Mahavogga 6.6

1. Now at that time the Bhikkhus who were sick had need of fruits as medicine.

They told this thing to the Lord Buddha.

'I allow you, O Bhikkhus, the use of fruits as medicine--the vilaṅga, the pippala , and marika   peppers; the harîtaka , and vibhîtaka , and âmalaka  myrobalans; the gotha fruit ; and whatsoever other fruits are used for medicine, and impart an appetising flavour to foods, either hard or soft, which the sick Bhikkhus could not otherwise eat. They may be received, and stored up your life long; and, if there be necessity, they may be. eaten. If eaten without necessity, (the Bhikkhu who uses them) is guilty of a dukkata offence.'
