Ginger is actually the root or rhizome of the Zingiber officinale plant. A fragrant spice, it has a tangy flavor that can leave a bit of heat in the back of the mouth. It is a common ingredient in many Asian dishes, and is also a mainstay in Western sweets and desserts.
Ginger is drunk either as the sole ingredient in ginger tea, or mixed with other tea leaf varieties.
Chewing a bit of ginger offers relief from colds and sore throats. It is also used to ease motion sickness, relieve menstrual cramps, and reduce heartburn.
