I have a problem with thick phlegm and have to clear my throat.
Papaya juice has been shown to work but it was so expensive for the juice.
Now I drinks Motts Natural pressed apple juice. It is a dark juice with bits of pulp in it. Something in it really helps to thin the thickness and I don't get choked or have to clear my throat a lot anymore.
When I have a cold or extra phelm and it gets bad, I take papaya enzyme from GNC as directed on the bottle for maximum dosage.
I had a rented cough assist machine, but it never really seemed to help with the thick clog in my throat. I sent it back because these things work well for me.
