Medicinal plants are an integral part of our health care system. Medicinal plants play a golden role not only as traditional medicine but also as trade commodities, meeting the demand of distant markets for the development of new drugs. There is a growing interest all over the world in the usage of natural products based on medicinal herbs due to the severe constraints of synthetic drugs and the increasing contraindications of their usage. Ensuring the safety, quality and effectiveness of medicinal plants and herbal drugs very recently became a key issue in industrialized and developing countries, hence, the global market of herbs and herbal-based medicines is glowing year by year with the interest in natural medicines. Herbal drugs can help the emergence of a new era of the healthcare system worldwide, not only to treat diseases but also to prevent them and maintain health.
Now the importance of research in the field of medicinal plants is felt more than ever.

The idea is to highlight their recent research work in the form of a book. The presented book includes chapters written by eminent researchers from different geographical areas and working with different disciplines of medicinal plants. The presented book not only expresses recent trends of medicinal plants research but also opens the door for future research in the field of medicinal plants by aggregating our present knowledge. The book will prove to be an asset to researchers, professionals and students in the field of medicinal plants and their mechanisms of action.
