The history of indigenous Indian health science is probably as old as the Indus Valley Civilization
dating back to 3000 BC. The remains of deer antler and bitumen found in Harappa testify to the existence of a medical science.
The Atharva Veda has many hymns eulogizing herbs
. The Atharvan hymns chanted for the cure of diseases were known as ‘Bhaishajyam’ and those for attaining longevity and prosperity were called Ayushyam. These hymns, especially the Ayushyams are considered to be the foundation for advances in later medicine.
