Since honey is produced by bees, and bees are not a kosher species, how can honey be kosher?
The Aish Rabbi Replies:
The Talmud (Bechoros 5b) asks your very question! The Talmud bases this question on the principle that “whatever comes from a non-kosher species is non-kosher, and that which comes from something kosher is kosher.”
So why is bee-honey kosher? Because even though bees bring the honey into their bodies, it is not a 'product' of their bodies – i.e. it is stored, but not produced there. (see Shulchan Aruch Y.D. 81:8)
By the way, the Torah (Deuteronomy 8:8) praises the Land of Israel as "flowing with milk and honey." But it may surprise you to know that the honey mentioned in the verse is actually referring to fig-honey!
