I've heard of it as a remedy to plucking. That may be related to the allergy thing - bee pollen or honey from local bees can help alleviate allergy symptoms. I give honey to my dogs in the spring and summer. Honey can contain traces of something (salmonella, I think) in teeny quantities that don't affect humans but isn't recommended for parrots, so bee pollen is a great option for parrots. Didn't know they sold it at Whole Paycheck. Will have to make the trip.
