The “Echter Speik” (Valeriana celtica subsp. norica) is more than a modest alpine herb found in the Nockberge Mountains of Carinthia. This book is a tribute to its rich history as a medicinal plant, trade good and cultural symbol—while exploring the pressing questions of conservation and sustainable use in today’s world. In a truly inter- and transdisciplinary research project, authors from science, regional practice and administration have created a vivid portrait of the plant and its significance. With contributions from botany, pharmacy, regional planning, environmental law, ethnology and economics, the book offers an in-depth, multifaceted perspective on this remarkable species within the UNESCO Biosphere Reserve Nockberge. From ancient trade routes to modern soap production, from biodiversity law to local development strategies—the book links academic insight with practical relevance. It is aimed at professionals and researchers as well as readers with a passion for nature, culture and sustainability. A compelling read for anyone who wishes not only to protect nature, but to understand and shape it for future generations.
