question on home remedies

[blowry]

Plain steam hasn't worked for him...I told him to try putting vicks in the hot water and then a towel over his head but, he has VERY sensitive skin and breaks out from EVERYTHING!! I feel so bad for my Dad.....I went on line to see if I could find some kind of home remedy but I dont' know how to phrase the question..he does have a somewhat loose cough but just can't seem to bring it up...I told him to cough hard and "huck tooey" it out...(YUCK!) but, he said he can't. My Mom is a good nurse...Hopefully this new medication will work..

Thanks for the suggestions girls!
