Ayurveda is the collection of principles of healthy living that evolved from times of appearance of man on earth. The antique Vedic texts have scattered references of Ayurvedic Remedies and allied aspects of medicine and health. Ayurveda is an age-old way of life and an ancient system of medicine that operates in tune with nature making it a more wholistic and natural healing technique that believes, there is a definite relationship between illness and the metaphysical state of an individual. Its approach to medical treatment is in stark contrast to the modern medical system, in treating the individual rather than the disease.
Universe as well as human body are made up of five basic elements collectively called Panch Mahabhootas. These are Aakash (Ether), Vayu (Air), Agni (Fire), Aapa (Water) and Prithvi (Earth). The sixth mandatory component of life is Atma (life spirit) without which life ceases. The human body is made up of Doshas (Bio-humours), Dhatus (Body matrix) and Malas (extractable products). Vata, Pitta and Kapha, known as Tridoshs are physiological entities of the body which are responsible for carrying out all the functions of the body. Dhatus are the structural entities of the body. These are Rasa (Plasma), Rakta (Blood cells), Mamsa (Muscular tissue), Meda (Fatty tissue), Asthi (Bony tissue), Majja (Bone marrow) and Shukra (Hormonal and other secretions of genital). Agni (Metabolic fire) is in thirteen different forms and carries out the whole metabolism of the body. The waste products of the body which are extractable are produced in the body as bye-products of metabolism. These are known as malas which include pureesh (faeces), Sweda (sweat) and Mutra (urine). All bio-transformations within the body occur through Srotasas (body channels) which are the sites for action of agni.
As per Ayurveda, Health is a state of equilibrium of normal functions of doshas, dhatus, malas and Agni. It means that when Dosh - Dhatu - Malas and Agni are constantly in a state of functional equilibrium, then the health is maintained. Otherwise distortion of the equilibrium results into diseases. Erratic lifestyle is believed to be one of the basic causes behind the failure of mechanism of maintaining equilibrium. Treatment either with or without drugs and application of specific rules of diet, activity and mental status as described, disease wise, brings back the state of equilibrium i.e. health.
