Shilajit in Perspective Shibnath Ghosal Publisher: Narosa, New Delhi, and Alpha Science International, Oxford, UK, 2006 ISBN 81-7319-732-6, pp 250, price US$98. Shilajit is an unusual and intriguing medicinal substance, a paleo-humus formed from fossilized marine invertebrates, resins and plant material, but the composition can vary widely and its exact origin is still the subject of debate. It has long been an important therapy in the Ayurvedic system of medicine, but is now also attracting much wider interest elsewhere. âShilajit in Perspectiveâ is therefore a timely publication which will help to provide evidence to support its use. The introductory chapters discuss the varieties, their nature and theories of origin of various forms of Shilajit in depth. The chemistry is very well documented and numerous chemical structures, chromatograms and spectra are included in the book to produce a comprehensive overview of its composition, analysis and characterization. As well as a wide variety of common natural products, Shilajit has been found to contain some unique and interesting compounds, such as a number of dibenzo-alpha pyrone complexes with chromoproteins, and these are discussed in detail. Traditionally, Shilajit is used as a Rasayana, or general tonic in Ayurveda, and it is also considered to increase virility and cure diabetes. It has immune enhancing effects and many other important biological activities and these are all explained at length. The book is an informative, detailed and carefully researched account of the modern scientiï¬c work which demonstrates the large number of useful properties shown by Shilajit. It is a clearly laid out, well illustrated with useful diagrams and photographs and comprehensively referenced. The author, Professor Ghosal, is the foremost expert on the subject, and this volume contains a wealth of reliable information about this fascinating medicinal substance. Elizabeth M.
