I know this is an old topic, but I feel I should make some comments. I have done 14 liver/gallbladder flushes.

1. Every flush is different. Some flushes produce hundreds of green and/or beige stones, while some flushes produce nothing. If the stones are formed from olive oil and you ingest the same amount of oil each time, one would expect roughly the same results.
2. Parasites (specifically, liver flukes) were mixed in with the stones during my first seven flushes. There are many pictures of liver flukes, both from humans and animals, on the Internet, and so there can be no doubt as to what I expelled.
3. While these stones are sitting in the colon, waiting to be released into the toilet, you are weak and lethargic and even sickly. But as soon as they are flushed with a colonic or an enema, you feel 100% better. This tells me that the stones are highly toxic and are not simply olive oil. If you cut a stone open, you will often find a foul-smelling greenish black liquid or semi-liquid.
4. If you dye the oil/lemon juice mixture with charcoal or food coloring, you get the same green and/or beige stones.
5. You always feel better - more energized - two days after the flush. The more flushes that you do, the more your health seems to improve. Remember the old adage: "You can't argue with success."
6. The stones that "melt in the sun" are from the liver. They are mostly cholesterol. That is why they melt. The hard calcified stones come from the gallbladder. The latter can be seen via ultrasound. The former can not.

As for Hulda Clark, she was persecuted for getting people well, like Harry Hoxsey (such a very sad story), Stanislaw Burzynski, Rene Caisse (from Canada) and Max Gerson, to name a few. As soon as you become a threat to the pharmaceutical evil-empire, which is protected by the government, you are either shut down, or imprisoned, or forced to leave the country. That's why there are so many cancer clinics in Mexico. They can legally do there what is forbidden in the U.S. - and they are actually getting people well. But you will never hear that from the U.S. media.
