The use of aromatic plants has been practised since ancient times as is evidenced by records of Chinese, Egyptian, Mesopotamian, Greek and Roman origin; recent findings in Pakistan prove that it goes as far back as 5000 years. Accordingly, the importance and value ascribed to them were always high. Either as a medicine, a foodstuff, a seasoning, a cosmetic or an element of religious rituals the aromatic plant was indispensable. It is not to be forgotten that desire tor the riches of India - spices among which - and the struggle to monopolize the trade of the latter con tributed to the opening of new sea routes, discovering of continents and altering the picture of the known world. With the advent of modern civilization, characterized by scientific and technological development which dIverted estimation and consumption towards artificial products, aromatic plants experienced a temporary de cline of use retaining, however, theIr importance In sectors such as the culinary art and cosmetics industry.

There are many good books in the market dealing with the subject of allelopathy. When we designed the outline of this new book, we thought that it should include as many different points of view as possible, although in an integrated general scheme. Allelopathy can be viewed from different of perspectives, ranging from the molecular to the ecosystem level, and including molecular biology, plant biochemistry, plant physiology, plant ecophysiology and ecology, with information coming also from the organic chemistry, soil sciences, microbiology and many other scientific disciplines. This book was designed to include a complete perspective of allelopathic process. The book is divided into seven ...
Science is essentially a descriptive and experimental device. It observes nature, constructs hypotheses, plans experiments and proposes theories. The theory is never contemplated as the 'final truth', but remains ever subject to modifications, changes and rejections. The science of allelopathy in a similar way has emerged, and exists on a similar footing; our endeavour should be to keep it fresh and innovative with addition of newer in formation and concepts with the rejection of older ideas and antiquated techniques. During the past few decades encouraging results have been obtained in various aspects of allelopathic researches. However, in addition to continuing efforts in all these direct...
The genus Thymus consists of about 350 species of perennial, aromatic herbs and subshrubs native to Europe and North Africa. Various types of thyme are used all over the globe as condiments, ornamentals and sources of essential oil. Thyme oil (distilled from its leaves) is among the world's top ten essential oils, displaying antibacterial, antimyco
This timely and comprehensive update of the original text integrates a diverse and scattered literature to produce a synthetic account of Mediterranean plant evolutionary ecology. It maintains the accessible style of its previous version whilst incorporating recent work in the context of a new structural framework.
Plant embryology, dealing with the regularities of initiation and the first stages of development of an organism, is now flourishing because of the overall progress being made in natural sciences. Such discoveries of the 20th century as production of plants from a single somatic cell, experimental haploidy, and parasexual hybridization were of general biological significance. The combined efforts of embryologists, geneticists and molecular biologists yielded the discovery of specific genes that control meiosis, egg cell development and early stages of embryogenesis. The tendency to synthesize data of embryology and genetics has become increasingly noticeable. It is connected with the fact th...
Allergy is an immunological disease caused by multiple factors and characterized by variability, specificity and complexity. "Multidisciplinary Approaches to Allergies" covers diverse aspects ranging from basic molecular mechanisms to societal issues within the framework of multidisciplinary approaches to allergies. It contains 29 chapters in 6 parts: General Allergy; Allergenic Sources and Allergens; Diagnosis; Therapies and Pharmacy; Hypoallergenic Products; Environment, Hygiene and Societal Issues. It can be used in education and research as introductory and supplementary material. It is also an indispensable tool for scientists and doctors who are searching for an integrated way for alle...
The third edition of the unparalleled reference on natural ingredients and their commercial use This new Third Edition of Leung's Encyclopedia of Common Natural Ingredients: Used in Food, Drugs, and Cosmetics arrives in the wake of the huge wave of interest in dietary supplements and herbal medicine resulting from both trends in health and the Dietary Supplement and Health Education Act of 1994 (DSHEA). This fully updated and revised text includes the most recent research findings on a wide variety of ingredients, giving readers a single source for understanding and working with natural ingredients. The Encyclopedia continues the successful format for entries listed in earlier editions (cons...
As in previous volumes, readers will find a multidisciplinary forum for communicating knowledge related to the botany, horticulture, and pharmacology of herbs, spices, and medicinal plants. While magical and mystical powers have been associated with these plants through the ages, continued investigations in such areas as production, nomenclature, uses, chemical constitution, and dynamics help elucidate the affiliated chemical and physical processes that contribute to their unique flavor, fragrance, pharmacological, and other bioactive properties. This collection of articles examines the potential of natural products as pesticides, the richness of the Chinese Pharmacopeia, the similarities of Eastern Asian and Eastern North American medicinal plants, the use of borage as a source of gamma linolenic acid, and the botanical nomenclature of medicinal plants.
