My wife, Janet, used to have a big knot on her knuckle and a sore foot caused by arthritis. Somewhere she read about drinking Green Tea to help with arthritis problems. So she started having a cup every morning with breakfast. The knot has gone away and so has her foot pain. This didn't happen over night -- it's no "snake oil" treatment. It took a couple of months or so for relief. But she did get relief.
