Ayurveda of India is the world's oldest system of healing and revitalizing the body practiced by the spiritual Rishis, who laid the foundations of the Vedic civilization in India, by organizing the fundamentals of life into proper systems. Vedas, especially the fourth Vedas namely Atharvaveda, are the main source of knowledge in this field. Thereafter, the art of Ayurveda had spread to Tibet, China, Mongolia, Korea and Sri Lanka, carried over by the Buddhist monks traveling to those lands. Ayurveda therefore is not simply a health care system but a form of lifestyle adopted to maintain perfect balance and harmony within the human existence that go into the making of the constitution of each individual, called Prakriti. Ayurveda thus offers a unique blend of science and philosophy that balances the physical, mental, emotional and spiritual components necessary for holistic health.
