Eggplants: Holy Prophet (saw) and Imam Ali Al-Ridha

Eat eggplant (aubergines).  It is a cure for every illness

Eggplant is good for the black bile and is not harmful for the yellow bile

Give us eggplant, for it is hot in the cold and cool in the heat, it is suitable at all times, and good in every condition.
Imam Ridha (peace be upon him)
