I did a Liver Flush on the last day of a 12day Master-Cleanse and it went just fine (don't know how it would turn out if you continued with the Master-Cleanse but I think it would be fine, although I wouldn't take the laxative on the same night as the liver flush, just do the SWF (Salt-Water-Flush) the next morning). The apple juice is to soften up the stones. You can take malic acid capsules instead or gold coin grass, although I've read of a few people who don't even bother to take anything prior to the flush.

Me personally, I kind of like ending a Master-Cleanse with a liver flush, since I'm already starving myself. I never use Epsom Salts - it makes me want to throw up just thinking about it. What I do is take malic acid capsules for a few days prior to the flush, then, on the night of the flush, I do a salt water enema(2qt bag) to clear the path for the stones. I mix 1/2C olive oil w/ 3/4C fresh squeezed ruby red grapefruit juice, drink it down with a straw shoved to the back of my throat (really don't like that taste staying in my mouth), then lie down with my head propped up a little. I've read that you should lie on one side or the other, and have also read that it doesn't really matter, so take your pick : ) Next day, I either do a SWF (Salt-Water-Flush) or another enema. You will be passing stones for several days afterwards, so it is helpful to keep doing SWF (Salt-Water-Flush) or enemas (I prefer enemas) for a few days afterward.
