Surprisingly for me, bee pollen has pretty much halted my (at times severe) hayfever. Initially I took 1 per few days and had an 'internal hayfever' type reaction then soon enough my nose and eyes stopped reacting.
The local pollen cures are bunkum, imo, just teaching your body to deal with pollen in general does the trick. A large dose off any pollen, as found in bee pollen, seems to work wonders when taken regularly in spring. Ymmv, but I've struggled for a long time until recently.
There is sub-lingual immunotherapy available for hayfever. I don't know how much it boosts the immunity to allergens. I'm currently on year 3 of a 5 year course.
Hopefully it works -- does not seem to have had a huge effect so far.
Anecdotal evidence aside, i would not unconsider it that quickly. My research before starting this indicated that effect varies from case to case. However, this was definitively not woo-woo.
Have a read up on the use of hookworms as a suppressant for hayfever and other immune system overreactions.
It seems like there's more work to be done there, and lots of potentially exaggerated stories of big pharma trying to shut research down, but the hypothesis has always sounded sensible to me, and what little formal research I've heard of has been extremely positive.
