"Introduction to Kasyapa-Samhita" is an attempt to study in depth the book Kasyapa-Samhita, the only source book of kaumarabhrtya. As presently available Kasyapa-Samhita is published on the basis of single incomplete manuscript, naturally various aspects of the book i.e. its authorship specially of supplementary section (khilasthana), its contributions in the advancement of the knowledge of ayurveda in general and kaumarabhrtya in particular, its period etc. need a fresh look. In present book an attempt has been made to discuss these various aspects on the basis of internal and external evidences, naturally it is likely to be very useful for historians, research workers, teachers and students of ayurveda.
