yeah it was. I was thinking that Wrenna has something a little like that. it would be a really tiny vial that she keeps on a necklace and hides it under her clothes. Because the vial is so tiny, there's only a little bit of the potion in it (meaning a one time use thing) and it can heal someone who's even on the brink of death. It's semi-important to Wrenna's back story but doesn't have to be there.
