I have never used Gold Coin Grass or any other herb when liver flushing. I had an extremely congested liver and occasional acute gallbladder attacks when my Naturopath introduced me to Liver Flushing just over three years ago. I have released around 6000 stones with nothing more than apple juice, Epsom salt, olive oil, and grapefruit or lemon juice. I passed over 5500 stones before having some stone free flushes. The other 500 or so stones have come out in my maintanence flushes done every three months or so as needed.
