Synthesis 9.1 Tour

One of the greatest advantages of RADAR software is that it is built upon the Synthesis Repertory, considered the most reliable and accurate homeopathic database in the world.

The new version, Synthesis 9.1, represents 3 years of work by hundreds of homeopaths. It includes over 307,406 additions from hundreds of different sources, all meticulously compared with the original texts to ensure their accuracy.

It is this amalgamation of different homeopaths and sources of information, blended with the strict requirements of quality at every stage, that yields what is considered by most homeopaths as the ultimate repertory.

Boger-Bönninghausen Repertories Integrated

The major Repertory work of pioneer homeopaths Boger and Bönninghausen has been fully integrated into Synthesis. The new information has been documented in a very transparent way. The individualized, Kentian symptoms have been integrated seamlessly with the generalized, Bönninghausen symptoms, respecting both approaches.

Source Information Vastly Increased

Synthesis 9.1 now comes with 448,000 author notes or 21,820 pages of source information attached to it: The Source Repertory!

New Separate Repertories

A number of separate repertories, which can be used independently, accompany Synthesis 9.1. Most of this information has already been integrated into Synthesis as well.

Four New Concept Chapters

Concepts help you to more easily find symptoms in Synthesis. Four new concept chapters bring thousands of new concepts and a greater ability to find physical, mental, pediatric, and Latent Psora symptoms.

Remedies Copied to Analogous Superrubrics

Remedies of subrubrics were copied to the analogous superrubrics in the Mind chapter.

New "Personal Chapter"

The first chapter of Synthesis 9.0 is the new "Personal chapter". In this chapter you can add symptoms without using the structure of the repertory. As a consequence, it will not be possible to exchange these additions with others, nor to add symptoms of someone else's "Personal symptoms" chapter to your Synthesis.

Additions to this chapter are only useful as a temporary solution. The best way to add information to Synthesis remains the correct place within the existing chapters.

Released in Two Steps:

Synthesis 9 was released in two steps, Version 9.0 and Version 9.1 — each step adding new information to the repertory, with version 9.0 introducing the greatest amount.

The main innovations and new features of Synthesis 9.1 involve the streamlining and restructuring of the symptoms, whereas Synthesis 9.0 maintained the known, classical structure. Both versions of the repertory can be used simultaneously.

Timely Updated Information

Free downloads will be available to update Synthesis 9.1 with the most recent information as it becomes available.
