Dravya Guna Vigyana (Materia Medica)
Creating landmarks in the field of Ayurveda Since….1944 DRAVYAGUNA DEPARTMENT BRIEF INTRODUCTION: It’s a complete science of herbal plants. It’s including pharmacognosy, pharmacology and therapeutic uses of the plants. Ayurvedic drugs, especially herbs are prescribed in different pharmaceutical forms, to get maximum therapeutic effect. The word dravyaguna consist of 2 words: 1) Dravya = material of thing which can be living or not living. 2) Guna = properties According to Charaka their is nothing on the earth which is not medicine. That’s why Ayurveda considers all substances as medicine, if used for specific purposes in an appropriate way. In Ayurveda more than 600 medicinal plants are included as drugs and they are used either alone or in combination with each other to alleviate the disorders. Ayurveda takes into the account the action of the drug in its entity. It holds that the action of the whole drug is often different from that of any one of its constituents considered separately. In this regard, the quotation from the Charaka Samhita looks more interesting- “ It is not possible to infer the action of a compound substance on the particular combination of doshas. To understand the Ayurvedic mechanism of action of any drug, it is essential to have the knowledge of- rasa (taste), guna (properties), virya (biological properties), vipaka (attributes of drug assimilation) of that specific drug. Use of herbs as medicine by the sizeable number of population has drawn the attention of Health planners of developed and developing countries around the World and also of World Health Organization (WHO) to address issues related to "safe, standard and quality" products based on medicinal plants.
