From what I've read about others actually involved on ginseng collection, the "large monetary yields" are simply television hype. There are no rich Ginseng hunters/growers in the real world. That's not to say you can't actually sell it, but don't expect it to give you a "get rich" kinda crop.
What is that? Is that a mongol horde? Can we fend them off with this tiny ad?
