Medical Herbalism contains comprehensive information concerning the identification and use of medicinal plants by chemical structure and physiological effect, the art and science of making herbal medicine, the limitations and potential of viewing herbs chemically, and the challenge to current research paradigms posed by complex plant medicines. It also includes information on toxicology and contraindications, the issues involved in determining dosage and formulation types for an individual, guides to the different measurement systems and conversion tables, and the pros and cons of both industrial and traditional techniques. With additional sections devoted to the principles of green medicine, the history of Western Herbalism, the variety of other medical modalities using medicinal plants, an extensive resource directory, and a discussion of treatments organized by body system, Medical Herbalism is the comprehensive textbook all students and practitioners of clinical herbalism need to develop their healing practices.

In this herbal guide to healthy aging, medical herbalist David Hoffmann discusses how to maintain the body’s vitality as we age and how to treat and prevent the health concerns brought about by aging. He provides herbal treatments to restore and protect each of the body’s major systems--from the muscles, bones, and digestive system to the pulmonary, cardiovascular, and reproductive organs--as well as herbal remedies for specific ailments such as prostate enlargement, hot flashes, hypertension, insomnia, bronchitis, varicose veins, and arthritis. He shows how herbs can help minimize dependence on conventional medical treatments and provide a safe and welcome alternative to the unpleasant and sometimes dangerous side effects of synthetic drugs. In the materia medica, Hoffmann details more than 150 health-promoting herbs and their actions on the body and mind, preparation methods, and recommended dosages. This authoritative guide to herbal preventive medicine offers holistic treatments designed not only to promote vibrant health but also to provide a way to age with grace.

A guide to the cultural reawakening of modern herbalism Providing a comprehensive guide to the dynamic new landscape of modern herbalism, renowned medical herbalist David Hoffmann explores how ancient healing modalities are once again becoming prominent—just when the planet most needs them. Acknowledging the ecologically unsustainable course we are on as a species, Hoffmann reveals herbalism as a way to reconnect with the land and ourselves, a powerful way to participate in the earth-centered green transformation underway in our culture. Using the concept of viriditas—the understanding of nature as divinely ­intelligent—Hoffmann explores modern herbalism in detail. He looks at the deep involvement of herbs and their constituents in ecology, revealing the universal role of plants in integration and homeostasis. He examines the concepts of biodiversity and chemodiversity, elaborating on the ecological role of human-herb interactions and co-evolutionary relationships between species. Presenting evidence of medicinal plant use by animals and early humans, he reviews herbalism from its ancient roots to the modern varieties in practice today, emphasizing how herbalism that developed outside of the dominant culture laid the foundations for the effective, simple techniques relevant for our modern world. He examines the radical and non-hierarchical roots of herbalism, considering the parallels between the field’s development and the growth of spiritual awakening and social radicalism. Exploring herbalism through the modern scientific lens, Hoffmann reveals the exponential growth in recent research and peer-reviewed literature on phytotherapy and herbs. He describes the problems inherent in herbalism’s integration into the global marketplace, emphasizing that herbalism must stay rooted in the health of the people to avoid becoming commodified. He also offers a range of herbal approaches to support personal and cultural resilience during the crises humanity is facing. Ultimately, Hoffmann says, a vibrant culture of herbalism can have critical implications for the future: in the face of ecosystem breakdown and myriad crises, earth-centered herbalism can serve as a crucial force for health and resilience.

David Hoffmann stellt die Synthese der ersten Niobtetrelylidinkomplexe des Germaniums und Zinns durch effiziente Salzmetathesereaktion vor. Beide Verbindungen wurden vom Autor IR- und Multikern-NMR-spektroskopisch charakterisiert und ihre Molekülstruktur im Festkörper durch Röntgenstrahlenbeugung am Einkristall aufgeklärt und diskutiert. Beide Strukturen weisen einen sehr kurzen Tetrel-Niob-Bindungsabstand und ein fast linear koordiniertes Tetrelatom auf. Die Reaktivität des Niobgermylidinkomplexes gegenüber kleinen polaren Molekülen wurde anhand der Reaktionen mit Methanol und Wasser geprüft und die Redoxeigenschaften mittels cyclovoltammetrischer Messungen untersucht.
