Benefitting from phytochemicals in medicinal plants has lately gained increasingly more global relevance. The medicinal bioactivity might range from wound healing activity to anti-inflammatory and anti-viral effects. This work describes the challenging scientific process of systematic identification and taxonomy through molecular profiling and nanoparticle production from plant extracts until a final use for e.g. cancer or HIV treatment.

Since ancient times, plants have been used as a prime natural source of alternative medicines and have played an important role in our lives. The old tradition of medicinal plant application has turned into a highly profitable business in the global market, resulting in the release of a large number of herbal products. People have tried to find different sources of medicines to alleviate pain and cure different illnesses. Due to severe constraints of synthetic drugs and the increasing contraindications of their usage, there is a growing interest world over in the usage of natural products based on medicinal herbs, hence, there is an ever expanding market of herbs and herbal based medicinal preparations all over the world. This has culminated into an exponential increase in number of research groups in different geographical locations and generation of volume of research data in the field in a short span of time. The path breaking advancement in research methods and interdisciplinary approaches is giving birth to newer perspectives. Therefore, it becomes imperative to keep pace with the advancement in research and development in the field of medicinal herbs. There are a large number of researchers in different parts of the world working on various aspects of medicinal plants and ‘herbal medicines’. The idea is to bring their recent research work into light in the form of a book. The proposed book contains chapters by the eminent researchers in different countries and working with different disciplines of medicinal plants. Articles pertain to different disciplines such as: 1. Resources and conservation of medicinal plants 2. Biosynthesis and metabolic engineering of medicinal plants 3. Tissue culture, propagation and bioreactor technology of medicinal plants 4. Phytochemical research on medicinal plants 5. Herbal medicines and plant-derived agents in cancer prevention and therapy 6. Herbal medicines and plant-derived agents in metabolic syndrome management 7. Herbal medicines and plant-derived agents in modulation of immune-related disorders 8. Herbal medicines and hepatotoxicity The book will prove itself an asset for the researchers, professionals and also students in the area of medicinal plants and mechanism of their action.

Medicinal and aromatic crops (MACs) are high-value crops since the natural products obtained from them are low-volume high-value commodities that have numerous applications in various sectors such as the food, beverage, food supplement, flavor and fragrance, perfumery and cosmetics, pharmaceutical and aromatherapy industries. In addition, the plant biomass is used in the production of teas and medical applications in traditional and also modern medicines. MACs are important mainly because they contain plant secondary metabolites such as essential oils, alkaloids, glygosides, saponins, tannins, vitamins and other bioactives. Plant secondary metabolites are differentiated from plant primary metabolites of photosynthesis and respiration since they are directly involved in growth and development of plants. Some MACs are used as spices and culinary herbs since they contain mainly essential oils, and are used as tonic to the digestive system, appetite modification and other systems and may facilitate nutrient uptake and utilization from various foods. A significant amount of MACs and their natural products have also demonstrated antimicrobial, antifungal and bactericidal activity and significant antioxidant capacity. In the past, MACs and their natural products have been used as a source for various medicines, in food and beverage production and in aroma products. Essentials of Medicinal and Aromatic Crops summarizes the current knowledge on medicinal and aromatic crops, including the agronomical practices of important MACs and their products, their beneficial effects and utilization of MAP and their products. The chapters provide a comprehensive guide to the most important and used medicinal and aromatic crops and their use in functional foods, nutraceuticals and as bioactives against various ailments, providing researchers, teachers, chemists, food scientists, agronomists and agroecologists in academia, industry and government a fully up to date singular source on this important topic.
