All of these various strands of knowledge culminated in his research of flower essence therapy as a “living science of Nature,” requiring an accurate understanding of subtle qualities of plants, and also of the mental and emotional realms within the human being. After working extensively with the original English repertory of Dr. Bach, Richard went on to pioneer, since 1978, the development of flower remedies from North American plants, which are now recognized and used throughout the world. He specializes in FES botanical studies, and photographs many of the FES flowers.
