this is a good book. own it and is one of my favs. got me started making my own remedies. has all the info one woud need or want.There is a book [on my list of those to purchase, not just check out from the library] called "The Herbal Medicine Maker's Handbook: A Home Manual" by Green. It covers growing, harvesting, and using herbs in teas, infusions, etc., so you know not only which ones, but what to do with them once you have them.
