It will grow in NC. Just like any state, the conditions need to be right. Right soil, canopy, slope, direction of the sloping etc.
Growing ginseng successfully is a challenge in any state. So if you are going to grow ginseng in NC you will have the same challenges as those growing further north.
To answer part of your question, I would think growing ginseng in the western part of the state would be better than attempting to grow in the eastern part.
However, there may be some nice woods with the right conditions in the eastern part of the state too, so I wouldn't rule the eastern part out totally.
Good luck,
