Bee Pollen for Allergic Rhinitis

The idea that local bee pollen desensitises hay fever is popular and largely untested; the pollen bees collect is mostly not the wind-borne type that causes symptoms.

Proposed oral tolerance induction through repeated low-dose antigen exposure, plus flavonoid-mediated mast-cell stabilisation - neither demonstrated in human allergic rhinitis trials.

Allergic rhinitis is driven overwhelmingly by wind-pollinated (anemophilous) plants: grasses, ragweed, birch. Bees collect heavy, sticky entomophilous pollen from insect-pollinated flowers, so a local pollen product usually contains little of the antigen actually causing symptoms. The oral tolerance rationale is real in principle - it underpins sublingual immunotherapy - but SLIT uses standardised, quantified, escalating doses of specific allergens under supervision, none of which describes a jar of granules. No randomised controlled trial has shown bee pollen reduces rhinitis symptom scores. Meanwhile, case reports document anaphylaxis, eosinophilic gastroenteritis and severe reactions in pollen-allergic people after ingesting bee pollen, which is a poor risk-benefit trade in a condition with effective, cheap, proven treatments.

Anyone with confirmed grass, ragweed or tree pollen allergy should use standardised immunotherapy instead.
