I haven't seen this discussed in a while, so I thought I'd revive it
in case there is any new info out there (and because it's really been
affecting me lately). After drinking several infusions of Silver
Needle (Yin Zhen), I got a headache and some sinus pressure. This
pressure is similar to how I feel after drinking alcohol, so I assumed
it was due to dilated blood vessels and nasal/sinus tissues. Yesterday
I drank several infusions of Jade Flower (tea ball from Tao of Tea
that has a wonderful flavor, not just the novelty of the tea ball) and
got the same thing, including a headache near my temples which pretty
much ruined the rest of my day. I haven't noticed this with black
(fully oxidized) teas, and am in fact drinking several cups today to
verify this.

I don't know much about the chemistry of tea, but I presume these
headaches are caused by some component of tea which is chemically
altered or destroyed during oxidation.

Thanks!

Alan

P.S. I don't think it's the caffeine. I drink caffeinated soda all
day, and even take a 200 mg caffeine pill if I really need to stay
awake (no headache, just wide awake and a little jittery).

epigallocatechin gallate - ECGC in green teas is relatively high. Some
French studies have linked these components to asthma-like symptoms.
In some patients these levels have been know to induce a histamine
release.
There are studies being done in Japan and France regarding histamine
release in some patients following green tea consumption.
It could also be that the methods used to grow your tea may be
contaminated with allergenic sources, such as pesticides, herbicides
or fertilizers.
I would suggest trying these teas organically grown.
Be well.

You know that's really really interesting Shen, thank you. I thought it was
my imagination that I was feeling like I was having a little bit of a nasal
allergic reaction (sneezy) when I drank certain green teas (Huang Shan Mao
Feng and other "fluffy" types...could partially be tea dust too I suppose).
I am very sensitive to grass pollen, FWIW...interesting.

Funny you should mention grass, because I purchased a premium brand of green
tea a while back that tasted like grass. It was plain old green tea in
fancy sealed pouches and it tasted like grass. I've tried lots of other
brands and they always tasted like tea, but this brand's green tea tasted
like grass while its green/white blend tasted normal. Is it possible that
batches of tea on the world market are adulterated with grass? I've seen
bags of fake marijuana buds made from grass clippings, so why wouldn't some
Chinese tea traders mix in a percentage of grass with tea leaves just like
other traders adulterate flour with melamine or toothpaste with antifreeze?

Well, primarily in most cases with Chinese tea and decent Indian teas,
you can see the leaf or part of the leaf.
For those of us who take this tea stuff probably much too seriously,
myself included, we look at the leaves. We check out the leaves before
and after steeping. So, frankly, it would be pretty difficult to slip
grass in there.
In Japanese teas, it would also be difficult since colour in a factor
and cut of the leaf.

For one thing, nobody that I know condones actually DRINKING tea
balls; otherwise known as "art tea" or "tea art". It is not natural
and they use all kinds of different plastics and coloring agents to
make the teas appear so nice.

I don't want to bring the "pollution/dirty tea" thread into this, but
you could be suffering the effects of dirty tea. Perhaps some dormant
allergy has resurfaced in rection to some kind of preservative used in
the tea's making.

I sometimes really miss the days of ordering tea on the net and not
seeing this stuff with my own eyes....really.

Perhaps I'm using the wrong terminology for this:
http://www.taooftea.com/detail.php3?...aH AzP2lkPQ==

Tea anemone? Artisan tea? Tea ball? In any case, this is not one of
those tea balls with the flowers and the string and the cascase of
osmanthus blossoms.

Thanks for the suggestion. I first noticed this with Yin Zhen, which
is one of the least processed types of teas, so I'm either suffering
the same effect for two different reasons, or there is something in
white and green teas which is not present at the same levels in black/
red or even oolongs.

I plan on conducting an experiment and taking an antihistamine before
drinking the Yin Zhen again. I'll let you know what happens. It was
interesting to see so many articles on how EGCG has anti-allergy
properties when it might be causing my allergic reaction!

Alan

Alan,

I'm guessing this is related to "the nature of tea" in terms of
Chinese herb medicine.
In Chinese herb medicine, everything has a nature of "cold" or "warm",
from all herbs, foods, to your body.
White tea and green tea is more "cold in nature", oolong and black tea
is more "warm in nature".
This is related to the level of oxidizations.
If your body is also "cold in nature", when you drink teas which are
"cold in nature" as well, most of time it may upset your stomach or
other part of your body.
I'm not sure if your headache comes from the same reason, if you have
some Chinese Medicine Doctor in your town, you may want to ask him/her
about it.
But if you really don't feel well, maybe you should go for oolong and
black tea, it is not good for your body if you keep on experiencing
it.. Or at least, you should always eat something with your tea,
especially for green tea.
