There's no scientific evidence that eating honey helps build any resistance to pollen allergy. Both because ingesting it doesn't expose you in any meaningful way to pollen grains as the stomach acid breaks them down almost immediately and also because most of the pollen that causes allergies is grass and tree pollen that's spread on the wind, rather than flower pollen which is spread by bees.

But, yes, local honey does have other benefits beyond allergy symptoms and is also delicious.
