The origin of Ayurveda dates back to more than 5000 years. It is said to be as old as humanity itself. It is thought to have come to the earth from heaven’s abode for the well–being of God’s creations. Thus, the science itself is eternal with no beginning and no end. One of the principal tenets of Ayurveda is that life is eternal, therefore, as life is eternal, so its science should also be eternal.
The eternity of Ayurveda is also described in the Charak Samhita (one of the scriptures in Sanskrit language).
It says that Ayurveda is eternal because of following reasons
It has no beginning.
It deals with things which are inherent in nature.
Such natural manifestations are eternal.
Historians believe that the documentation of Ayurveda started around 5000 years ago. Prior to this Ayurveda was preached and practiced orally. Hindu mythology states that this knowledge was passed on by Brahma (the father of the gods and mankind) to Indra (the king of gods) who then passed it on to a sage called Bhagirath for the benefit of men on the planet.
