Heart

Hearts are the unit of measurement for health in the Legend of Zelda series. When Link touches a heart, it refills one Heart Container to the maximum number of heart containers Link has at the time. Hearts can be found in the grass, in trees, after a monster is slain, even in some shops.

When Link is injured, a number of hearts are depleted from his total. When Link runs out of hearts, he gets a Game Over. Different monsters drain different amounts of hearts, from a fourth of a heart to more than three full hearts.

Ways to restore his hearts are to find hearts in the places mentioned above, use a Fairy to restore eight hearts, a Red Potion or Great Fairy Tears to restore all of his hearts, various soups for varying amounts, or even with Lon Lon Milk.
