The book catalogues and compares trends which pervade the entire Botanical hierarchy of families, orders and clades and places them into stage tables which are based of the previous work of Dr. Scholten (stages) and Dr. Sankaran (miasms).

In this book I unearth aspects of Psychology which can enrich the stage concept with various perspectives and methods, such cluster analysis which have the potential to provide a more quantitative evaluation. This means that the stage concept can be applied to any remedy or case, regardless of the Kingdom.

Another challenge, implicit in any Botanical study of Materia Medica, is to integrate any causal relationships between the evolution of botanical function in each of these groups and the symptoms they produce into the remedy pictures.
