This book is a step ahead of the "Encyclopedia of Homoeopathy" by T F Allen. Here the author attempts to correct and supply the omissions which were there in the Encyclopedia. This massive Materia Medica which is based on Hahnemann's schema of proving is a complete record of all proving. New cases of poisoning are an exclusive feature. In this book, a large amount of information is condensed and adjusted to very small space. Comparisons of each drug have been made with few of its allies. The concise clinical information given with the remedies is an added advantage which would be of interest to those who are keen on research and further studies. A practical working information on 'Selection of Remedy' is a beneficial section. This book will contribute to the application of homeopathic therapeutics in a much wider sense.
