Hi Everyone, I'm relatively new to this list. There is an audio tape called 
"Asthma, Allergies, and Hay Fever" by Diane Petoskey(a naturopathic doctor I 
think)available through an organization called the Frontrunners.  
www.thefrontrunners.com or 1 800 237 5199. This tape outlines a diet to follow 
with supplements. She mentions the role of food allergies(dairy and gluten are 
biggies)and how to strengthen the whole immune system.
    I have also heard that some people are having good results with magnetic 
necklaces(Nikken magnets seem to be what they were using). I would try both 
approaches. Hope this helps. Susan E.
