44 patients with birch pollen-related allergic rhinitis consumed either BPH or regular honey (RH) daily from November to March.
17 patients on their usual allergy medication served as the control group.
From April to May, patients recorded daily rhinoconjunctival and other symptoms, and their use of medication.
The results were encouraging - during birch pollen season, patients who took birch pollen honey (BPH) reported:
- 60% lower total symptom score
- twice as many asymptomatic days
- 70% fewer days with severe symptoms
- they used 50% less antihistamines
Patients who preseasonally used BPH had better control of their symptoms than did those on conventional medication only. The results should be regarded as preliminary, but they indicate that BPH could serve as a complementary therapy for birch pollen allergy.
This study is interesting mainly because previous trials have failed to show benefit of local honey as treatment of allergic rhinitis.

@DrSilge (Robert Silge, MD): interesting. Hard to get the bees to care about anemophilous plants though.
@DrVes: correct, bees are not interested in those - there is no ragweed pollen-honey as far as I know...
