Ayurveda, or the science of long life, is the ancient system of medicine that had been widely practised in the Indian subcontinent for several centuries. Although the term itself does not find mention in the Vedic or Buddhist texts, the principles and practices of Ayurveda were developed from systematic study and practice as embodied in the early Vedic texts to the celebrated Samhitas of the Brhatrayee and the remarkable Buddhist influence in between. It is this exciting journey that Dr.Valianathan retraces in 'An Introduction to Ayurveda'. the book sets to acquaint the readers with the evolution of Ayurveda from being a faith-based system to what is now regarded as a reason-based one. It covers the important branches of Ayurveda, the techniques and instruments that were developed and used. The education and training that was planned for aspiring practitioners are also discussed in lucid and accessible language.
