Materials
When cast, this spell makes spoiled, rotten, poisonous, or otherwise contaminated food and water pure and suitable for eating and drinking. Up to 1 cubic foot of food and drink per level can be thus made suitable for consumption. This spell does not prevent subsequent natural decay or spoilage. Unholy water and similar food and drink of significance is spoiled by purify food and drink, but the spell has no effect on creatures of any type nor upon magical potions.
The reverse of the spell is putrefy food and drink. This spoils even holy water; however, it likewise has no effect upon creatures or potions.

從以上幾個版本可以看到，除了ODND以及5E外，其他都有提到不允許對任何類型的生物施放此法術這句話。
所以我的結論是：DND5E是大膽融合遠古規則與現代創新的突破性遊戲，我●●吹爆! (X)
