It is unlikely but possible that you could locate a dealer in Alabama. However, there are quite a few in Tennessee and there could be one located within a reasonable drive from your location. You will have to contact the Department of Agriculture for the State of Tennessee via phone. I called them a few years back and they gave me the Dealers near to my location and will probably do the same for you. It is possible that they would email you a list and you can find the one's closet to you!
As leightonbankes stated, you can only buy Ginseng that has been certified and you normally have to go to a Dealer for that. I believe that there are Dealers that sell certified Wild Ginseng on eBay, so that is another possibility.
You are right Brad! I realized after the fact, that any Ginseng Buyer/Dealer on Wildgrown could sell Xena some Ginseng once it had been certified. I decided not to edit the post and put the information in because I didn't want you Boys to fall all over yourselves trying to get Xena's business and such a pretty Lady's telephone number!
