cancer, inflammation, vasodilators, or weight loss.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Ginger may interact with herbs broken down by the liver or with xanthine oxidase herbs.<a href="

http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Additional research is needed to determine the safety and effectiveness of ginger during pregnancy before it can be recommended for longer periods of time.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Some publications discourage large doses of ginger during pregnancy due to concerns about mutations or abortions.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Many experts and publications suggest that ginger powder, tablets, or capsules or freshly cut ginger can be used in doses of 1 to 5 grams daily, by mouth, divided into smaller doses.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Many publications note that the maximum recommended daily dose of ginger is 4 grams. It is believed that the mild stomach upset sometimes caused by ginger may be reduced by taking ginger capsules rather than powder.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Ginger is traditionally said to reduce blood sugar levels at high doses, but there is a lack of scientific evidence available.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Ginger is used orally, topically, and intramuscularly for a wide array of other conditions, without scientific evidence of benefit.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> There is insufficient scientific evidence to recommend the use of ginger in children.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> There is limited scientific evidence in this area, and it is not clear if ginger is beneficial.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a>
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.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Ginger has been suggested as a possible weight loss aid, but more study is needed to a make a firm recommendation.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> In one study, two of eight participants reported an intense urge to urinate 30 minutes after ingesting ginger. Ginger has also been associated with pinkeye (conjunctivitis), but this was considered a rare occurrence.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Irritation or bad taste in the mouth, heartburn, belching, bloating, gas, and nausea have been reported, especially with powdered forms of ginger.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> The most commonly reported side effects of ginger involve the stomach and intestines.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a>
Caution is advised when taking ginger with herbs or supplements that affect the immune system, due to possible interactions.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Common forms of ginger include fresh root, dried root, tablets, capsules, liquid extract, tincture, and tea.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a>
In theory, ginger can cause abnormal heart rhythms, although reports in humans are lacking.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> There are several reports that fresh ginger that is swallowed without enough chewing can result in blockage of the intestines.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a>
Ginger may inhibit platelet aggregation/decrease platelet thromboxane production, thus theoretically increasing bleeding risk.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a> Ginger may theoretically prevent blood clotting by preventing the clumping of platelets. In one study, gingerol compounds and their derivatives were shown to be more potent anti-platelet agents than aspirin. This raises a concern that individuals who are treated with medications that slow blood clotting or who undergo surgery may have a high risk of excessive bleeding if they take ginger supplements.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-ginger.html" TARGET="_blank"
[1]</a>
