I posted an answer to your question yesterday, but appearantly it didn't get through.
You may take a look at pages 110-112 of The Amazing Liver Cleanse and see if this is what you have been looking for.
Also Chanca Piedra extract, 20 drops in a glass of water three times per day, is a good natural, product to reduce the size of calcified gallstones, which would make it easier for them to be flushed out during liver flushes. It is good to take it for 6 weeks at a time and then wait for one week and continue another six weeks. This is a good source: http://www.ashaninka.com/sales/chpiedra.html.
