Golden Carrot

Golden carrots are a brewing ingredient used to make Potions of Night Vision.

Trivia

 * The golden carrot's use for making the Potion of Night Vision could come from the fact that carrots are healthy for your eyesight (due to large amounts of β-Carotene). During World War Two, the British government explained the success of their night fighter efforts during the London Blitz by claiming that they fed the pilots large amounts of carrots to improve their night vision.  In reality, this was a ruse to cover up the use of the then-new technology of Radar.  But the popular imagination has exaggerated the night-vision benefits of carrots ever since.
