Q. Is ginger really good for nausea or is this an old wives' tale?
Ginger is an underground stem that is beige, thick and knotted. The stem extends roughly a foot above ground with long, narrow, ribbed, green leaves, and white or yellowish-green flowers.
The underground stems of the ginger plant are used for cooking and medicinal purposes. In Asia, ginger is used to treat stomach aches, nausea, and diarrhea. Ginger extract is found in many dietary supplements sold in the United States for digestive ailments.
