In a double-blind randomized placebo trial, the effect of the powdered rhizome of ginger (Zingiber officinale) was tested on seasickness. Eighty naval cadets, unaccustomed to sailing in heavy seas reported during voyages on the high seas, symptoms of seasickness every hour for 4 consecutive hours after ingestion of 1 g of the drug or placebo. Ginger root reduced the tendency to vomiting and cold sweating significantly better than placebo did (p less than 0.05). With regard to vomiting, a modified Protection Index (PI) = 72% was calculated. Remarkably fewer symptoms of nausea and vertigo were reported after ginger root ingestion, but the difference was not statistically significant. For all symptom categories, PI = 38% was calculated.
在一项双盲随机安慰剂试验中，对姜（姜科植物姜的根茎）粉治疗晕船的效果进行了测试。80名不习惯在波涛汹涌的大海中航行的海军学员在公海航行期间，在摄入1克药物或安慰剂后连续4小时每小时报告晕船症状。生姜根茎比安慰剂更能显著降低呕吐和冷汗的倾向（p小于0.05）。关于呕吐，计算出修正保护指数（PI）=72%。摄入生姜根茎后报告的恶心和眩晕症状明显较少，但差异无统计学意义。对于所有症状类别，计算出PI = 38%。
