The only thing that I have heard (up until now, of course), is the
flouride levels in tea. This is because of pollution, apparently, and the
tea plant is very good at soaking up minerals, so the flouride accumulates
in the tea plant. This would not affects buds, and fresh growth as much as
the stems or twigs (as in kukicha twig tea), and the large leaves that are
not fresh spring growth (large leaf puerh). There was one study that found
that puerh didn't have anywhere near as much flouride as did what the
study called "brick tea", which is apparently a much lower-grade tea that
contained many stems and twigs and things like that. Often used in Tibet
to make yak butter tea.

There's really no way to know other than to go in and do the measurements
yourself, probably. Do tea farms at higher altitudes have less pollution?
Good question. Are the flouride levels increasing year by year as the
pollution situation gets worse? That was the feeling I got. Does the water
which is being used to irrigate the tea bushes affect the flouride levels?
Probably. I have seen advertisements that many remote area tea farms/trees
are not irrigated, but simply rely on rain water. Would these types of
teas be safer? It would seem to me that they might be. I definitely try to
purchase pu-erhs made from a lower grade leaf (smaller leaves) - yes, they
don't age as well, but I would seriously doubt something like a 7542
(grade 4) would have much flouride. Getting up to grade 7, 8, 9, or off
the scale, as some puerhs are, I might tend to avoid those. Until I hear
otherwise, that is. I fully realize I could be wrong and might simply be
being paranoid.

So - misty mountain top remote area fresh growth buds - if you want to be
really safe from flouride problems, I guess. Avoid teas made from larger
old-growth leaves, I guess. Or maybe not? There's just really no way to
know unless you do the testing yourself. And, unlike caffeine, flouride
continues to be released from the tea leaves for up to 45 minutes of
soaking or more (way after the flavor is gone). So you can't rinse it out.
It's really quite a shame, actually. Depending on how much you drink, it
can be really bad for you.

On another note, I have ordered rather high-quality old-style
charcoal-roasted wuyi oolongs, and I do notice that I get a sort of
unpleasant feeling in my stomach from them. Maybe it's just me, but I do
have a fairly hard time with wuyi oolongs. They definitely throw me off
balance in an unpleasant way. Unfortunate, really. Green tea from Wuyi,
OTOH, I find to be very, very pleasant and wonderful, and tend to drink a
fair amount of it. So I don't doubt that there is something about the
charcoal. It's also supposed to be environmentally unfriendly. But I do
have a lot of respect for Wuyi Oolongs, so I keep trying.

This does raise some questions for me - are they being adulterated? It
wouldn't surprise me, I suppose. I think perhaps we just need to approach
it with an open mind, and listen to our bodies, listen to what they tell
us. I've never had an adverse reaction to pu-erh, but I definitely feel an
unpleasant sensation in my stomach sometimes after drinking the Wuyi
oolongs (not the Wuyi greens). So, that bums me out a little bit, but
OTOH, there are so many wonderful teas out there, there isn't really
anything to be depressed about.

Cheers to all, and may be learn more about these types of things with an
open mind!

It's just spooky to think that stuff that is supposed to be "good for
us" is actually causing us harm. These days, I ONLY drink green teas
that I know for a fact come from a place with little pollution, some
high quality new pu'er that i liked so much (and everyone thought it
was awesome quality) that I bought 56 cakes of it, and some Taiwan
Wulong that is bought from some of my close, personal friends of mine
in the tea business. I am just more than a little bothered about all
of this.

There was actually a period of time that I had a sharp pain in my
stomach after eating. I could not figure out what could possibly be
the cause; no previous medical history, was eating clean food at the
time, and I was in pretty good shape. I then realized that the
heavenly tasting tea that I had been drinking could have possibly been
the problem. I stopped drinking tea for a week, and my pain cleared
up. That's enough proof for me.

You know, when I started this thread, I thought I was going to get a
lot of negative backlash from the folks that didn't want to think that
it could be true. I am a little happy to hear that you see what I'm
saying and put stock in it. But, I am unhappy that others have had
the displeasure to see this information.

Ironically, there was more information on this exact type of thing
that was on sohu.com/sina.com/21cn.com; China's big online News
portals. To be brief, they did a study in the 3rd quarter of 2006
about some teashops around Guangzhou; some in Fangcun/Panyu/Liwang/
etc. It doesn't really matter where the sample was taken because
everyone in GZ will have to get their teas from Fangcun tea market or
have some contact with their teas. For everyone in Southern China,
there is NO CHOICE. Unless you know exactly where your tea comes
from, you will be drinking this tea.

Of the teas studied, they found traces of lead in some Longjing and
some chemical in the TieGuanYin called Methamidophos which is a
chemical found in some pretty serious pesticides. The levels of these
chemicals in the teas are simply too high for human exposure,
supposedly. If you are also interested, it also talks about some fake
Chinese rice wines that can cause blindness. Sorry, the site is in
Chinese.

http://news.sohu.com/20070125/n247821782.shtml

So, in short. I don't drink teas unless they come from a private
channel so that the tea can be traced back to where it was grown and
produced. I do not buy from wholesale markets anymore, and will only
do business with people that can assure me that their tea is clean by
scientific proof.

Just a note to all (and you all are so computer savy - you probably
are aware of this already) : if you download the google toolbar, there
is an "translate" option. This will translate the entire page (it
seems to do quite a good job) or word by word. I use it often and it
has really increased by uderstanding of language and slang venacular.

I haven't installed the Google toolbar, but I have used the Google
Chinese-English translation site (http://translate.google.com), and
I'm mostly frustrated by its opaque English and its disregard for
context in selecting which of a character's possible meanings to use.
Does the toolbar actually use a different translator?

Gosh, I really don't know.
I did notice that some pages are translated better than others and
that occasionally, the translations are "slited", awkward. It's been
handy, though.
I use "babelcarp" whenever I can. But, this has worked for me when
perusing Chinese tea shop sites.

Let me pose the question in a different way. Please go to the
translator in the Google toolbar and ask it to translate this page:

http://news.sohu.com/20070125/n247821782.shtml

What URL do you see then?

Default Cancer causing teas.

Lew,

I've always wondered why Google couldn't do better. I'm starting to
learn some Chinese grammar and I can see the problem with
constructions like aspect markers, measure words and topics. I
wished Google would give a literal pinyin translation which makes it
easier to see the grammar. I've picked up some college Chinese
grammar books but assumes you know the basics which I don't.
Fortunately I found a couple of good books at the Library no longer in
print which explain the basics. As one preface explained which I
paraphrase People think Chinese grammar is easy to learn because there
is no grammar like the West but the Chinese assume more by saying less
which is really the grammatical learning curve in Chinese.

I understand what you're saying: that would be useful for people like
us. I admit that I actually have a tool like that, though I'm not
releasing it publicly because it's kind of ragged and also because I
pay for the bandwidth. But I think Google rightly is more interested
in the far more numerous people who want a real translator.

The text I'm using, which is in print, is _Integrated Chinese_,
principal authors Yao and Liu. I'm happy with it, but I have nothing
to compare it with.

Interesting...I tried a bagged ooling from a local asian store and it made
my stomache really sick. I immediately threw the whole box out because I
knew something was up with it. It was very smokey tasting...in a way that I
really didn't like. I had terrible paid afterwards.
