Cucumber

Ibn Qayyim in "Medicine of the Prophet" said, of cucumber that, "The Prophet, peace be upon him, used to eat cucumber with ripe dates. Cucumber is cool and wet in the second degree [see: food qualities] and it cools the hotness in the stomach, it does not spoil quickly and helps relieve prostate pain. [It] helps relieve nausea while its seeds are a diuretic … [it] does not digest easily and its coolness sometimes hurts some parts of the stomach. Hence, one should eat cucumber with what would make its coolness and wetness milder, just as the Prophet did by eating ripe dates with it. In addition, eating it with raisins or honey makes it milder on the stomach.”
