Ever-changing environmental conditions and climatic transformations have affected each component of the environment. Increasing rates of soil, air and water pollution have altered the growth and production of vegetation to a greater extent and medicinal plants are also not spared from this. Medicinal plants form an important part of traditional and modern systems of medicine. The consumption of medicinal plants has increased over the last few decades. The present book provides detailed information on the topic with an emphasis on the effects of inorganic, organic (chemical), biological and other contaminants of medicinal plants. It provides a vast amount of information concerning the effects of various environmental factors on growth, productivity and secondary metabolite production in medicinal plants. The book also highlights the adverse effects of contaminants in plants and related toxicity of contaminated medicinal plants, with their possible effects on therapeutic efficiency and human health. The detailed information about the contamination and toxicity in medicinal plants will challenge the scientific community to find ways of countering many environmental adversities to protect, preserve and maintain many of the rare, highly valuable medicinal plants used in treating various diseases.

This book sheds new light on the role of various environmental factors in regulating the metabolic adaptation of medicinal and aromatic plants. Many of the chapters present cutting-edge findings on the contamination of medicinal plants through horizontal transfer, as well as nanomaterials and the biosynthesis of pharmacologically active compounds. In addition, the book highlights the impacts of environmental factors (e.g., high and low temperature, climate change, global warming, UV irradiation, intense sunlight and shade, ozone, carbon dioxide, drought, salinity, nutrient deficiency, agrochemicals, waste, heavy metals, nanomaterials, weeds, pests and pathogen infections) on medicinal and aromatic plants, emphasizing secondary metabolisms. In recent years, interest has grown in the use of bioactive compounds from natural sources. Medicinal and aromatic plants constitute an important part of the natural environment and agro-ecosystems, and contain a wealth of chemical compounds known as secondary metabolites and including alkaloids, glycosides, essential oils and other miscellaneous active substances. These metabolites help plants cope with environmental and/or external stimuli in a rapid, reversible and ecologically meaningful manner. Additionally, environmental factors play a crucial role in regulating the metabolic yield of these biologically active molecules. Understanding how medicinal plants respond to environmental perturbations and climate change could open new frontiers in plant production and in agriculture, where successive innovation is urgently needed due to the looming challenges in connection with global food security and climate change. Readers will discover a range of revealing perspectives and the latest research on this vital topic.

This report is structured in five parts: national framework for traditional and complementary medicine (T&CM); product regulation; practices and practitioners; the challenges faced by countries; and finally the country profiles. Apart from the section on practices and practitioners the report is consistent with the format of the report of the first global survey in order to provide a useful comparison. The section on practices and practitioners which covers providers education and health insurance is a new section incorporated to reflect the emerging trends in T&CM and to gather new information regarding these topics at a national level. All new information received has been incorporated into individual country profiles and data graphs. The report captures the three phases of progress made by Member States; that is before and after the first WHO Traditional Medicine Strategy (1999?2005) from the first global survey to the second global survey (2005?2012) and from the second survey to the most recent timeline (2012?2018).

Medicinal plants supply the ever-growing needs of humankind for natural chemicals, such as pharmaceuticals, nutraceuticals, agrochemicals, and chemical additives. These plants contain bioactive secondary metabolites, which possess antimalarial, anthelminthic, anti-inflammatory, analgesic, antimicrobial, antiarthritic, antioxidant, antidiabetic, antihypertensive, anticancer, antifungal, antispasmodic, cardioprotective, antithyroid, and antihistaminic properties. Secondary metabolites play a major role in the adaptation of plants to the changing environment and stress condition as they are affected by both biotic and abiotic stress. Humans rely on medicinal plants for various needs since ancient time, and their population still seems enough for fulfilling our demands. However, in the foreseeable future, we will be forced to think about the accessibility of resources for future generations. For these reasons, we must look for alternative sustainable options of resources which can protect these immensely important medicinal plants from various stresses induced by challenging environment. Evolving eco-friendly methodologies and mechanisms to improve these plants’ responses to unfavorable environmental circumstances is important in creating significant tools for better understanding of plant adaptations to various abiotic stresses and sustaining the supply of pharmaceuticals as global climate change intensifies. One of the great challenges in the near future will be the sustainable production of medicinal plants under increasing adverse effects of climate change. A combination of adverse demographic factors and climatological perturbations is expected to impact food and pharmaceutical production globally. Despite the induction of several tolerance mechanisms, medicinal plants often fail to survive under environmental extremes. To ensure their sustainable production under adverse conditions, multidisciplinary approaches are needed, and useful leads are likely to emerge. However, improving plants' performance under restrictive growth conditions requires a deep understanding of the molecular processes that underlie their extraordinary physiological plasticity. This edited volume emphasizes the recent updates about the current research on medicinal plants covering different aspects related to challenges and opportunities in the concerned field. This book is an attempt to bring together global researchers who have been engaged in the area of stress signaling, crosstalk, and mechanisms of medicinal plants. The book will provide a direction towards implementation of programs and practices that will enable sustainable production of medicinal plants resilient to challenging environmental conditions. Moreover, this book will instigate and commence readers to state-of-the-art developments and trends in this field.

How are pollutants transformed after their release into the environment? How are organisms exposed, and how do physiological alterations impact population dynamics and community structure? What direct or indirect impacts occur? As early as the 50s and 60s people living near industrial plants began to recognize undesirable changes in their environment - and to ask these very questions. The discipline of environmental toxicology addresses these questions. Written by an expert with over twenty years experience, Environmental Toxicology covers the physiological and toxicological effects of environmental toxicants on living systems. It explores the sources, and the physical and chemical characteristics of toxicants. It goes further to highlight their impact on plants, animals, and humans. The author furnishes information on the mechanism of action of individual chemicals and chemical combinations including cellular damage at the molecular level. He defines environmental toxicology and discusses the relationship between human activities and their impacts on living systems. He furnishes an overview of our changing environment and the possible link between that environment and the changing pattern of human diseases. Environmental Toxicology provides fundamental knowledge on the toxicological effects of environmental chemicals on living systems. Its fifteen chapters cover the occurrence of toxicants, air pollution, environmental metals, pesticides and related materials such as PCBs and dioxins, mutagenesis, and environmental cancer. This useful resource will enhance your knowledge of the impacts of environmental toxicants on living organisms.

The increase in global population, urbanization and industrialization is resulting in the conversion of cultivated land into wasteland. Providing food from these limited resources to an ever-increasing population is one of the biggest challenges that present agriculturalists and plant scientists are facing. Environmental stresses make this situation even graver. Plants on which mankind is directly or indirectly dependent exhibit various mechanisms for their survival. Adaptability of the plants to changing environment is a matter of concern for plant biologists trying to reach the goal of food security. Despite the induction of several tolerance mechanisms, sensitive plants often fail to withstand these environmental extremes. Using new technological approaches has become essential and imperative.
