Pharmacognosy, the science of nature-derived drugs, pharmaceuticals, and poisons, played a crucial role in the development of modern medicine, and now has an equally important place in healthcare all over the world. This wide scope ranges from traditional medicine systems and herbal and nutritional therapies, the preparation and use of highly standardised and clinically tested herbal medicines, to the production of potent drugs used only in a purified form. Natural sources mainly focus on plants, fungi and algae, but drug discovery of novel compounds and structures includes bacteria and even marine animals. Fundamentals of Pharmacognosy and Phytotherapy is a landmark textbook that covers this spectrum of medicinal plant use. Written by leading experts in this field, this book takes the reader through the history, identification, and quality assurance of plant-based medicines to their therapeutic properties, safety, and compatibility and interaction with prescribed drugs. Aimed at students of all healthcare professions, including pharmacy, medicine, nursing and complementary therapies, the comprehensively updated information in this textbook is also relevant to those companies and organisations concerned with the regulation and testing of herbal medicines (phytomedicines), other natural health products, nutraceuticals and dietary supplements.
