Just like its sister science, yoga, Ayurveda is a completely holistic system stemming from the Rig-Veda, one of India’s most ancient philosophical texts which is thought to have been written sometime between 4500 and 1600 BC. The text contains a collection of works recorded by many great sages who were concerned about human health and wellness. Much of what these ancient sages believed to be true about human anatomy and physiology has been confirmed these days by modern science.
