Details a wide variety of herbs with their common uses, dangers, and benefits. The most useful parts of each herb are described, as well as methods of extraction and application. While not really a Complete reference for the truly advanced practitioner(such a work would be indeed be massive,) it is useful for the novice, adept, or even the herbalist who studies from a very clinical standpoint(there's a good deal of information here on the active chemicals and types found in herbs.) Some of the more scientific information may leave the average reader a little confused, but the basic herbal knowledge in this work is well worth its cover price.
