I decided to try local bee pollen to for seasonal allergies this spring. I started taking bee pollen a few weeks before everything started to bloom as a preventative measure. I have noticed significant improvement over my allergies in the past.
Here is a link about the benefits of bee pollen for allergies (as well as helping many other issues): http://www.shirleys-wellness-cafe.com/bee.htm
*** Note: If you are allergic to bees, I would not take bee pollen. ***
