10 Acknowledgements I would like to acknowledge the help of each of my contributors who have provided their valuable contributions and time. I could not have completed the task of compiling this book without the inspiration and assistance of my Post-Doctoral Fellow, Dr Susan Murch. I would like thank my students and staff, Kristen Choffe, Mark Garnett, and Tannis Slimmon for their help with the numerous details. Finally, I would like to thank my family for their help, patience and understanding. I feel very fortunate to dedicate this effort to Sarla and Anand Saxena, my parents, who inspired me to have faith in God, always. xi

11 Preface The "plant" is often the most neglected part of plant-based medicine. Throughout time, humans have searched, collected, and effectively used plants for healing the ailments of body, spirit, and the mind. Today millions of people around the world consume plant-based medicines for a range of medical disorders and the global market for medicinal plants is in billions of dollars annually. Ironically, even in this age of scientific and technological advances, the mystery of what transforms a plant into a medicinal plant continues while consumers are embracing plant-based medicine to combat chronic diseases for which modem medicine has failed to provide an effective remedy or as preventative measures to stimulate body's own immune system. Not surprisingly, the medicinal plant based business is flourishing at a dramatic pace and at the expense of already declining population of plant species, many of which are at the verge of extinction. Despite their immense popularity, plant-based medicines face a serious scepticism. Their usefulness or even safety is questioned for lack of scientific evidence of medicinal efficacy. Our inability to understand how medicinal plants work should not be interpreted as ineffectiveness of the medicine. The history of medicinal plants spans many thousands of years. The evolutionary process of genetic and environmental adaptations over this time has altered and contributed to the spectrum of bioactive molecules in the species. This book is a collection of the thoughts of a select group of researchers who strongly believe in preservation of medicinal biodiversity and share the vision that research and development in this discipline will enhance and improve human health. Medicinal plants represent a unique opportunity for interdisciplinary xiii

12 xiv Conservation, Trade, Sustainability and Exploitation of Medicinal Plant Species research and a better understanding of their structure and function, and interactive synergy of bioactive molecules in response to their natural habitat will lead to the development of effective treatments for human ailments. It is my belief that the conservation and sustainable use of medicinal biodiversity coupled with efforts to enrich cultures where plant based medicine found its origin will make a remarkable difference in the lifestyles of people for whom growing medicinal plants is a way of life.
