In a double-blind, randomized, crossover trial, 1 g of ginger was administered daily for 4 days. The preference among the patients to receive ginger versus placebo was significant.12 Concurrently, the relief of nausea and vomiting found with the use of ginger compared with placebo was significantly greater. In a study by Vutyavanich and associates,20 1 g of ginger was given to women with hyperemesis for 4 days, and two measuring scales were implemented to quantify patients’ nausea.20 The improvement in the nausea scores of patients receiving ginger was significantly greater than that of the placebo group. Also, after 4 days of treatment, there was a significant decrease in vomiting in the gingertreated group versus the placebotreated group.20 However, different collections of ginger may differ due to their growing climates, conditions, and harvesting times.20 There have been no teratogenic effects of ginger in this or other studies.12
