DC is correct, honey contains botulism spores and infants aren't able to digest them before they get sick from them. My doc and all the books say one year is the time when their tummies are fully developed and it is safe. I did wait about another month with mine, just to be on the safe side.
I have never heard that about the allergies. In fact, I have heard the opposite- honey that is locally grown will help your body build up immunities toward the allergens in your area. I have heard if you have allergies you should eat/drink locally grown honey. If allergies are a concern for you, I guess I would check with you pediatrician to see which is correct.
