Not sure if this will help you but I have asthma and I'm very very allergic grass, trees, dust, cats, dogs, ragweed and the list goes on. I used to do the allergy shots but they did nothing for me and made me feel like crap. For 2 years now I have been drinking 2 cups of allergy herbal tea a day sometimes more because it's tasty lol. But two cups is enough to bring down any reactions I am having and I pack some allergy pills on the side just incase. It has worked wonders for me and is really good during the tree and grass season where I become super allergic to Thane.
