I have heard that as well.
There is some anecdotal support for honey helping allergy sufferers- perhaps these people are allergic to pollen from clover, fruit trees etc. (plants with showy flowers that bees visit).
It is my understanding that most people are allergic to wind pollinated plants like ragweed and certain grasses- bees don't visit these plants so there would be very little of these types of pollen in honey.
Here is the abstract for a published study on this topic-

In any case, it can't hurt anything to give it a try. If I was an allergy sufferer, I wouldn't mind real improvement in my symptoms OR even the benefits of the placebo effect- either would bring relief
