Ayurvedic medicine has a rich history. Originally shared as an oral tradition, Ayurveda was recorded more than 5,000 years ago in Sanskrit, in the four sacred texts called the Vedas: the Rig Veda (3000-2500 BCE), Yajur Veda, Sam Veda, and Atharva Veda (1200-1000 BCE).
Ayurvedic theory states that all areas of life impact one’s health, so it follows that the Vedas cover a wide variety of topics, including health and healthcare techniques, astrology, spirituality, government and politics, art, and human behaviour.
Ayurvedic medical books, available by the eighth century BCE, provide not only procedural instructions but also a history of how Ayurvedic medicine evolved over time. Current knowledge about Ayurveda is primarily based on “the great triad” of texts called Brhattrayi, which consists of the Charak Samhita, Sushurta Samhita, and Ashtanga Hridaya. These books describe the basic principles and theories from which modern Ayurveda has evolved.
