2 Ayurvedic approach of Health Ayurveda is a name which the Ancient Indians gave to their science of medicine. Ayuh means life and Veda means knowledge. Therefore Ayurveda is a science by the knowledge of which life can be prolonged and its nature can be understood. In a broader sense, Ayurveda like Dharma (religion) is not decompartmentalized; ; it includes the adaptation of customs, traditions, ethics, hygiene and medicine.

3 Subject Matter: The fundamental concept is mainly based on Samkhya and Nayaya Vaisheshika system of Indian philosophy. Subject matter is scattered in Vedas, Upanishads and other Classical literature. Charaka Samhita, Sushruta Samhita and Ashtanga Samgrah are three important Medical Texts.

4 Ayurvedic concept of Health is based on Tridosha Theory. Tridosa is biological entity responsible for structural, functional and behavioral dimensions of the living organism. Doshas are two types - Manasik (Psychic) Sattva,, Raja & Tama Sharirika (Somatic) Vata, Pitta & Kapha Sharirika and Mansika dosas are interacting each other therefore, psychosomatic interaction is responsible for maintenance of physiological homeostasis.

6 SIGNIFICANCE OF PRAKRITI IN CLINICAL MEDICINE 1) Promotive Health 2) Preventive Health a) Clinical application of constitution study (Prakriti) b) Identification of Risk Factors c) Course, Complication and Ultimate prognosis of the disease. d) Drug body interaction

7 FACTORS RESPONSIBLE FOR HEALTH AND DISEASE 1) Society at risk a) Rural urban differences b) Economic status c) Education & Profession 2) Family at risk a) Structure of Family b) Familial diseases c) Social stress (marital tension, Strained interpersonal relationship, Poor religious affiliation ) 3) Individual at risk a) Psychosomatic constitution b) Individual habits

8 Ayurvedic approach of therapy Promotive Preventive Curative i. Non-Pharmacologic procedures: Diet, exercise, yogic-meditation relaxation practices, observance of sadvritta (socio- cultural conduct) as per doshik setup, and circadian and seasonal variation.

9 ii. Pharmacologic: : plant based single and poly herbal preparations. ii. Pharmacologic Herbo-metallic preparations: Bhasma: : Powder of a substance obtained by calcination is called Bhasmas.. It is applied to metals and minerals and animal products Rasa-Yoga: Preparations containing minerals as main ingredients are called Rasa-yoga. Abhrak (Mica), Makshik (copper-pyrites) pyrites), Swarna (gold), Rajat (silver), Tamra (copper), Kamsya (Bell metal) etc. Rasa Aushadhi: Preparations containing metals, minerals are considered rasa-aushadhi aushadhi:

10 Mercury, Arsenic, Lead, Zinc, Tin, Iron, Sulphur & Copper are mainly utilized for the preparation of Ayurvedic formulations. Metals are generally toxic in its native form. Several methods have been described for detoxification of metals & minerals in classical literature of Ayurveda. Documentation of the classical preparation along with their ingredients including history of use. Identification of new compound (herbo( herbo-metallic) showing therapeutic efficacy. Standardization of classical procedure by following objective parameters. Biological standardization of the product along with evaluation of safety and efficacy profile.

41 Conclusion Ayurveda has adopted holistic approach. It includes the entire spectrum of life. The object is to enhance longevity. The application of fundamental principles of Ayurveda is helpful in the prevention and management of various mental and physical disorders. The non-pharmacologic procedures include observance of good conduct and practice of relaxation, meditation and other yogic practices in order to maintain the positive health. In Ayurveda various metal and minerals are used for the prevention and management of various diseases. The metals are modified in a new compound which have therapeutic potentials.
