There is a fake Hadith that states that eggplant materializes the goals anticipated from eating it. This statement is not suitable to be related from a sane person let alone the Prophet.
There are two types of eggplants: white and black. There is a difference of opinion on if it is hot or cold, although we think it is hot. Eggplants cause black bile, piles, clogs, cancer and leprosy. Eggplants In addition spoil ones color, make it black and cause bad breath. White eggplants do not have these side effects.
