I have heard of it, but I'm not sure I buy it. Growing up, honey came from the supermarket and I had no allergies. In San Diego, honey came from the supermarket and I had no allergies. Here, most of my honey comes from the farmers market and I have horrid allergies. Now, granted, it may be that the honey comes from a rural area 25-30 miles away from where I live and not from a hive in my own back yard where it's precisely the same mixture of plants that I'm dealing with, but I have not found anyone here in the middle of the Concrete Jungle who makes honey closer to home.
