Whether the components are actually consumed for this spell seems unclear--would casting it actually use up and totally consume an entire 50 gp/ 8 lb item of alchemist's supplies? Or can the caster simply use a component pouch or spellcasting focus as usual?
The cost is equivalent to a Common magic item such as a basic Potion of Healing (50 gp), but the fact the Elixir vanishes after 24 hours would seem to indicate it isn't meant to be a replacement for the real thing, and thus may not have the same cost.
