Medicinal plants are one of the numerous gifts of nature, they are loaded with several bioactive chemicals or phytochemicals as part of their normal metabolic activities. Medicinal plants as organic alternatives have increased due to the increasing awareness of food safety and the dangers of the indiscriminate use of antibiotics or synthetic chemicals. 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 growing year by year with the interest in natural medicines. There is a promising future of medicinal plants as there are about half a million plants around the world, and most of them are not investigated yet for their medical activities and their hidden potential of medical activities could be decisive in the treatment of present and future studies.
Today, the importance of research in the field of medicinal plants is felt more than ever.
