Explanation by: Ruchi Sharma

Motion sickness or kinetosis, also known as travel sickness, is a condition in which a disagreement exists between visually perceived movement & the vestibular system's sense of movement. If the motion causing nausea is not resolved, the sufferer will usually vomit. Depending on the cause it can also be referred to as seasickness, car sickness, simulation sickness or airsickness. Ginger is reported to calm the pyloric valve situated at the base of the stomach. This relaxation of the valve allows the stomach to operate normally whereby the contents will enter the small intestine instead of being retained within the stomach. It is this undesirable effect of retention in the stomach that eventually results in vomiting.
