What I have read about this is that in order for this to be effective for allergies, it must not only be local but also contain a portion of the honeycomb in the jar.
It has something to do with being less processed/filtered and containing small amounts of the pollen residue.
It’s supposed to work on the same principle as the weekly/twice-weekly allergy shots, gradual minute exposure to the allergens in question.
If ones primary allergies are to pollens, I can understand that to a degree. But many people have allergies to other substances like molds, etc. So I don’t know how that would work.
