How to prevent motion sickness - naturally

Did you know that half a teaspoon of ground ginger is more effective than chemical medication in suppressing motion or sea sickness? And unlike most medication, it will not make you drowsy.
Ginger has been used in the Orient for centuries to prevent sea sickness.
Researchers asked subjects who were especially susceptible to motion sickness to sit in a reclining chair that spun around at high speed. All the subjects who ingested a well known medication or who took a placebo experienced violent nausea and/or vomiting.
On the other hand, six of the twelve subjects who took ginger twenty minutes before the test experienced no discomfort. They consumed only 840 milligrams of ground ginger, which is the
equivalent of half a teaspoon. The Japanese have a very curious method of treating all kinds of motion sickness. They use an adhesive plaster to fasten an “umeboshi” (a very salty fermented plum, available in most health food stores in the West) to their navel. The idea may seem a little strange, but what have you got to lose!
