Full text: 

Ave verum corpus factum
Sine viri semine.
Ave verbum patris natum
Ex Maria virgine.

Christi sanguis ave, caeli sanctissime potus.
Unda salutaris crimina nostra lavans.

Caro cibus, sanguis potus
Manes tamen Christe totus
Sub utraque specie

Ave mater salvatoris,
Vas electum, vas honoris
Vas caelestis gratiae.

Salve rosa sine spina
flos es florum.

In hac valle nos protege,
O Maria tu nos pasce
Et hora mortis suscipe.

English translation: 

Hail true body created
without seed of man.
Hail word of the father born
from the virgin Mary.

Blood of Christ, hail, most holy drink of heaven.
Wave of salvation washing away our crimes.

Flesh becomes food, blood becomes drink,
yet, you still remain completely Christ
in both natures.

Hail, mother of the Saviour,
chosen vessel, vessel of honor,
vessel of celestial grace.

Hail, rose without thorn,
you are the flower of all flowers.

In this valley protect us,
O Mary nourish us
and receive us at the hour of death.
