Health and diseases along with therapeutics is a major concern of Ayurveda since antiquity. When the health sciences of the world were in primitive stage, Ayurveda was developed upto a great extent. Its fundamental principles attained a sound scientific background. Science is never static, it remains changing with the pace of time depending upon the available tools and technology of that time. Once upon a time Ayurveda was supposed to be a divine system of health, as history says. Gradually it became a science of common man with the need of time. The Trisutra of Ayurveda developed as Agnivesha Tantra and again got the caliber of Charaka Samhita as an advancement of the Ayurvedic knowledge. With the dew course of time, the extension of knowledge regarding this compendia was done and many chapters of Chikitsa Sthana along with Kalpa and Siddhi Sthana were added. Afterwards many commentaries came in to. existence on the basis of personal experiences of scholars of different era. Today in the era of the science and technology things have been changed up to great extent in science but not in Ayurveda. Although effort have been done from different corner of the globe. As this era is an era of data based or evidence based knowledge, keeping this view in mind, it was my long desire to collect and present this type of work of Ayurveda before the scientific community. So in this book an effort has been made to present the recent advances in Ayurveda. The chapters were invited from the scholars of Ayurveda from different discipline and reviewed by the experts of concern discipline respectively. In all the chapters, the applied aspects of the different concepts of Ayurveda from different disciplines have been done on scientific basis. It is the need of time that the new advances of Ayurveda should be placed at a common plateform. We have done possible efforts to enlist all new researches of Ayurveda, Shalya Tantra, Shalakya Tantra, Kayachikitisa, Balaroga, Prasuti Tantra, Ayurveda Siddhanta Swasthavritta, Rachana Sharira, Dravyaguna etc. in this book. We hope this book will be beneficial for the Ayurveda fraternity, specially for the younger generation. Suggestions and critics will be invited for further improvement. At the last but not least, we extend thanks and wholehearted gratefulness to all the contributors and reviewers of chapters in this book.

Health and healing is a major concern since antiquity. In Sushruta Samhita it is quoted that the creator recalled Ayurveda before the cre- ation of world due to its extensive need, as history reveals. Initially Ayurveda was a divine system of health and disease like other system of medicine in the world. Later on it became a science of common man as enumerated by our ancient sages, while describing the descend of Ayurveda in classics. India is a land of philosophy and our sages by their great vision tried to understand the relation between the nature and the living being which is a matter of curiosity to understand since long while. After a prolong investigation they came to a conclu- sion that whatsoever exists in the nature also exists in the living being especially the human being and postulated a law Yatha Brahmande Tatha Pinde. The scholars of Ayurveda applied that knowledge in the field of medicine and established another concept that is the Concept of Loka Purusha Samya (macrocosm-microcosm continuum). Ac- cording to this the entire concept of health and disease revolve around this very concept. With the pace of time there were many ups and downs in the history of Ayurveda, due to various reasons but it sustained itself somehow because it was a system, related to the life of common man which starts from inception of life or before that. It believes in the deeds of previous life because of having philosophical background. In present era it is facing challenges form inside and outside the country due to the advancement of science and technology. Although it a system of its own kind having its own fundamental principles, even then some efforts have been made to cope with the situation inside and outside country all over the world according to the demand of time. Change is natural phenomenon and unavoidable too, keeping this view the present work has been planned to present the views on recent advances made in different disciplines of Ayurveda. A lot of work has been done in different discipline but it is scattered, and not put at a common place. Few years back a project was done from Ayurveda University Jam Nagar in which the list of MD Thesis on different subjects were prepared.

Most of the chapters are in form of collection of subject matter amalgamated with science and technology. The matter has been arranged discipline wise alphabetically.
