Ginger is a flowering plant that originated in Southeast Asia. It’s among the healthiest (and most delicious) spices on the planet.
The rhizome (underground part of the stem) is the part commonly used as a spice. It’s often called ginger root or, simply, ginger.
Ginger can be used fresh, dried, powdered, or as an oil or juice. It’s a very common ingredient in recipes. It’s sometimes added to processed foods and cosmetics.
Ginger has a very long history of use in various forms of traditional and alternative medicine. It’s been used to aid digestion, reduce nausea, and help fight the flu and common cold, to name a few of its purposes.
