According to Ayurveda, health is not merely considered to be a state of freedom from ailments or diseases, but rather a state of enjoying uninterrupted physical, mental and spiritual happiness and fulfilment. Ayurveda originated as a part of Vedic science. This is an integral spiritual science devised to give a comprehensive understanding of the entire Universe which it sees as working according to a single Universal Law. Vedic science includes Yoga, Meditation and Astrology and set forth Ayurveda as its branch for dealing with physical body and includes herbal medicines, dietetics, bodywork, surgery, psychology and spirituality.

The concept of pathogenesis in Ayurveda is basically different from the modern medical science. Ayurveda defines health as the state in which the Dhatus are in equilibrium and if this balance is disturbed disease is caused. Therefore the prevention of vitiation of the Doshas (3 biological forces) is the first step in prevention of diseases whether exogenous, endogenous or mental in nature. Natural immunity is always available to us if we eat according to our Prakruti.

In Modern medicine more attention is paid to correct the afflicted part of the body. But in Ayurveda while treating a disease, the individual as a whole is taken into consideration. Not only the condition of other parts of their body, the condition of their mind and soul are also taken into account while treating. So once the root of the disease is cured, chances of recurrence of the disease are rare.

Ayurveda diagnostic procedures are two pronged, the first is aimed at establishing the state and type of pathology with examination of the person the second is to decide the mode of treatment to be applied based on the strength and physical status of the individual. The former and make different investigations to diagnose the disease.
