The publisher:
The earlier two volumes of An Insight into Plants described twenty-one Families with how to come to the common sensation of each family and how each remedy in a family could be classified into a specific miasm, thus making a kind of grid of the families and miasms enabling Practitioners to choose a remedy. Consequent to the publication of these Volumes, several colleagues of Dr. Rajan Sankaran from different parts of the world have applied these remedies using this method in their practice with very encouraging results. They have been sharing their cases with Dr. Sankaran and these cases along with his own have not only helped to confirm the ideas in the earlier volumes but they have also made the understanding of these families clearer and more comprehensive. We also could add some more remedies mentioned below into the tables thus filling some of the gaps.
Dr. Sankaran felt it would be really worthwhile to bring out these cases along with the more updated understanding in a book form. Meanwhile, the understanding of some other families has been developing and getting confirmed in practice. These include:

(1) Brassicaceae / Cruciferae, (2) Carnivorous plants (3) Dioscoreaceae (4) Fungi , (5) Piperaceae (6) Rosaceae & (7) Rutaceae

And there was a demand that a third volume of Insight is brought out with the newer families. This volume includes the more updated understanding of the earlier families along with some illustrative cases, especially of rare remedies, from Dr. Sankaran and his colleagues as well as new families with their sensations, miasms and illustrative cases.
