Ginger root is extracted and made into tablet form. Active ingredients include gingerols (which give ginger its flavor and odor) and shogaols.


Ginger is said to be an effective antiemetic and antinauseant, especially for nausea caused by motion sickness or pregnancy, and to relieve intestinal cramps. Ginger is also used as an anti-inflammatory and analgesic. It may have antibacterial properties and antiplatelet effects in vitro, but data are inconsistent. Scientific studies are consistent with a beneficial effect in pregnancy-related nausea and vomiting.

Adverse effects

Ginger is usually not harmful, although some people have a burning sensation when they eat it. Nausea, dyspepsia, and dysgeusia are possible. Theoretically, ginger is contraindicated in patients who have bleeding diatheses or who take antiplatelet drugs or warfarin.
