need list and price guide of plants

I need a list of, plants , roots, like ginseng ,goldenseal and others that you can hunt in the woods and sell. I also need a price list, does anyone know a website , i have been to so many sites and cant find what i am looking for.

I don't know where you might find a price guide or catalog but, I can tell you this.
Ginseng is a protected species and you have to be liscensed to harvest it and you have to know what you're doing to harvest it.
  Much like Trilium, it grows less like one plant and more like a colony of plants.  They're all interconnected underground by the root system.  You can kill an entire area of growth by harvesting the wrong plant or too many.
  The department of agriculture in your state or Forest service might be of some help with liscencing and harvest infromation.
