Well it doesn't really bring stuff up
from the chest but there is a product on the market OTC now called Mucinex I use it and it helpes with thinning all the mucus both up
per and in your chest. You do have do yuk it up
and cough hard
to get the junk out get right over the sink head down and you will have better luck coughing
it out. I use the MucinexDM which helps calm the coughing
at night. Good luck and give it a try.
