Ginger has high mineral content, being a good source of potassium, magnesium, copper, manganese and vitamin B6. They also contain certain compounds like gingerols, shogaols and zingerone, volatile oils that give it its characteristic odor and flavor. These oils have been known to increase gastrointestinal tract motility in laboratory animals and also have antibacterial, antipyretic, analgesic and sedative properties. Studies have also shown that gingerols can kill ovarian cancer cells. When ginger is dried or cooked, shogaols and zingerone are produced from the gingerols, which give it its pungent taste.
