SPE is a synthesis of certain aspects of aromatherapy, doctrine of signatures, classical homeopathy, modern physiology, Kabbalah, philosophy, anthroposophical science, Chinese medicine, herbal medicine and folklore, depth psychology, gemstone healing and color therapy. Accordingly, each chapter in Berkowsky's Synthesis Materia Medica/Spiritualis Of Essential Oils  uses elements from this synthesis in concert to elaborate a clear picture of the inner soul nature not only of the essential oil in focus but also of the individual for whom that oil would be a soul-level specific.

In each chapter, Dr. Berkowsky provides sufficient contextual explanatory information to allow even those who have had no prior experience with some of the elements he uses in his synthesis (e.g., Chinese medicine or Kabbalah) to be able to understand and practically apply the information presented in the chapter.

For those interested in deep, soul-level work with essential oils, these information-rich chapters and recordings are deeply insightful, moving and invaluable.

Dr. Berkowsky has been teaching for more than 35 years and the many thousands who have attended his classes or lectures or who have listened to him discuss various topics on radio programs consider him to be one of the finest and most knowledgable teacher/practitioners they have ever encountered.
