The answer is not as straightforward as you might think. The best Repertory is not really a repertory at all. Hahnemann worked on a repertory in the latter years of his life, and despite his genius, his mind was not suited to collating the symptoms in a manner that made it easy to retrieve information for prescribing. He encouraged Boenninghausen to make a repertory, and so the SRA and SRN came into being, Filling page after page of key symptoms from remedies, the size of the books became obviously unwieldy for easy use, and so that work was placed on one side while Boenninghausen worked on a new concept. It was a memory aid for physicians at the bedside.
Using 125 medicines of which he had a deep knowledge of, Boenninghausen broke apart the symptoms culled from the SRA and SRN and componentized them. Example: sharp pain in left temple on awakening. This would be split to: Temples left. Pain sharp. waking agg.
Using this method, Boenninghausen reasoned that a remedy would be able to found using the characteristics of the provings even if a particular symptom had not been found in the remedy. After extensive trialing, it was found to be extremely accurate and Hahnemann approved of its use as it followed precisely the methodology Hahnemann used in his own rationale.
The Therapeutic Pocket Book became one of the most respected and valuable books used to elicit a remedy for patients.Sadly with the advent of Kents repertory, it fell by the wayside. Boger tried to enlarge it but did not follow the model or criteria and it became inaccurate. Kents repertory, if you follow the historical detailing has proved to be not as accurate or useful as would be hoped for, and yet the homoeopaths of today have added to it greatly, thus compounding the unfixed errors.
George Dimitriadis released in 2000 a revised and altered clinical version of the Therapeutic Pocket book. His book was based on extensive research from original sources. In 2010 Polony and Weaver released a computer version of their own research of the TPB and maintained the original layout of Boenninghausen. It is released in English German and Spanish.
The book version of George Dimitriadis TBR is $320. The TBR computer version is $A880 from http://hahnemanninstitute.com
Polony and Weaver, The P & W 2012 version of the Therapeutic pocket Book is available for $US799 from, http://homeopathyonline.org (German English and Spanish full translations including the individual language interface.).
Is the work accurate in the modern world? Vladimir Polony, Gary Weaver and George Dimitriadis use their own versions of the book almost exclusively in their practice. The confidence in prescribing and the results speak for itself. Because both versions have the same sources (1846 handwritten and print edition), although laid out a little differently and the rubrics worded slightly differently, the actual remedy suggestions are the same if the symptoms are chosen accurately. The principle of the methodology can be reproduced time after time for the benefit of the patient. Research into the writings of Hahnemann, the Materia Medica’s and dictionaries of the day and the personal correspondence between Hahnemann and colleagues, shows a deep, precise and accurate comprehension of what the individual medicines can produce in terms of symptoms, and as such are represented completely by the method of Boenninghausens Therapeutic Pocket book.
No other repertory has Hahnemanns seal of approval.
