Minecraft wiki entry for Witch_farming, associated text: Witches are hostile mobs that drop all kinds of loot. Their normal drops are redstone, glowstone, sugar, gunpowder, glass bottles, spider eyes, and sticks. The sticks are dropped twice as often as the others. Players can cause a witch to drop the potion they are currently using, usually instant health. The Looting enchantment increases the chances and output of each drop.
