Text Book of Dravyaguna

From the preface: Dravyaguna is interpreted as clinical pharmacology since the most of the Ayurvedic drugs were initially evaluated only in human beings. Seers of Ayurveda have collected the information regarding the clinical usage of several herbs from cowherds, shepherds, tribals and other forest dwellers and they never felt the necessity of evaluating their activity in animals. Dravyaguna encompasses the information of all other allied fields of pharmacology like: Namarupa Vijnanam-pharmacognosy the science of identification of drugs. Gunakarma Vijananam-pharmacodynmaics mechanism of drugs action and pharmacokinetics study of absorption distribution metabolism and excretion of drugs. Amayikaprayoga Vijnanam therapetucis branch of medicine concerned with cure of disease of relief of symptoms. Kalpana Vijnanam-Pharmacy science of selection preservation and compounding of drug.
