Ginger

Human studies suggests that 1g daily of ginger may be effective for nausea and vomiting in pregnant women when used for short periods (no longer than 4 days). Several studies have found that ginger is better than placebo in relieving morning sickness. In a small study of 30 pregnant women with severe vomiting, those who took 1 gram of ginger every day for 4 days reported more relief from vomiting than those who took placebo. In a larger study of 70 pregnant women with nausea and vomiting, those who received a similar dosage of ginger felt less nauseous and did not vomit as much as those who received placebo. Pregnant women should ask their doctor before taking ginger, and should be careful not take more than 1g per day.
