Preface

The story of drugs goes back to the Prehistoric days. The Indian sages invented drugs and their therapeutic uses long ago. This was based partly on observation of the effect of drugs on various animals and partly on human trial and error. Rgveda, the oldest document of Indian wisdom, contains material which shows the rational attitude towards plant kingdom and its exploitation for the benefit of the humanity. The Atharvaveda has got more advanced picture and a larger number of drugs used in a similar number of diseases. On this long tradition and accumulated wisdom the ancient sages, Atreya and his disciples, after a deep and concentrated effort were able to make some generalisations for rational explanation of drug action which formed the basic concepts of dravyaguria. Evidently this study was going on in different circles of scholars and as such different schools of thought arose. The school of Suaruta has some differences with Atreya's teachings which was followed by Nagarjuna.

The theory of Panca Mahabhuta is the ultimate basis on which the fundamentals of Dray yaguria stand. This is again based on the law of Uniformity in constitution of material bodies including human body on one side and drugs on the other. How to know the Pancabhautic compositions of a drug particularly in its pharmcodynamic aspect ? This was attempted in two ways :— one by linking the Rasa as indicator of the Bhautic composition and secondly by obser-ving the sum total effect on the body. Rasas were percei-ved directly and their effects on the Dosas were also stand-ardised. Then by law of similarity and dissimilarity their-relation witn Bhritas were known by Inference. Thus Rasas are not direct indicators of drug composition but indirect ones through the channel of Dosas. For instance, Madhura Rasa increases Kapha which is Parthivapya in nature, there-fore by law of similarity ( If there is increase, there is simi-larity) Madhura Rasa is taken as Parthivapya and the drug is also taken as Parthivapya. This is again confirmed by law of dissimilarity as it decreases Pitta and Vata which are dissimilar to Ap and Prthvi respectively.

The drugs can' t have effect until they are assimilated and metabolised. it was also observed that there was-distinct change in ingested material during digestion which further effected the metabolic process. This led to formulation of the theory of Vipaka. In some cases the effect could not be explained rationally on the basis of Rasa. For instance, pippali (piper longum) is Katu Rasa which should have katabolic effect on the body whereas reverse effect is seen. This led to infer the transformation of Katu Rasa into Madhura Vipaka.

Drug action was the most important problem to be tackled. This led to the evolution of the concept of virya which was responsible for drug action. There was, however. difference of opinion among scholars regarding the nature of Virya. One group was of conservatives who held potent gurias ( eight or two ) as viryas but Atreya was liberal enough to accept any principle potent enough to produce action as virya. On account of virya, the pharmacodynamics of drugs was brought to rational level and different actions where explained on its basis.
