Ginger is a flowering plant that originated from China.
It belongs to the Zingiberaceae family, and is closely related to turmeric, cardomon and galangal.
The rhizome (underground part of the stem) is the part commonly used as a spice. It is often called ginger root, or simply ginger.
The unique fragrance and flavor of ginger come from its natural oils, the most important of which is gingerol.
Ginger can be used fresh, dried, powdered, or as an oil or juice, and is sometimes added to processed foods and cosmetics. It is a very common ingredient in recipes.
