Why industrial value of Dravyaguna needs revival?
Dravyaguna is in a transitional phase with revival of interest in Ayurveda lately. Ayurvedic Materia Medica is a store house of several drugs which need to be explored for possible use in the medicine. Several medicinal herbs mentioned in Nighantu related to Dravyaguna like Bhavprakash Nighantu, Raj Nighantu and Dhanwantry Nighantu need to be properly identified.
Several colleges in India are imparting postgraduate studies in Dravyaguna. Government Ayurvedic College, Raipur, Government Ayurveda College, Trivandrum, India and Government Ayurved College Post-graduate Training & Research Institute, Kadam Kuan, Patna is a few of the government institutes dealing with postgraduate studies in the field of Dravyaguna.

Relationship between Dravyaguna and Regulatory Affairs
Regulatory Affairs have vital role to offer in any system of medicine. With resurgence of the Ayurvedic System of Medicine, Regulatory Affairs have critical role to play so as to meet international standards. A proper knowledge of Dravyaguna is essential for understanding subject content of Ayurvedic Pharmacopoeia of India, Ayurvedic Formulary of India and Essential Drug List of Ayurveda.
Further a Dravyaguna professional need to have exposure to modern subjects like pharmacognosy, pharmacy, pharmaceutics, pharmacology, phytochemistry and ethnopharmacology. Now days, several Ayurvedic manufacturing houses are targeting overseas market for selling. For promoting Ayurvedic products in foreign countries, a Dravyaguna professional should have proper knowledge about regulatory bodies dealing at international level. Preparing common technical dossiers, master drug files, monographs white papers and material safety data sheet are part and parcel of the procedure involved in registration of products in foreign countries.
In postgraduate syllabus of Dravyaguna designed by Central Council of Indian Medicine, topics related to Ayurvedic Regulatory Affairs have been included so as to meet the changing scenario for the Ayurvedic drugs at national and international levels. In postgraduate syllabus of M. Pharm Dravyaguna, emphasis has been given on the industrial significance of Dravyaguna. In our opinion, Ayurvedic professional pursuing specialization in Dravyaguna must acquire knowledge about postgraduate syllabus of M. Pharm Dravyaguna.
Interdisciplinary nature of Dravyaguna
Dravyaguna is basically an interdisciplinary subject. It is worthwhile to note that several Indian medicinal plants are part and parcel of American Herbal Pharmacopoeia (AHP) and British Herbal Compendium (BHC). Scenario for Dravyaguna is changing and it has become an interdisciplinary rather than conventional subject. There is a strong linkage between Dravyaguna and modern subjects like pharmacognosy, phytochemistry and pharmacology. The six taste theory of Ayurveda has significant role in formulating a drug and therapeutics. This has been linked with phytochemistry and it shall be worthwhile to address six taste theories as ‘Traditional Phytochemistry’.
In Western countries the study of medicinal plants for treating diseases is addressed to as phytotherapy or Medicinal Herbalism. An expert medical herbalist is well conversant with traditional and modern medicine and pharmacy subjects. Ayurveda has been addressed as ‘Reverse Pharmacology’. Based on the evidence based approach, Dravyaguna is comparable to ‘Reverse Pharmacognosy’.
Dravyaguna has played a critical role in development of Ayurvedic Materia Medica as well as Herbal Materia Medica. Further, several Ayurvedic drugs are part and parcel of Unani Materia Medica. Further, the knowledge of Dravyaguna has been utilized by modern medicine for discovering life saving drugs. In this regard, Reverse Pharmacognosy approach can be coupled with Dravyaguna on lines similar to ethnopharmacology approach to drug discovery.
Role of Central Council of Indian Medicine in promoting Dravyaguna
The Central Council of Indian Medicine has issued a well-structured syllabus for Ayurvedacharya (B.A.M.S) and MD Dravyaguna courses. The syllabus has been revised from time to time, keeping in mind the growing and changing scenario of Ayurvedic Medicine. The Central Council of Indian Medicine should ensure that minimum standard requirements (MSR) are met with production of institutionally qualified Dravyaguna experts. Re-Orientation Training Programs and Faculty Development Programs in various subjects of Ayurveda is welcome step for improving education standards.
The main question is that whether Ayurvedic institutions approved Central Council of Indian Medicine for postgraduate studies in Dravyaguna are well equipped so as to meet practical requirements of the syllabus. Recent times have witnessed the mushrooming growth of Ayurvedic institutions across India. But the questions is that are we not neutralizing the resurgence and renaissance of Ayurveda by producing postgraduates lacking practical skills and exposure to modern scientific techniques.
