This book is based on 30 years of experience as a clinician and teacher. The subject is the most important part for a successful practice. "The Materia Medica" is a vast ocean and the symptoms under each remedy innumerable. As said by Dr Kent, 'All who would memorise the Materia Medica must ignominiously fall'. In this book author has tried to cope up with the shortcomings in grasping the "Materia Medica". The salient features of this edition are: constitutional, specific, biochemic and pathological indications; dosage, repetition and duration of action; relationship of remedies; comparison with other remedies; causes and disease complaints and characteristics; and, generals and modalities.
