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.
Spell as written:
Casting Time: 1 minute
Components: V, S, M (alchemist’s supplies)
Duration: 24 hours
You create a healing elixir in a simple vial that appears in your hand. The elixir retains its potency for the duration or until it’s consumed, at which point the vial vanishes.
As an action, a creature can drink the elixir or administer it to another creature. The drinker regains 2d4 + 2 hit points.
