The Vedas are considered the earliest literary record of Indo-Aryan civilization. It is the most sacred scriptures of India.

There are four Vedas in Hinduism. They are:

1. The Rig Veda,

2. Sama Veda,

3. Yajur Veda and

4. Atharva Veda.

Most ailments, both physical and mental, were attributed to malevolent spirits and cures consisted of rituals, charms, mantras, medicines and surgical intervention.

The hymns in the Atharva Veda, the last of the four Vedas, and largely composed after the Aryans were well settled in the sub-continent, indicate that indigenous non-Aryan healing practices had influenced the Vedic Aryan healers.
