Paperback 349 pages / Form and Function by Julian Barnard begins the process of explaining why and how the essences are so effective. It describes how Dr Bach made his discoveries and examines the living qualities of the plants and how the essences are made. The result is remarkable.

It is a 'trumpet call' to attend to nature in a new way.
