The earliest written reference to the consumption of fungi as a medicine, rather than a food, is within the Sanskrit hymns contained in Rig veda, which forms a part of the oldest sacred texts of Hinduism, the Vedas. In one of the hymns (Book 8, hymn 4, stanza 3) 'Soma' is described as an inebriating ritual drink, which was thought to infer divine powers on those who drank it:

We have attained the light, the Gods discovered.
Now what harm may foeman's malice do to harm us?
What, O immortal, mortal man's deception?
The drink of the Gods
