Pregnant, with morning sickness? Behold the power of ginger. Based on the evidence so far, ginger seems safe and more effective than sugar pills at relieving nausea and vomiting during pregnancy. Ginger comes in many forms—including syrups, capsules, and powders. Moms-to-be with morning sickness typically take ginger three or four times a day, with a total daily dose of about 1 gram.
