J.S. Qadrys Textbook on Pharmacognosy has been widely acclaimed as an extremely useful book for the undergraduate students of pharmacy ever since it saw the light of the day some forty years ago. The remarkable thing about the book is that each one of its sections dealing, obviously, with the study of biological, phytochemical, analytical (characterization, evaluation and standardization of natural products) as well as pharmacological and other related information is supported with textual and illustrative presentation. The book, thus deals with all the necessary components of this multi-disciplinary subject in a manner that enables the reader to go over to the systematic study of each individual drug with clarity and confidence. The present edition, the 16th, has been extensively revised and enlarged. New topics, new illustrations and new coloured plates have been added to the text. Topics on traditional systems of medicine and complementary and alternative medicine as well as the drugs used in those systems considered relevant to the subject have also been added in the new chapters which have unquestionable enhanced the value and worth of the book.
