re: COPD & Lung Cancer and virgin coconut oil -- I found almost immediate relief from thick mucous taking VCO. I started out with 1 T. with each meal, sometimes in tea or room temp juice. It thins the mucous making it easy to cough up. I also drink 2 quarts of water in addition to the VCO. The water alone did not help. My nasal passages are both open for the first time in years and breathing is much easier. VCO makes the skin lovely.
