question on home remedies

[blowry]

Hi Girls! I haven't been on in a while...matter of fact I haven't been on YT much lately either!! Hope everyone is doing well!

My Dad has had a terrible cold that he just can't shake...He does have emphazema (sp?) but, he is not on oxygen. Because he is taking meds for hyper tension, meds to thin his blood and other meds for his breathing, (or lack of it) he is very limited as to what he can take. He has had this cough that is loose but just can't bring anything up. He had chest x-rays yesterday and ,THANK GOD!!, his lungs are clear but, he needs something to bring up the phlem (sorry if this sounds discusting) My Mom is picking up a couple more meds that the doctor had prescribed. I would like to him try a home remedy as well...does anyone here have any of "grandma's" old home remedies that might work? I love my Dad and want to see him get well..

Thanks in advance girls...I appreciate all advise.

Hugs
Brenda
