Garlic and Other Alliums: The Lore and The Science Author: Eric Block


About this book

The name "Allium" is said to come from the Greek word to avoid because of its offensive smell. The genus Allium includes more than 800 species of which only a few have been cultivated as foods. Many of the other members of this genus are popular with gardeners as easy to maintain perennials, although the smell of some members of the genus can be off-putting. The smell is a consequence of breakdown of sulfur-containing compounds which is a characteristic of this family of plants. Garlic, onions, leeks, chives and other members of the genus Allium occupy a unique position both as edible plants and herbal medicines, appreciated since the dawn of civilization. Alliums have been featured through the ages in literature, where they are both praised and reviled, as well as in architecture and the decorative arts. Garlic pills are top-selling herbal supplements while garlic-based products show considerable promise as environmentally friendly pesticides. The remarkable properties of the alliums can be understood based on the occurrence of a number of relatively simple sulfur-containing chemical compounds ingeniously packaged by nature in these plants. This unique book, with a foreword by 1990 Nobel Laureate E.J. Corey, outlines the extensive history and the fascinating past and present uses of these plants, sorting out fact from fiction based upon detailed scrutiny of historic documents as well as numerous laboratories studies. Readers will be entertained and educated as they learn about early cultivation of garlic and other alliums while being introduced to the chemistry and biochemistry. They will learn how alliums have been portrayed and used in literature, poetry, the arts and how alliums are featured in the world's oldest cookbook. Technical material is presented in a manner understandable to a general audience, particularly through the use of illustrations to simplify more difficult concepts and explain how experimental work is conducted. The book is heavily illustrated with examples of alliums in art, literature, agriculture, medicine and other areas and includes rare botanical drawings of many members of the genus Allium. Essential reading for anyone with a general interest in science, the book is written at a level accessible to experts and non-experts alike. It has sufficient additional detail and references to satisfy both those wanting to know more, as well as researchers in disciplines as diverse as archaeology, medicine, ecology, pharmacology, food and plant sciences, agriculture, and organic chemistry.

Author information

Eric Block, Carla Rizzo Delray Distinguished Professor of Chemistry at the University at Albany, State University of New York, received a B.S. in chemistry from Queens College of the City University of New York and an M.S. and Ph.D. in chemistry from Harvard University with 1990 Nobel Laureate E.J. Corey. Prior to coming to Albany he was Professor of Chemistry at the University of Missouri-St. Louis and he has been a Visiting Professor at Harvard University, the Universities of Illinois-Urbana, Frankfurt, and Bologna, the Weizmann Institute of Science and Visiting Fellow at Wolfson College, Cambridge University. Recipient of a John Simon Guggenheim Fellowship (1984), the ACS Award for Advancement of Application of Agricultural and Food Chemistry (1987), the International Council on Main Group Chemistry Award for Excellence in Main Group Chemistry Research (1994) and the Kenneth C. Spencer Award of the Kansas City Section of the ACS (2003), Block is the author of more than 220 papers, 5 patents, 4 books, and is a member of the editorial advisory board of the Journal of Agricultural and Food Chemistry. He is known for his discoveries elucidating the natural products chemistry of Allium species (garlic, onion, etc.) accomplished over a period of 35 years including: determination of the structure of the lachrymatory factor of the onion and its dimer; identification and synthesis of "ajoene" and vinyldithiins, anticoagulants from garlic, and bis-sulfine, cepaenes, and zwiebelanes, biologically active onion flavorants; identification of organoselenium compounds in Allium volatiles and in human garlic breath; identification of trace level Allium selenoamino acids; development of analytical methods for identification of Allium organosulfur flavor components. He co-authored a clinical trial of the effectiveness of garlic and garlic supplements as lipid-lowering agents and is researching applications of garlic-derived compounds as environmentally benign pesticides.
