Are there ANY homeopathic remidies for asthma?

i am 16 and have had asthma my entire life but this year it is killing me. I have been coughing wheezing etc for going on a month now. my rescue inhaler doesnt do anything to relieve symptoms and the doctor put me on advair but that has yet to make any difference either. i tried the cough drops and all of that but nothing helps. im just looking for some more ideas so i can get back to my life :(
