The book has been compiled to bring together comprehensive information and literature on medicinally and commercially important plants in respect of biosystematics, reproductive biology, genetic amelioration, cultivation, conservation, chemistry, pharmacology, trade, value addition and future prospects for wider readership. The ten plants are: Aegle marmelos, Aloe vera, Saussurea costus, Aconitum heterophyllum, Asparagus racemosus, Berberis aristata, Bergenia ciliata, Crocus sativus, Picrorhiza kurroa and Piper longum. The primary motivation for writing this book was to collate scientific information on some of the most privileged plants used in India and to give a critical analysis of next-generation research problems worth pursuing. We have identified a set of ten plants which have great potential for safeguarding and promoting wellness and human health and possess promising potential of product development for commerce. Recent global regulatory developments, exemplified by US-FDA creating a road-map for marketing approval of plant- based botanical drugs and nutritional supplements, has opened up global market for Indian medicinal plants. Over a hundred Indian plants that have been used in traditional systems of medicine for centuries have now been recognized and included in the global pharmacopoeias (US, EU and Japan). In 2015, the Drugs Controller General of India (DCGI) has created a separate category for phytopharmaceutical drugs, and over 100 plants have been approved by Food Safety and Standard Authority of India (FSSAI) for inclusion as nutritional products.
