Is American Ginseng supposed to be a cooling herb or warming herb?

Can you answer jumpinjack’s question about Ginseng?:

I read everywhere that American Ginseng is a cooling herb that helps tonify the lungs, yet when I take American Ginseng, my hands and feet that are usually cold become warm…. how is that possible?….and btw, does American Ginseng have Laxative effects?
