i make mine, well, not exactly in bulk but a small-ish container's worth at a time. i don't keep it in the fridge most of the time as i take it with (and i stay at SO's up to half the nights a week). it's a mix of NOW cocoa butter lotion and alcohol-based tinctures of fennel and wild yam. i wonder if it goes bad? i shake it up before each use so i wouldn't be able to tell if it started growing a little mold or something like that... it smells the same still but for some odd reason i became suspicious

Alcohol usually works as a preservative so it should last longer than if you didn't have alcohol based tinctures in it.
