There are books and references that focus primarily on uses of herbs, and then there are some with a certain turn of phrase or chosen word that capture the magic of herbs as well as their usefulness. Following are some digitalized old herbals, as well as more recent references I hope will be enjoyed:
Rosetta E. Clarkson, Green Enchantment, The Magic Spell of Gardens -
http://babel.hathitrust.org/cg...
Mrs. M. Grieve, A Modern Herbal -
http://botanical.com/botanical... - During WWII, when Germany blockaded England, medical supplies could not get through, so old herbal remedies were resorted to. Herbal knowledge in this book is not current.
Henriette's Herbal Home Page -
http://www.henriettes-herb.com... - there is a wealth of old, classical herbal texts that is digitalized here. Additionally, Henriette's knowledge and experience are informative.
