On this topic, we defer to the opinion of the National Honey Board, which says the following:

There are anecdotal stories of people claiming relief from allergies by eating local honey, but we are not aware of any scientific evidence to support these claims. This subject is somewhat controversial since some experts claim that the kinds of pollens that are the greatest cause of allergies are smaller windblown pollens that are not typically found in honey.

This topic is also covered on the website of the American College of Allergy, Asthma & Immunology’s here.
