Herbal remedy blamed for high cancer rate in Taiwan

Postby TainanCowboy » 10 Apr 2012, 13:05

I have not looked up the Chinese name for this plant, nor have I looked at which TCMs contain it.
Maybe some other forum member could supply that info.
Its worth sharing this with locals who may be using a TCM that contains this plant.

Herbal remedy blamed for high cancer rate in Taiwan
(excert)
A toxic ingredient in a popular herbal remedy is linked to more than half of all cases of urinary tract cancer in Taiwan where use of traditional medicine is widespread, said a US study Monday.

Aristolochic acid (AA) is a potent human carcinogen that is found naturally in Aristolochia plants, an ingredient common in botanical Asian remedies for aiding weight loss, easing joint pain and improving stomach ailments.

The ancient herb has been touted around the world for thousands of years for everything from gout to childbirth, but scientists now know it carries serious risks of causing kidney disease and urinary cancers.

The latest research found it can interact with a person's DNA and form unique biomarkers of exposure, as well as creating signals within tumor suppressing genes that indicate the carcinogen has been ingested.

In Taiwan, where previous research has shown about one-third of the population has taken AA in recent years, rates of urinary tract and kidney cancer are about four times higher than in Western countries where use is less common, said the findings in the Proceedings of the National Academy of Sciences.

"It is a rare tumor and Taiwan has the highest incidence of any country in the world," said lead author Arthur Grollman of the department of pharmacological sciences at Stony Brook University in New York.

"The fact that Taiwan had the highest incidence both of cancer and this renal disease -- that was our clue that something was going on there," Grollman told AFP.

As it is, we seem to regard it as a positive objection to a reasoner that he has taken one side or the other. We regard it (in other words) as a positive objection to a reasoner that he has contrived to reach the object of his reasoning. We call a man a bigot or a slave of dogma because he is a thinker who has thought thoroughly and to a definite end.

Although exactly how exposure to aristolochic acid results in chronic renal damage remains uncertain, this does look serious.

Aristolochic acid nephropathy remains an underdiagnosed renal illness because of its lack of identification in certain parts of the world. It remains an international public-health problem that can be resolved only through implementation of measures to halt the risk of exposure to this toxic herb.



Those are both from the official journal of the International Society of Nephrology, not just the usual "some guy on TV" that we all too often get in Taiwan.

Feckin' 'ell! So the Chinese quacks are prescribing kidney failure potions and have been for thousands of years? That IS scary, indeed! :eek:
