Hi, NAC (enzyme) will liquefy and relieve congestion after taking 4 pills a day… It healed me very quickly not all the way though. The antifungal drug helped a lot. Also, I had Chinese herbs made for me specifically with formula I requested that I accidently found and tried and it cleared me from all kinds of things, colon, ears, sinuses. Final suggestion google Fire Cider Cold and Flu Remedy, by Rosemary GladstarHide, it does wonders to me.
