I agree, it would be worth trying the MC. In the book he says that The Master Cleanser cleans out mucous, waste and disease. I think that is the answer right there. But if you have any doubts, check with your doctor. I think it is totally worth a shot. I don't have a mucous problem per se but have been getting rid of quite a bit of mucous through my nose on this cleanse. and it is not clear mucous! Good luck to you, you have nothing to loose!! (except mucous, ha ha) go for it!! :>
