I'm sorry I haven't commented sooner but your post sparked a memory and I've been exploring your issue, looking for the safest, most effective way to treat it and believe your best and safest bet is Barbara O'Neill's chopped onion on the bottom of your feet.
I say safest because it won't matter what else you've been doing, taking or trying, it's reported to have immediate respiratory effect and you don't need to know the cause.
Here is one of her videos about it.
Don't leave the chopped onion laying about for long as, apparently, it will collect surrounding germs. Whatever you don't use, put in a jar or glass and cover with honey. Cover the jar/glass and let set for a day, strain out the onion and you'll have an excellent respiratory/cough syrup that will keep for a very long time.
I'm going to go chop some onion of my own now so, tata! Let us know how it goes!
