Honey is produced by honey bees returning to their hives with nectar and pollen spores. The resulting honey that is produced by the honey bees is stored in covered wax honeycombs until the bees are ready to use it for food... or until a beekeeper enters the hive to remove the honey-filled combs found within.
Exactly what does this have to do with your runny nose, watery eyes and scratchy throat?
Almost all evidence regarding the immunizing effects of eating honey is anecdotal. Even though there have been no significant scientific studies that have conclusively proven whether honey actually reduces allergies - these reports have proven persuasive enough for some people to try to fight their seasonal allergies by eating honey every day.
The prevailing theory is that eating local raw honey works like a vaccination. Vaccines introduce dummy versions of a particular virus or germ into the body and effectively trick it into believing it's been invaded, triggering an immune system response. This produces antibodies designated to fight off the foreign invaders. When the body is actually exposed to the harmful germ or virus, the antibodies are ready for them.
Honey may gradually expose the body to allergens, which could immunize a person against allergies. The idea behind eating honey is similar to gradually vaccinating the body against allergens, a process called immunochemistry. Honey contains a variety of the same pollen spores that give allergy sufferers so much trouble when flowers and grasses are in bloom. Introducing these spores into the body in small amounts by eating honey should make the body accustomed to their presence and decrease the chance an immune system response like the release of histamine will occur.
Since the concentration of pollen spores found in honey is generally low -- compared to, say, sniffing a flower directly -- then the production of antibodies shouldn't trigger symptoms similar to an allergic reaction. Ideally, the honey-eater won't have any reaction at all. As innocuous as honey seems, it can actually pose health risks in some cases. Honey proponents warn that there is a potential for an allergic reaction to it. And since honey can contain bacteria that can cause infant botulism, health officials warn that children under 12 months of age whose immune systems haven't fully developed shouldn't eat honey at all [source: Mayo Clinic].
If a regimen is undertaken - local, pure, raw (unprocessed, i.e. unheated beyond 100-108 degrees F - temperatures that may be naturally reached inside beehives) wildflower honey is generally accepted as the best variety to use. Local honey is produced by bees usually within a few miles of where the person eating the honey lives. This proximity increases the chances that the varieties of flowering plants giving the allergy sufferer trouble are the same kinds the bees are including in the honey they produce. After all, it wouldn't help much if you ate honey with spores from a type of plant that grows in Florida if you suffer from allergies in New Jersey. There's no real rule of thumb on how local the honey has to be, but some proponents suggest the closer, the better. Others claim that since flowering species in the northern 2/3s of New Jersey are pretty much identical, any pure, natural, raw wildflower honeys from that region will do.
It is recommended that you do some research yourself -- you can use any of the search engines to get relevant information from the internet... remember, much of what you'll see is anecdotal.
