It would be a really good experiment to follow the Gerson protocol for a period of time and then do a Liver Flush just to see if the biliary system is de-clogged.
By the way quite a few of the post are from people who need support with their healing regime. That is why this is called a support forum and why there is predominantly minor problems being discussed.
My opinion is that any protocol that advocates castor oil is moving away from the natural healing concept because the castor bean is a toxic plant that cannot be eaten raw as a whole food. The poison in the bean is more potent that rattlesnake venom and there are conflicting views, whether the "pure" oil contains minute particles of the poison or not. I think castor oil is best use on the skin as a pack because the action of it when ingested is one of a laxative and emetic not a nutrient.
