Cum autem oleum olivarum, quod hucusque ad valorem Sacramenti conficiendi praescribebatur, in nonnullis regionibus deficiat vel difficile comparetur, decrevimus, petentibus pluribus Episcopis, ut, pro opportunitate, etiam aliud oleum in posterum adhiberi possit, quod tamen e plantis sit expressum, utpote oleo ex oliva similius.
Further, since olive oil, which hitherto had been prescribed for the valid administration of the sacrament, is unobtainable or difficult to obtain in some parts of the world, we decreed, at the request of numerous bishops, that in the future, according to the circumstances, oil of another sort could also be used, provided it were obtained from plants, inasmuch as this more closely resembles the matter indicated in Holy Scripture.vatican.va vatican.va
