people also take antihistamines. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6074882/
One of the major problems is that you don't know when the honey was stripped from the hive, it could be a time when the bees weren't gathering nectar from what you're allergic to, one reason I thought that pollen might be more effective in my case (eyes swollen shut, I was desperate). No dice. It has a somewhat shorter shelf life than honey, we kept it refrigerated.
Avoiding upstate NY in the fall was one strategy. Living on the coast with daily sea breezes was another. Eventually, moving to NM did the trick, desert allergies are much milder. I had to take the geographical cure. If honey works for you, good for you. It did nothing for me, antihistamines or not.
This old chestnut is like a lot of herbal, vitamin, and other health food curatives, it's fine for mild illness and won't harm you. It just doesn't work for everyone.
If you have a favorite health food store, look for the pollen. A teasponnful is a nice snack--sweet, nutty, crunchy and with a flavor all its own. Since honey is your cure, this might be even better.
