I personally use 500 mg. It works on the digestive process, removing toxins that exacerbate the inflammatory process in joints. The Aruvedic belief is that if digestion doesn't work well, it leads to impurities in our body. Those impurities travel in the bloodstream and they end up in joints and in bones, which causes the arthritis. No one knows exactly how ginger root works in our system but it is very inexpensive and it is easy to take, and there are no side effects.
Ginger root is also good for preventing and treating balance problems and dizziness.
People who are older tend to have problems with balance and dizziness because of changes in their vestibular system, their eyesight, and musculoskeletal system. I will often prescribe ginger root to an older person to take twice a day. At worst it's a digestive aid and at best it might actually eliminate some of their arthritis symptoms and maintain balance, and thus prevent falls. It is important also to stay away from fried food, margarine, and produce with insecticides, as free radicals associated with these foods may exacerbate the inflammatory process in the body.
