Ginger may help overcome morning sickness

Investigators found that a group of 32 pregnant women who took a daily supplement containing 1 gram of ginger for 4 days reported feeling less nauseous and had fewer vomiting episodes than a group of 35 women who took an inactive placebo pill.

Ginger did not appear to cause any side effects among the mothers or their babies, although more research will be needed to confirm this finding, Dr. Teraporn Vutyavanich and colleagues from Chiang Mai University in Thailand report in the April issue of Obstetrics and Gynecology.

According to the researchers, nausea and vomiting during the first trimester of pregnancy, also known as morning sickness, is common but not well understood. Some studies have suggested that morning sickness indicates that a pregnancy is healthy, because a growing placenta produces estrogen. The hormone can heighten a woman's sense of smell and cause nausea. If the placenta is not producing estrogen, there may be a problem with the pregnancy.
