Cyrus Boger was perhaps the greatest scholar of Boenninghausen's work and this is the fruit of his labours.

This is a re-working and elaboration of Boenninghausen's famous repertory.

A good solid hardback from B Jain of New Delhi
Very popular among the more classically inclined homeopaths
The first version of Boenninghausen’s reportorial work was published in German in 1833 and in time was worked upon to create his Therapeutic Pocket Book in 1846 which still sells to this day. It was used by many of the leading lights of nineteenth century homeopathy such as Stuart Close and Timothy Field Allen.
 
In the early twentieth century, Cyrus Boger decided to work upon this groundbreaking tome and in turn produced the Boger-Boenninghausen Characteristics and Repertory in 1905. He refined his own work and the second edition came out in the mid nineteen thirties. .
 
How is this work different to Kent’s? It is geared to a way of analysing the case mostly upon general symptoms rather than particulars. It tends not to focus upon the strange, rare or peculiar but instead seeks to concentrate upon modalities and the concomitants.
There is greater weight given to the pathological and objective symptoms rather than the mentals. Symptoms are looked at regarding four components, namely their location, their modalities, their sensations and their concomitants.
This a recent edition that is compact, weighing half a kilo less than some previous printings, and has had some extra checking by Dr D.P. Rastogi and Dr V.D.Sharma. Apparently they have made 100 corrections to the abbreviations of the remedies in the repertory which may not have always been consistent. These are shrinkwrapped and were recently published by B Jain.
