Chinese culture popularized ginseng as a natural remedy thousands of years ago. It's a pale, gnarly root that grows wild in hilly, wooded areas. The market for wild ginseng has boomed in recent years, rising to around $725 a pound last year. Asian countries like China, Japan, and Korea, are the biggest consumers, and they prefer the wild root for its knobby surface. Kentucky is the nation's number one producer of wild ginseng, but the future of the plant is threatened. Angela Hatton reports.
