Kushtasazi today is considered as an essential element of liberal education at all levels. A well educated person is expected to be familiar with various areas of calcination. So, it is not surprising that it has emerged as a major section in the field of Unani pharmacy (Ilmul Saidla). Kushta (calcined product) is the dosage form concerned with rejuvenation, longitivity, virility, vitality. Works on kushtajat are now read by a much wider audience and now is no longer confined to historicians. The need of serious treatment is this subject is now felt more widely. So far no attempt has been made to study this type of dosage form in a scientific manner. This is because of a lack of communication among traditional healers, physicians and scientists and the unavailability of the literature in English. So, the present book has been designed keeping in view the fact that students require greater depth and breadth of knowledge to tackle complex nature of calcination technology and with the self effacing aim in the direction of development and understanding of kushtasazi. All efforts have been made to make this book as informative as possible.
