Garlic can be put in a still for holy water

[Egregorious]

To be honest I think there are plenty of recourses for holy water of all things. The chaplain starts with stuff to make it; the bar has the resources to make an infinite amount; if you can source wine from anywhere then you can convince science/medbay to make it for you; and if you have garlic you can ask for access to anywhere that has a reagent extractor from the HoP. Not to mention the fact this is sort of part of botany's job, you can just ask them to grow and extract a bunch of garlic for you; or order it via the chemistry request console thingy.
