2- Ginger (Zingiber officinale)
Ginger is a popular remedy for nausea, as well as post-chemotherapy nausea and morning sickness. Numerous studies have suggested that it is even more effective than Dramamine in the case of motion sickness.
To relieve motion sickness, you should take 500 mg of the powdered extract half an hour before you start the trip, and then every 4 hours until you arrive at the destination.
You can also prepare an infusion, by adding ¼ to 1 gram of ginger to boiling water, leave it to steep for 15 minutes, and drink it three times daily.
Caveats: You should take ginger in food if you are prone to heartburn, and in the case of pregnancy, do not take more than 2 grams daily.
