This is an old post, so perhaps you've already found someone. If not, please email me. I work with asthma and allergies (and a lot of other illness) over here on the Seattle side, if that's not too far. If it is, I can recommend a good east-side naturopathic physician.
Also, just to clarify what another poster said about this being a serious disease, and not to leave it to altnerative medicine. It absolutely is a serious disease! Which in no way diminishes the power of natural medicine to treat it. Asthma is very often associated with a systemic underlying inflammatory process, and/or allergies. These things can absolutely be treated naturally. This is not at all to say that conventional medications should be excluded. They also should be part of any well-rounded asthma management plan. In Washington, naturopath doctors are trained and licensed as primary care physicians, with broad prescriptive rights, and as such are well versed in asthma management and other chronic disease. My approach is to put a full program in place which advisess which treatments to pursue, depending on what stage the asthma is in. There are daily foods, herbs and supplements that nourish the body and reduce inflammation, to lessen the chance of a flare-up or asthma attack. There are herbs to take if and when breathing becomes difficult, but is not in asthma attack mode. And then there are pharmaceutical medications on board in case an asthma attack develops, because dogma has no place in medicine - if you can't breathe, you take a drug that helps you do so! However, that last step should not be the daily approach, as long-term use of steroids can and does have long-term health repercussions. So a strategy that reserves them for when necessary, while building overall health to reduce how often they become necessary, is the wisest way.
With best wishes for all of us to build luminous good health,
