Are there any other explanations why the liver flush works?

Hello everyone,
First off, I should say that I've done several Liver Flushes and they've all brought me tremendous short term relief. I have not completed enough flushes to know whether or not the results will ever become more or less permanent; I'm hoping that they eventually will. In the short term, for a day or two, I have a tremendous amount of good energy and crystal clear lucidity, my brain functions much, much better than usual. I know for a fact that Liver Flushes work well for me, however, I just got through reading an older post in this forum by Hveragerthi that I found quite convincing. The post basically said that the materials passed during flushes have been analyzed and found to not be gallstones, and there were numerous links and examples to support this. So, in other words, I'm a firm believer in the phenomenon but I question the explanation. Does anyone know whether simply flushing out a large quantity of bile from one's system could account for all the apparent benefits? Does anyone else have any ideas about why this procedure works so wonderfully for so many people, if it's not actually releasing any gallstones?
