Being a material Science engineer, I believe that the oil disolves the grease in the liver while it is being processed. And then expelled. Most all oils will disolve grease. We then accumulate grease in the liver from other parts of the body being processed in the liver and then another flush is required.
My cholestrol test results have decreased after 8 flushes, but I have many more to go. As I too was a non beliver when reading this website a couple years ago. I started again 9/04 and started flusing in nov.
Good luck and read alot and decide what YOU need to do.
