And there is a big one - every culture had some kind of fermented drink, ie. alcohol! which is indeed a chemical poison. And, there were quite a few other recreational chemicals in ancient times as well. I don't know about China, but many other Asian cultures do have raw foods on the menu.

Quite interesting,

I would have singled out meat as the most likely to induce parasitic infestation. It starts decomposing right after killed, then injected chemical preservatives -antibiotics, hormones-, then heavily irradiated. Consider the synthetic stuff that makes up livestock feed, or the number of sick animals in there and their rotting environment. Eighty percent of herbicides used in the U.S. are sprayed on corn and soy beans which are used for cattle feed. Vegetarians show much lower cancer rates than meat-eaters.
As for Moritz, he's said his one-a-year maintenance flushes haven't produced any more stones, which he credits to diet and lifestyle.

While he concurs with the liver forming stones to trap noxious substances, he also stresses that chemicals like fluoride or medicines cause stones because they alter the composition of bile, depleting its bile salts and making it congeal into hard structures. He says: "I repeatedly observed that people who have taken medicines in the past have had considerable more gallstones than those who took none."

Clark's theory that without a parasite cleanse the stones won't come out is much debatable.
Moritz outlines the basic differences of their two protocols thus:

"Dr. Clark's liver cleanse does not involve softening of stones before the flush, which makes it easier for the stones to pass. Harder stones are much more resistant than those softened with apple juice or malic acid, and special herbs, if need be. She also does not advocate cleansing of the colon before and after the the flush, which by itself can prevent successful cleansing and cause potentially harmful side-effects (inflammation, infection, toxic blood, skin problems, etc.). She says, though, that without parasite cleansing prior to the liver flush, you won't get out stones. This, however, applies to mostly those who don't take the above measures."

He also dismisses the Master Cleanse due to its phosphoric acid content, this scenario can be somehow equated to the 3-day megadose :

"You may have heard that I am not a proponent of the Master Cleanse, at least not for everybody. For Pitta types the phosphoric acid and other acids in citrus fruit can cause major bowel disruptions, especially when the intestinal tract has already become cleaner through previous cleansing.
Only the typical Vata type can tolerate that much sour taste without suffering such side-effects.

I would certainly discontinue with the MC, otherwise you may erode your mineral composition of the your gastro-intestinal tract. You are not the only one who has had this kind of problem."

One more quote responding to someone suffering extreme itching, though this might be getting a bit redundant by now:
" But, your symptoms indicate toxicity in the connective tissue under the skin, and perphaps also in the blood. If you followed Hulda Clark's cleansing regimen, you haven't done the pre-treatment for softening the stones and the essential colonics before and after the liver flushes. Trapped stones in the colon can cause extreme toxemia and such symptoms as you experience. "

Finally, for those of you knowledgeable with Chinese medicine, what do you make of Julia Chang's assertion (from her website sensiblehealth.com) that "Chinese medicine understands a lot of things, but it doesn't understand hormones at all." ? Her contention is that many times the things prescribed by Chinese practitioners will end up aggravating hormone-related conditions, as happened in her own case.

Isn't it interesting that according to the Curezone poll, only 1% of people regret having started flushing?
