Ayurveda, a Sanskrit word signifying science and art of balanced living, is a system of traditional wholistic medicine native to India . The earliest scriptures on this medical system appeared during the Vedic period in India in the mid-second millennium BC. The Suśruta Saṃhitā and the Caraka Saṃhitā are the two great encyclopedias of medicine compiled from various sources from the mid-first millennium BC to about 500 CE. They are among the foundational works of Ayurveda. Over the following centuries, Ayurvedic practitioners developed a number of medicinal preparations and surgical procedures for the treatment of various ailments. Today Ayurveda is enjoying a new renaissance, gaining popularity not only in India but also in many western especially European countries. It is often successful in cases where modern medicine fails.
