Create healing potion

From Ardrana

The create healing potion spell allows the caster to transform a single flask or bottle of any liquid – be it water, poison, or even another potion – into a standard potion of healing capable of restoring an injured creature who imbibes it. The potion may be carried and used at a later time, but if no one imbibes it before the spell duration expires, it reverts to its previous composition.

Note: This spell originally appeared in this form in Warriors of Heaven for the AD&D game from TSR. Its use here is for the purposes of providing context for the campaign only.
