In ancient China, sailors chewed ginger root to prevent motion sickness and modern studies have confirmed that ginger prevents nausea and vomiting. Danish scientists at Svendborg Hospital observed 80 naval cadets in heavy seas and found that those who took ginger experienced 72 percent less seasickness than a placebo group. Take a 1-gram capsule of powdered ginger root about an hour before you embark, and another every two hours or as needed (without exceeding 10 grams a day) during a journey, Ginger's only side effect is occasional minor heartburn.
