Ginger Root
Historically, ginger has a long tradition of being very effective in alleviating discomfort and pain in the stomach. Ginger root has been anecdotally reported to reduce the symptoms associated with motion sickness including dizziness, nausea, vomiting and cold sweating.
Ginger also contains very potent anti-inflammatory compounds called gingerols. These substances are believed to explain why so many people with osteoarthritis or rheumatoid arthritis experience reductions in their pain levels and improvements in their mobility when they consume ginger regularly.

How to choose
Go for the plump blemished roots. Avoid wrinkled roots, as they're likely to be tough and fibrous. If possible, avoid any that are very knobbly, as they'll be harder work to peel. Roots should also feel heavy for their size.
