Ginger

A centuries-old folk remedy, ginger, is widely used to treat nausea despite the fact that no one really knows exactly how it works.  Scientists suspect phytochemicals may play a role in quieting an unsettled stomach. But the how of things might not seem so important in light of studies that find taking ginger in tandem with anti-nausea meds can help wipe out, or at the very least minimize, nausea during chemotherapy. The protective dose: ½ to 1 gram powdered ginger, which is about the equivalent of 1/4 to 1/2 teaspoon fresh.
