As there was a demand for discovering a device which can serve as an index to the ever enlarging Materia Medica, Dr Boenninghausen picked up the gauntlet. He published Therapeutic Pocket Book in 1846, wherein he incorporated information from his rich clinical experience and his earlier works ‘Repertory of Anti-psoric Medicines’, ‘Repertory of the Medicines which are not Anti-psoric and ‘Attempt at Showing the Relative Kinship of Homoeopathic Medicines’. This repertory is useful in cases which have complete symptoms, prominent sensation and modalities, prominent concomitants and cases where general symptoms are lacking. Relationship of remedies are available in the last chapter. It has 5 grade system to evaluate the symptoms. This book was written originally in German. This translation had been edited by Allen & is considered to be the most valuable edition. Allen rearranged this book and also added 220 remedies. * An invaluable bedside reference used by Master Hahnemann himself, frequently preferred over other works. * Systematic with detailed information on various locations, sensations, modalities and relationship of remedies * The work that paved the way for all the future repertories
