The World's most powerful, visionary, easy to use and elegant programs for Homeopathy.
But don't take our word for it... Ask the world's most well-known homeopaths!

As a Hahnemannian practitioner, I have used MacRepertory and ReferenceWorks very effectively in practice and in teaching for over 20 years. ReferenceWorks includes many old journals that I frequently refer to in searching for cured cases and in preparing lectures. It is an exceptional tool.

These programs are far more powerful, more three dimensional, and yet easier to use, than anything else available. They are great teaching, and of course, studying tools. They make learning small remedies a piece of cake.

This version was very easy to install, and now I am exploring all of the new features for my next project, a volume on plant remedies. ReferenceWorks is incredible and, as far as I am concerned, you should rename it ReallyWonderful.

Over the past few years, I have been writing my new book about the “Table of Plants”. In order to compile it, I needed as many resources as possible about remedies. These included Materia Medica, old and new Provings and articles from professional journals and modern homeopathic books. I was able to find all of these and more in ReferenceWorks and, although I have additional homeopathic programs available to me, I found that ReferenceWorks is the richest, most advanced and easiest to use and to search. I deeply recommend it to everyone! In fact, I couldn’t have accomplished my book without it."
- Michal Yakir, RCHom
For nearly 25 years I have enjoyed using MacRepertory and ReferenceWorks tremendously. As I tell my students, these are simply the best, most beautiful, most visionary and easiest homeopathic software in the world and the ones you want to own.
