As per Ayurveda, the human body consists of three primary life forces or biological humors, which are Vatha, Pitha and Kapha. These three doshas are called the tridoshas. Good health is the balance among these life forces. Any imbalance among the tridoshas causes a state of unhealthiness or disease. The main position given to humoral equilibrium indicates its importance in maintaining health. Any disequilibrium is considered to lead to disease. Health is the physiological maintenance of all the functions of the living beings, while disease is the disturbance in the physiology.

Ayurveda is also considered as ‘Science of life’. This makes it the earliest medical science having a positive concept of health to be achieved through a blending of physical, mental, social, moral and spiritual welfare. According to the ancient books of knowledge, health is considered to be a prerequisite for achieving the supreme ends of life consisting of righteousness, wealth, artistic values and spiritual freedom. Preventive and curative aspects of diseases are considered as important components of the concept of positive health.

Ayurvedic Treatments deal elaborately with measures of healthful living during the entire span of life and its various phases. Besides dealing with principles for maintenance of health, it has also developed a wide range of therapeutic measures to combat illness. These principles of positive health and therapeutic measures are related to physical, mental, social and spiritual welfare of human beings. Thus Ayurveda became one of the oldest systems of medicine dealing with both the preventive and curative aspects of life in a most comprehensive way.
