try and see if you have a wiccan store near by or try on line and see what they have i go to one of my local pagan stores and see what they have and they normally have what i am looking for, if you try looking on line you may be able to find out more of what the herbs are for and talk to pagans in your area if you can find some...

good luck

I personally grow as many as I can, but if I can't then I try health food stores. :)

Ive been trying to figure out the same thing! Living here in Pa seems like a complete different world from everywhere else Ive traveled to. We have no cultural store near me at all that I know of. Unless you grow it yourself you have to get it a regular grocery store. Ive been lucky enough to have the room in our yard/house to grow different things. Roaring Spring is near Altoona if you have ever heard of it? Where are you at in Pa?
