Horn o' plenty

The Horn 'o' Plenty is a healing potion that can be re-used limitlessly and is never consumed. It still causes Potion Sickness, so pauses are required between uses. It is always dropped by Turkor the Ungrateful, a Boss.

Trivia
In real life, a Horn of Plenty or Cornucopia is a mythical symbol of abundance and nourishment commonly associated with the Thanksgiving season.
