Herbs are holistic agents as they work on many levels of the human being; and even on the physical level-on the level of biochemistry-their actions are complex and synergistic. Despite the complexity, pharmacologists have undertaken a lot of research to find out what the constituents are, and have classified these constituents according to their chemical groups. Even though this analytical approach to herbs is inherently limiting, it has produced a great deal of valuable information about some of the biochemical processes taking place. A knowledge of herb pharmacology is not essential to a herbalist, but is a great help in understanding the herb.
