The Synthesis Repertory 9.1
- An Overview -

Ask any Homeopath to show you their key possessions and you will probably be invited to see their bookcase. For some Homeopaths of the electronic age, it may well be their homeopathic software.

Homeopaths realize that their library forms the foundation upon which their practice is built. They understand that to accurately analyze and arrive at the precise clinical conclusion, a variety of accurate resources must be at their fingertips.

Examine a little closer and you are bound to find one or two well-worn resources. More than likely, you will find a Synthesis Repertory in the midst of things.

Key Information

Jeremy Sherr's Foreword to Synthesis 9.1

Frederik Schroyens' Forward to Synthesis 9.1 presents an extensive description of the development of this new version.

Roger Morrison's Foreword to Synthesis 8 offers valuable information about the previous version of the repertory, a major step forward that allowed version 9.1 to rise to even greater heights.

Synthesis was never meant to be a static book, written for all generations to come, forever the words locked onto the pages. It was never designed to be "cast in stone", but to take on the role of a living, breathing document. Synthesis is a work in progress, continuously being updated, verified, and redefined.

Synthesis represents the fusion of the past with the present. It combines the tried and true historical findings of homeopathy with today's influx of new findings by the Homeopaths of today (and tomorrow). Synthesis is unique in that a key fundamental philosophy is to never sacrifice quality for quantity.
Synthesis Endorsement from Alfons Geukens, M.D.

Synthesis is the repertory of choice
in homeopathic schools around the world.

Synthesis is used in more than 70 countries and is available in English, German, French, Italian, Portuguese, Dutch, and Spanish.

Synthesis is available both in a book version and as electronic media (RADAR). Although Synthesis as a book is quite outstanding, the real power and heart of Synthesis rests in its ability to be tailored to the needs and discretion of the individual Homeopath. It is in the computerized version of Synthesis that this work meets this objective, and then exceeds it.
