I drink hot peppermint tea when I am feeling tight. Really helps to open up the air ways. Although if you have acid reflux, it may not be such a good idea. I drink it anyway, the benefits to my asthma out weight the reflux problems.
I also use an oil from the health food store to help open my nose if it's stuffy. I don't believe I can give the name on here. I found it at a famers market and it also helps with aching joints to rub it on. If I am feeling like I won't be able to get to sleep right away, I also rub it on my sinuses and forhead , some how it helps me to go to sleep better. If you want the name you can email me, but please write from the asthma forum on the subject line. I will not open any mail up if I don't know who it is.
Good luck, but try the peppermint tea. I have also made a tea out of elderberry, peppermint and euclyptus. tastes good and is good for the immune system too.
