My friend Andreas Moritz has written, "The Amazing Liver Cleanse." (AMAZON).

I was not feeling well and my closest friend's wife had just died of pancreatic cancer in 2000. My friend asked if I would go to Mexico after his wife died to take a break. I was told by a psychic friend that on my trip I would meet two very metaphysically like minded people. Low and behold they were staying in my friends bed and breakfast. It was Andreas and his girlfriend Lily. Andreas told me about the liver cleanse and said I was not sick but my liver was congested.
I performed 8 Liver Cleanses over the next 7 months.
The shift that occurred in my physical health was dramatic.
Blood pressure dropped, cholesterol dropped, weight dropped and energy soared.
As for the people who wrote in this article that the olive oil creates the stones I would have to say obviously they have not done a cleanse. They would need to explain how in the first 2 cleanses I passed thousands of stones the size of frozen peas.
As I progressed to the 3rd and 4th cleanse I passed some stones the size of my thumb nail. The fifth cleanse was the most remarkable as I passed two large masses of clumped stones each the size of my thumb. The sixth cleanse there were hardly any stones and the seventh and eighth almost nothing. It was here that I began to see the medical changes in my blood pressure 135/88 to 112/70, cholesterol 230 to 190, and weight 218 to 205 and the increase in energy.

Since 2000 I have done the cleanses every six months, March and Sept.
Occasionally now I get a few of the pea sized stones.
I am a practicing dentist 25 years. I have talked to numerous of my physician friends
about the cleanse and they chuckle at me and this supposedly old wives tail as they continue to write prescription drugs for their patients. I look at their bloated bellies and feel the frustration of having found this simple and remarkable healing process and see their inability to notice here is something that is not only inexpensive and simple to do but has predictable and remarkable results.
