Miruvor (3.5e Equipment)
From D&D Wiki
This elven decoction of silvery syrup provides great benefit. A single ounce of this liquor provides refreshment and invigoration (as if the quaffer had rested for eight hours), relieving such conditions as fatigue and exhaustion. A spellcaster must still rest for 8 hours before regaining spells, however. Finally, it restores vigor and health to the drinker, curing 4d8 HP. A typical bottle of Miruvor contains 40 ounces of this prized elven liquor.
