I've read also that ginger is good for the inflammation that causes arthritis (among other things). The ancient Romans used it, and Europeans are still using it. Only we seem to have forgotten. Martha Stewart one time recommended taking a 2" piece of ginger, peeling it, slicing it into a small pot of water and boiling it. Then add honey and lemon, if you like, and enjoy. It also calms the queasy stomach. At Hong Kong Market here, I get some soft ginger candies to eat after I've eaten out. They really work.
