Ayurveda is the oldest surviving complete medical system in the world. Derived from its ancient Sanskrit roots - ‘ayus' (life) and ‘ved' (knowledge) – and offering a rich, comprehensive outlook to a healthy life, its origins go back nearly 5000 years. It was expounded and practiced by the same spiritual rishis, who laid the foundations of the Vedic civilisation in India, by organising the fundamentals of life into proper systems.

The main source of knowledge therefore remains the Vedas, the divine books of knowledge they propounded, and more specifically the fourth of the series, namely Atharvaveda that dates back to around 1000 BC. Of the few other treatises on Ayurveda that have survived from around the same time, the most famous are Charaka Samhita and the Sushruta Samhita which concentrate on internal medicine and surgery respectively. The Astanga Hridayam is a more concise compilation of earlier texts that was created about a thousand years ago. Between them, they formed a greater part of the knowledge base on Ayurveda as it is practiced today.

The art of Ayurveda had spread around in the 6th century BC to Tibet, China, Mongolia, Korea and Sri Lanka, carried over by the Buddhist monks traveling to those lands. Although not much of it survives in original form, its effects can be seen in the various new age concepts that have originated from there.
