Preface This publication is the outcome of a project funded by National Medicinal Plants Board, New Delhi, on Developing pharmacognostic standards of important bark drugs used in Ayurveda. The project involves standardisation of 60 bark drugs/their substitutes/market adulterants. Twenty drugs out of sixty are covered in this first volume.

The past decade witnessed a worldwide acceptance of the traditional systems of medicine and also the scientific exploitation of medicinal plants. Considering the tremendous increase of worldwide interest in medicinal plants and their products in the recent past, the World Health Organization (WHO) has recognized the importance of Traditional Systems of Medicine (TSM) and the Folk-lore remedies, which mainly depend on plants for the treatment, cure, prophylaxis and modulation of immune response. India has a long history and most diverse cultural traditions associated with the use of herbal medicines and has developed a distinct system for using the bark. Ayurveda, Siddha and Unani are the three important traditional systems in practice in India which are being called Indigenous Systems of Medicine. Among them, Ayurveda is the oldest and widely popular practising system. The main raw materials used for these systems are plants and their derived products. The plant parts including roots, stems, barks, heartwoods, leaves, flowers, fruits, seeds and exudates constitute the major portion of the raw drugs used in these systems of medicine. The importance of standardisation of Ayurvedic medicines using modern methods, has attracted some attention only in recent times. But without establishing the proper standards for raw materials, it would be very difficult to evolve standards for the formulations.
