I’ve heard that eating raw honey can help prevent pollen allergies - at first glance it makes a kind of sense because raw honey might contain pollen, perhaps processed to some extent by the bees, and maybe ingesting it could build immunity to the kind of reactions some of us get to pollen. But I have no idea if there’s any truth to it.
It has to be local honey with bees taking nectar from the plants you are allergic to. Make sure the beekeeper is selling you pure local honey produced during the spring nectar flow. Honey comes from the nectar. Pollen is used to feed the brood larvae.
As a homeopathic remedy, the nectar contains allergins that stay in the unprocessed honey. Eating the honey lets you build up some immunity. Much like the Indians who would chew a small amount of poison ivy leaves or the mountain folk who would put it in their tea.
