Charaka wrote: "Everything in the universe has medicinal application". Agnivesha told his teacher that he was not able to locate any plant without medicinal application. Before the advent of modern medicine, man was completely dependent upon medicinal plants for curing as well as preventing diseases. Ancient scholars preserved these work on medicinal plants in the form of Nighantus. Later on, the subject Dravyaguna came in existence, and it has significant place in Ayurvedic system of medicine. Scholars of the western countries wrote Materia Medica, the term coined for the subject dealing with study of drugs derived from natural source. Matreria Medica has been largely replaced by term Pharmacognosy.
Dravyaguna deals with study of drugs derived from natural (plant, animal or marine) origin. In the recent past, the study of Dravyaguna has become more important because of global acceptance of Ayurvedic system of medicine. Ayurveda has its own concept as far as drug formulation is concerned. Ayurveda has documented Dravya, Guna, Rasa,Virya, Vipaka, Prabhava and Karma for all medicinal agents and these represent the pharmacological aspects of drugs used in Ayurveda.
This book has been written with inputs from indispensable works like Pharmacographia Indica, Nadkarni's Materia Medica and Dravyuguna Siddhanta and journals dealing with medicinal plants and natural products. Chemistry and pharmacological studies have been included to make reader familiar with latest work being carried on Indian medicinal plants.
