    For Lois Stopple,


    What can I say, after 600 odd pages (odd pages indeed), I'm tongue tied! You have healed me heart and soul, with


    the celebration of life and joy that you are. This book may have been written by me, but it was midwifed by you.


    Sweet blossom come on under the willow


    We can have high times if you'll abide


    We can discover the wonders of nature

    ACKNOWLEDGMENTS


    My deepest appreciation to Cheri Quincy, DO, for the continuing encouragement and support. Thank you for


    your confidence in me, even when I couldn't even spell the word!


    It is with love and gratitude that I acknowledge my friends and colleagues in the North American commu-


    nity of herbalists for making this escapee from Thatchers' Britain so welcome. The ideas in this book have been


    gestating over the years in discussions with many, many herbalists. The U.S. herb world is blessed with an at-


    mosphere of openness and mutual support that is unique and deeply nurturing. We can thank Rosemary Gladstar


    for so very much . . .


    There is so much I could say to each of you, so I'm copping out and simply "naming names." No special order,


    I love you all: Cascade Anderson-Geller, Paul Bergner, Jane Bothwell, Mark Blumenthal, Don Brown, Ryan


    Drum, Rosemary Gladstar, Mindy Green, Christopher Hobbs, Tori Hudson, Feather Jones, Gail Julian, Kathi


    Keville, Tierona Low Dog, David LaLucerne, Rob McCaleb (and everyone at the Herb Research Foundation),

    Ulhrich, Roy Upton, Marty Wall, David Winston, Linda Wolf, Tom Wolf, Matthew Wood, Dusty Yeo.


    This book is much better than it deserves to be because of the superlative guidance of herbalist/editor ex-


    troadinaire Evelyn Leigh. Thank you for being so knowledgeable, insightful, literate, and understanding of this


    aging deadhead. You made the process pleasant, rewarding (or is that rewording?), and even entertaining.


    To Jeanie Levitan, the first editor to give me her toothbrush! All authors should hope to be blessed with


    guidance from someone with your erudition and warmth. To Jamaica Burns for editorial help above and beyond


    the call of duty. Sorry about the obscure Chinese citations.


    I want to thank the many groups of students I have had the honor of working with over the years. You all


    know who you are. In case you've forgotten, you went to one (or more!) of the following institutions: the


    California School of Herbal Studies, the Rocky Mountain Center of Botanical Studies, Bastyr University,


    National College of Naturopathic Medicine, California Institute of Integral Studies, and the National College


    of Phytotherapy.


    Sonoma County reference librarians have been a great help during the writing of this book. What would we


    do without libraries?


    To Sasha Shulgin, Grant Morrison, Hakim Bey, Jerry Garcia, and Ozric Tentacles for the help with sanity


    maintenance (and furtherance . . .). CONTENTS
