How to relieve motion sickness?

Source of information : TV programme I had always suffer from motion sickness. Used to rely on medicine but sometimes I would forget to bring the medicine along. Saw on the TV programme that some natural food actually work very well when its been experiment on students that suffer from the same problem.

Ginger pill or ginger tea

Lemon slices

According to the expert in the show, motion sickness is caused by our eye and ear is sending difference signal towards our brain. The eye see no motion but the balancing drums in our ear is telling the brain that we are having hugh motion difference. The brain being the most intelligence system analyse that difference and conclude we are suffering from poisoning and thus combat the system by evoking vomitting command.

Taking lemon slices or ginger stops the signal sent to the brain and stop the confusion.

I shall try this on my next trip.
