Still considered the definitive work on medicinal herbs and their uses after two decades, the Handbook of Medicinal Herbs has undergone a long-anticipated revision. In the second edition, world-renowned ethnobotanist James A. Duke provides up-to-date data on over 800 of the world's most important medicinal plant species. The book contains more species, phytochemicals, proven indications, folk indications, and dosage data than the first edition in a new easier to use format. The in-depth content, the addition of color plates and over 200 black and white illustrations makes this book the most comprehensive resource on medicinal herbs available.NEW IN THE SECOND EDITION:"Over 100 color plates, 4 color maps"Over 200 black and white illustrations"Over 800 medicinal plants - more than twice as many as the previous edition organized alphabetically by common name"More herbs from the African, Ayurvedic, Chinese, and Jamu traditionsEASY ACCESS TO INFORMATION YOU NEEDDesigned to give you fast access to the information you need on a regular basis, this new edition is organized more systematically than any other medicinal herb publication. The entries are now arranged alphabetically by common name with the scientific name in parenthesis. Major synonyms are also provided."It has become increasingly clear that there are hundreds of biologically active compounds, often additive or synergistic, in all our plants, foods, spices, herbs, medicinal, and poisonous plants. The debate continues on how these plants work and how they should be used.

Fluid dynamics is fundamental to our understanding of the atmosphere and oceans. Although many of the same principles of fluid dynamics apply to both the atmosphere and oceans, textbooks tend to concentrate on the atmosphere, the ocean, or the theory of geophysical fluid dynamics (GFD). This textbook provides a comprehensive unified treatment of atmospheric and oceanic fluid dynamics. The book introduces the fundamentals of geophysical fluid dynamics, including rotation and stratification, vorticity and potential vorticity, and scaling and approximations. It discusses baroclinic and barotropic instabilities, wave-mean flow interactions and turbulence, and the general circulation of the atmosphere and ocean. Student problems and exercises are included at the end of each chapter. Atmospheric and Oceanic Fluid Dynamics: Fundamentals and Large-Scale Circulation will be an invaluable graduate textbook on advanced courses in GFD, meteorology, atmospheric science and oceanography, and an excellent review volume for researchers.
