I only found out that a Liver Flush existed by finding this website (now I'm hooked). Knowing that the ingredients wouldn't cause me any danger,I decided to do my first flush 2 weeks ago out of curiousity to see what would happen. I am a 36 year old and thought only elderly people had stones. Boy did I get a surprise to find green stones (coated in white fat) and lots of them too. Some stones were the size of walnuts. They weren't hard like stones either, soft almost like a cheese texture (sounds gross I know) but exciting to think that you no longer have that rubbish blocking up your system. If you decide to flush and inspect your stones, make sure your wear disposable gloves, the smell of the stones doesn't wash off your hands easily, as I discovered after washing my stones!!! All the best, let us know how you get on.
