I would add that if cassia fistula should absolutely be avoided, we better tell the monkeys and perhaps apes as well. When I was in Sri Lanka, I asked if there’s cassia fistula in the country. The answer was: it’s the monkeys who eat that!
I already consume anthraquinone via senna, so I'm still leaning towards thinking that it's OK to take occasionally for short periods. It's longer term chronic use that I'm particularly evaluating, though the fact that it has apparently been banned in Germany does give me pause about even occasional use. Anyone know why they banned it?
How long is cassia fistula in season for the Toque Macaques and Leaf Monkeys to eat it? I suspect that it's not year-round. Do they all eat it as a staple food or do only some of them eat it when they have constipation, as you are suggesting humans should use it? If the monkeys all eat it daily like a staple food instead of a medicinal when it's available, doesn't that give the non-constipated monkeys overly loose bowels or even diarrhea and threaten mineral and nutritional deficiencies as a result?
The monkey info is interesting, but just as I don't think that a food is guaranteed as beneficial staple food for me just because cave men ate it during the Stone Age, so I also don't think that it is guaranteed as a beneficial staple food if monkeys eat it. I doubt that monkeys are enormously more intelligent than Stone Agers were and therefore I do not think that monkeys are guaranteed to be free from making imperfect choices.
No one has yet addressed the problem that I've never even seen cassia fistula in person, so it doesn't appear to be a practical solution where I live, regardless of how safe it is. When it comes to anthraquinone, senna is the much more common vehicle in New England. I never even saw cassia fistula sold in Florida, despite the fact that it can be grown there.
I remember that GCB told us to begin carefully with cassia
So even GCB is cautious with cassia fistula and apparently recognizes it is not perfectly benign?

"Fortunately, most of us are not monkeys any longer."
Christopher Ryan & Cacilda Jethá assert that we are apes (thanks to GS for the info about these authors)
Hanna didn't say that we aren't apes, she said we are not monkeys (which is true) and our dietary needs are therefore not necessarily the same--and I would add that we never were monkeys, as they are not in our ancestral lineage--they are a separate branch. Craig B. Stanford, Professor of Anthropology and Biological Sciences at USC and Director of the USC Jane Goodall Research Center, calls us "the hunting apes" (
http://www.amazon.com/Hunting-Apes-Eating-Origins-Behavior/dp/0691088888). No scientist claims that humans are descended from monkeys or chimps or gorillas, and with the discovery of a 6-7 year old Sahelanthropus tchadensis fossil that some scientists believe is a bipedal hominid that predates monkeys, monkeys are now considered by some scientists to be descended from hominids, rather than monkeys and hominids being descended from some other type of ancestor. So by your logic of emulation, perhaps monkeys should emulate our ancestral hominid diet rather than we emulate a monkey diet.
Plus, chimpanzees, bonobos, gorillas, and orangutans have different diets, so the fact that we are apes doesn't mean that we should necessarily eat exactly like any one of the other ape species, as they don't even eat the same things themselves. Plus, the more relevant comparison would be to our closer relatives--other species of the genus Homo (H. sapiens Idaltu, H. rudolfensis, H. rhodesiensis, H. neanderthalensis, etc.)--especially those within our own lineage and environs. Heck, even among us humans we have different individual needs.
Also, I don't see why cassia fistula should be such a big deal, as it was not a staple food for the first 2.5 million years of history of the genus Homo, unless one is mainly interested in defending GCB's "natural nutrition" hypothesis.
