Minecraft wiki entry for Village_mechanics, associated text: Players can cure Zombie Villagers by using a golden apple on them while they are affected by weakness. Players can usually apply weakness by brewing potions. In Nether-disabled servers, a witch and a zombie villager, or weakness tipped arrows from a master fletcher are needed. Witches sometimes throw a splash potion of weakness (if a player is within 3 meters), which they can use to their advantage.
