Having stumbled upon this site lately in my search for wild american ginseng, I would love to buy some of these from you guys but it seems that
1) You cannot export fresh ginseng out of state
2) There seems to be so much red tape to export the dry ones as well that few actually bother with 1/4lb or 1/2lb orders.
Otherwise I don't think its difficult for you to get $400-500/lb for dry ginseng and $150-200/lb for green ones given the rough 3:1 ratio.
