Wink,
Welcome to the Wildgrown forums! We hope that you will hang with us and share some future stories of hunting and digging Ginseng, other herbs and maybe even Mushrooms! Don't pass up Mushrooms that are ready for harvest since you will be in the woods looking for Ginseng and other herbs. Some Mushrooms are quite valuable and can be sold on eBay, to restaurants as well as some Ginseng/Herb Dealers. You just have to learn everything you can about them, so that you don't harvest poisonous Mushrooms.
I can answer a couple of questions that you have. Without you having a Dealers License, Ginseng roots must be sold to a Dealer/Buyer that is licensed in your State (i.e. to buy Ginseng harvested in Wisconsin) whether they live in and operate out of Wisconsin or another State. Most other herbs such as Blood Root, Black & Blue Cohosh, Goldenseal (Yellow Root), etc., etc. can be sold to Ginseng/Herb Dealers/Buyers anywhere in the United States. I am sure that as long as the herb pieces (roots, leaves, stems or flowers - whatever portions that are in demand and bought) harvested by you are properly cleaned and prepared (green or dried) for shipment, that Billy Taylor will more than likely purchase them for you. Some of these are wanted and sold/purchased green while some of these must be dried to be sold/purchased. You just need to know what the Buyers want and how they want it!
Good luck and may your hunting and digging ventures be fruitful!
Frank
