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.
