If you use orthophosphoric acid make sure that you rinse your mouth out well each time after taking it. The acid can etch tooth enamel if any remains in the mouth for an extended period of time.

The apple juice method I did was:
Every day for a week leading up to the flush, juice a litre of organic apples. Add a TBSPN of olive oil. Drink 4 x 250ml during the day. Then on the 7th day, do your grapefruit juice/olive oil (1 cup each) drink just before bed. (I didn't do Epsom Salts then, it was just as effective). The stones were not bright green and shiny, this is going back a few years so I can't describe them well but I do remember being surprised at how different they were to the first two times I had flushed. Like acid had started breaking them down - kind of paler and more porous.

I think there is an outline of a similar apple juice flush on the Liver Flush homepage.

Thanks for your reply Susie! Another option for later if the herbs aren't effective. Can't vouch for it yet though.

I was so blocked up with stones that bile wasn't passing and my stools were clay-coloured. A naturopath I went to put me on a product called DTM made by "Macromolecular" an Australian supplement company. The next day I had brown stools for the first time in days (sorry to be graphic!).

The biggest effect I noticed was that my skin became very soft and supple. DTM has lecithin and various aminos for the liver/GB like L-cysteine.

Now I am taking a locally made product called Liverol. It's basically the same but has a few more ingredients like Dandelion and Folic acid.

Macromolecular say that if you take DTM for a year, you should have no more problems. My friend (a naturopath in WA) put one of her clients on it. She was going into hospital with GB attacks almost every second weekend. Her attacks subsided and she was really happy but my friend hasn't followed up on it yet to see if she's still OK.

So, I don't know if it works like they say. But I am staying on the Liverol for a year to see!

I am interested in Chinese herbs though, but I guess you have to give one method a fair go before trying another! Keep in touch!
