In the 20 years that have passed since the publication of the first edition, both Poison Control Centers and Emergency Departments have witnessed an expansion in the number and variety of poisonings caused by toxic plants. At the same time, there is a proliferation in the diversity of plants in our gardens and homes, continually expanding the range of possible consequences from exposure to toxic plants.

This second edition of the Handbook of Poisonous and Injurious Plants is created to assist the clinician in the initial response to the needs of a child or adult exposed to a poisonous or injurious plant. It lists common plants that might lead to the development of the symptom complex and describes the mechanisms of action of the implicated toxin, additional clinical manifestations, and specific therapeutics for each presentation. It has methodically enhanced the previous edition's botanical rigor with insights from both pharmacognosy and clinical medicine to make it a truly comprehensive source.

With its thorough references and full-color photos of hundreds of potentially toxic and injurious plants inside the home, anyone who has an interest in plants will find this book useful outside in the garden or out in the wild.

This book will fascinate botanists, horticulturists, and naturalists as well as hikers, gardeners, and all those who simply enjoy the wonders of nature and the great outdoors!

With Foreword by Lewis R. Goldfrank, MD and Introduction by Andrew Weil, MD
