I am coincidentally trying to develop a green tea for my company Mean Co. Inc.

meancosmalltalk I have a tea that is listed as a

noxious weed in Arizona but it seems mild mannered and nice to me. It is a green

tea when the leaves are young and turns to a brownish red when the leaves

mature. I would be glad to send along some seeds if you let me know your

address. As far as its qualities I would not venture an opinion just yet. Tea

may make people react in different ways. Just as some people are allergic to

some foods. My tea is mellow and may contain some tannin. I have never had it

analyzed. There are alot of different green teas. Marijuana for instance can be

brewed as tea for a soothing effect. Young immature leaves are best for this I

think. My tea is not marijuana however.

I don't think that " green tea " is referring to any herb that is green that can

be brewed as tea. Green tea is caffienated and is a special plant (or plants

Thanks, there was some good stuff in there. I have already searched all the

published papers on green tea- and very impressive they are too! I started

drinking it as an anti-oxident, to lower post-prandial insulin (and

therefore resulting symptoms) and it seems to work a treat for that, I

really feel the benefit. It slows both the digestion of starch and the

absoprtion of glucose, so is ideal for insulin resistance, especially as it

reduces the blood fats that result (phlegm/damp?). It must have some Liver

properties too - I was interested to see how they translate.

 

I was thinking of using it as an antioxident for the horse, but

unfortunately slowing digestion/absorption of starches and sugars means more

gets into the hindgut undgested, where it could cause trouble - in horses.

Thanks, but it is the specific tea with all the positive research I am

after!

[Guest guest]

the tea is from the plant named camelia sinensis

there is different kind of this plant, and many methods to prepare the fresh

leaves. what we call green tea is the dry non prepare leaves. oolong tea is semi

fermented leaves. Black tea is fermented leaves. This is a very very short

explanation. For each type, you have many kinds of quality and proprieties.

There is many web sites, many books where you can find good informations about

teas.

The terms " green " and " black " refers to the processing. It's the

same plant, but different processing methods.

 

When tea leaves are picked, certain chemical reactions start to

occur. These processes are halted by steaming the leaves. This is

green tea. In black tea, the processes are allowed to proceed.

 

As a result, green and black teas have different properties.

[Guest guest]

I understand that the green, black, oolong and white teas would have

different properties, but could someone here explain what they are?

 

Thanks,

Sarah,

I know that Green Tea has many soothing qualities. Actually, it is

in a complex I take for improving joint flexibility with

Glucosamine, Bromelain and some fructose for maximum

absorption. So I'm inclined to think that it, combined with these

other things acts as a booster. Not sure. Just know that it works!

I was starting to get premature arthritis in my finger joints. All

gone! Beyond that, I'm not sure what it's particular scientifically

researched attributes are. Hope you'll post when you find out

more.

Effect of green tea catechins on plasma cholesterol level in cholesterol-fed

rats.

 

Muramatsu K, Fukuyo M, Hara Y.

 

Effects of tea catechins (tannins) on lipid metabolism were studied in male

weanling rats fed a 25% casein diet containing 15% lard and 1% cholesterol

for 28 days. Crude tea catechins prepared from green tea powder were

supplemented at a 1% and 2% of the lard-cholesterol diet. The addition of 2%

tea catechins slightly depressed growth but at the 1% level was without

effect. Tea catechins decreased plasma total cholesterol, cholesterol ester,

total cholesterol--HDL-cholesterol (VIDL-+LDL-cholesterol) and atherogenic

index (VLDL-+LDL-cholesterol/HDL-cholesterol). Hematocrit and plasma glucose

were not altered by the addition of tea catechins. The liver weight, liver

total lipids and cholesterol concentrations in rats fed the lard-cholesterol

diet increased more than in the control rats, but the addition of tea

catechins to the lard-cholesterol diet decreased those parameters. Tea

catechin supplementation increased fecal excretion of total lipids and

cholesterol. The results demonstrate that tea catechins exert a

hypocholesterolemic effect in cholesterol-fed rats.

Green tea polyphenols inhibit the sodium-dependent glucose transporter of

intestinal epithelial cells by a competitive mechanism.

Shimizu M.

 

Department of Applied Biological Chemistry, Graduate School of Agricultural

and Life Sciences, The University of Tokyo, 1-1-1 Yayoi, Bunkyo-ku, Tokyo

113-8657, Japan.

 

Intestinal glucose uptake is mainly performed by the sodium-dependent

glucose transporter, SGLT1. The transport activity of SGLT1 was markedly

inhibited by green tea polyphenols, this inhibitory activity being most

pronounced in polyphenols having galloyl residues such as epicatechin

gallate (ECg) and epigallocatechin gallate (EGCg). Experiments using

brush-border membrane vesicles obtained from the rabbit small intestine

demonstrated that ECg inhibited SGLT1 in a competitive manner, although ECg

itself was not transported via SGLT1. The present results suggest that tea

polyphenols such as ECg interact with SGLT1 as antagonist-like molecules,

possibly playing a role in controlling the dietary glucose uptake in the

intestinal tract.

Regulation of intestinal glucose transport by tea catechins.

 

Shimizu M, Kobayashi Y, Suzuki M, Satsu H, Miyamoto Y.

 

Department of Applied Biological Chemistry, The University of Tokyo, Japan.

 

Intestinal glucose uptake is mainly performed by its specific transporters,

such as SGLT 1, GLUT 2 and 5 expressed in the intestinal epithelial cells.

By using human intestinal epithelial Caco-2 cells we observed that

intestinal glucose uptake was markedly inhibited by tea extracts. While

several substances in green tea seem to be involved in this inhibition,

catechins play the major role and epicatechin gallate (ECg) showed the

highest inhibitory activity. Since our Caco-2 cells did not express enough

amount of SGLT 1, the most abundant intestinal glucose transporter, the

effect of ECg on SGLT 1 was evaluated by using brush border membrane

vesicles obtained from the rabbit small intestine. ECg inhibited SGLT 1 in a

competitive manner, although ECg itself was not transported via the glucose

transporters. These results suggest that tea catechins could play a role in

controlling the dietary glucose uptake at the intestinal tract and possibly

contribute to blood glucose homeostasis.

Comparison of the antioxidant content of fruits, vegetables and teas

measured as vitamin C equivalents.

 

du Toit R, Volsteedt Y, Apostolides Z.

 

Department of Biochemistry, University of Pretoria, Pretoria 0002, South

Africa.

 

Most of the health benefits of black, green and oolong teas made from

Camellia sinensis are attributed to their antioxidant content. Many plants

and spices have been used to make infusions that are erroneously referred to

as 'teas'. The term 'rich in antioxidants' is often used to describe such

infusions, often without scientific support. We have used the DPPH method to

quantify the total radical scavenging capacity (RSC) of a wide range of

'teas', fruits and vegetables. The results are presented as vitamin C

equivalents. These results are compared to the RSC of the recommended

portions of fruits and vegetables in the food guide pyramid for a healthy

and balanced diet. The EC(50) results show that there are no statistically

significant differences in the RSC of black, green and oolong teas. However,

the RSC of 'teas' made from other species of plants are significantly lower.

Our results show that one or two cups of tea would provide a similar amount

of RSC as five potions of fruits and vegetables or 400 mg vitamin C

equivalents. This would be comparable to two capsules (200 mg) of vitamin C.

Caution is advised in extrapolating these in vitro results to humans due to

bioavailability.

Powdered green tea has antilipogenic effect on Zucker rats fed a high-fat

diet.

 

Hasegawa N, Yamda N, Mori M.

 

Department of Food and Nutrition Nagoya Bunri College, Nagoya, Japan.

 

The effect of powdered green tea on the lipid metabolism was studied in male

Zucker rats fed a 50% sucrose diet containing 15% butter. The oral treatment

of 130 mg powdered green tea per day depressed body weight increase and

various adipose tissue weights but food intake was unaffected. The treatment

also slightly increased the plasma triglycerides. These effects were likely

mediated by the inhibition of lipogenesis in the adipose tissues. The

experimental group had a higher concentration of liver total lipid,

triglycerides and plasma protein, and lower liver weights than the controls.

This may be due to lipid deposition in the liver because of the reduction in

adipose tissue weights. It was found that powdered green tea lowered the

plasma total cholesterol but liver total cholesterol was unaffected. The

results indicate that the hypocholesterolemic activity of powdered green tea

might be due to the inhibition of the synthesis of cholesterol in the liver.

Tea enhances insulin activity.

 

Anderson RA, Polansky MM.

 

Nutrient Requirements and Functions Laboratory, Beltsville Human Nutrition

Research Center, U.S. Department of Agriculture, Beltsville, Maryland 20705,

USA.

 

The most widely known health benefits of tea relate to the polyphenols as

the principal active ingredients in protection against oxidative damage and

in antibacterial, antiviral, anticarcinogenic, and antimutagenic activities,

but polyphenols in tea may also increase insulin activity. The objective of

this study was to determine the insulin-enhancing properties of tea and its

components. Tea, as normally consumed, was shown to increase insulin

activity >15-fold in vitro in an epididymal fat cell assay. Black, green,

and oolong teas but not herbal teas, which are not teas in the traditional

sense because they do not contain leaves of Camellia senensis, were all

shown to increase insulin activity. High-performance liquid chromatography

fractionation of tea extracts utilizing a Waters SymmetryPrep C18 column

showed that the majority of the insulin-potentiating activity for green and

oolong teas was due to epigallocatechin gallate. For black tea, the activity

was present in several regions of the chromatogram corresponding to, in

addition to epigallocatechin gallate, tannins, theaflavins, and other

undefined compounds. Several known compounds found in tea were shown to

enhance insulin with the greatest activity due to epigallocatechin gallate

followed by epicatechin gallate, tannins, and theaflavins. Caffeine,

catechin, and epicatechin displayed insignificant insulin-enhancing

activities. Addition of lemon to the tea did not affect the

insulin-potentiating activity. Addition of 5 g of 2% milk per cup decreased

the insulin-potentiating activity one-third, and addition of 50 g of milk

per cup decreased the insulin-potentiating activity approximately 90%.

Nondairy creamers and soy milk also decreased the insulin-enhancing

activity. These data demonstrate that tea contains in vitro

insulin-enhancing activity and the predominant active ingredient is

epigallocatechin gallate.

Epigallocatechin gallate, a constituent of green tea, represses hepatic

glucose production.

 

Waltner-Law ME, Wang XL, Law BK, Hall RK, Nawano M, Granner DK.

 

Department of Molecular Physiology and Biophysics, Vanderbilt University

School of Medicine, Nashville, Tennessee 37232-0615, USA.

 

Herbs have been used for medicinal purposes, including the treatment of

diabetes, for centuries. Plants containing flavonoids are used to treat

diabetes in Indian medicine and the green tea flavonoid, epigallocatechin

gallate (EGCG), is reported to have glucose-lowering effects in animals. We

show here that the regulation of hepatic glucose production is decreased by

EGCG. Furthermore, like insulin, EGCG increases tyrosine phosphorylation of

the insulin receptor and insulin receptor substrate-1 (IRS-1), and it

reduces phosphoenolpyruvate carboxykinase gene expression in a

phosphoinositide 3-kinase-dependent manner. EGCG also mimics insulin by

increasing phosphoinositide 3-kinase, mitogen-activated protein kinase, and

p70(s6k) activity. EGCG differs from insulin, however, in that it affects

several insulin-activated kinases with slower kinetics. Furthermore, EGCG

regulates genes that encode gluconeogenic enzymes and protein-tyrosine

phosphorylation by modulating the redox state of the cell. These results

demonstrate that changes in the redox state may have beneficial effects for

the treatment of diabetes and suggest a potential role for EGCG, or

derivatives, as an antidiabetic agent.

To evaluate the possible effects on insulin function, 49 herb, spice, and

medicinal plant extracts were tested in the insulin-dependent utilization of

glucose using a rat epididymal adipocyte assay. Cinnamon was the most

bioactive product followed by witch hazel, green and black teas, allspice,

bay leaves, nutmeg, cloves, mushrooms, and brewer's yeast. The glucose

oxidation enhancing bioactivity was lost from cinnamon, tea, witch hazel,

cloves, bay leaf and allspice by poly(vinylpyrrolidone) (PVP) treatment,

indicating that the active phytochemicals are likely to be phenolic in

nature. The activity of sage, mushrooms, and brewers's yeast was not removed

by PVP. Some products such as Korean ginseng, flaxseed meal, and basil have

been reported to be effective antidiabetic agents; however, they were only

marginally active in our assay. Our technique measures direct stimulation of

cellular glucose metabolism, so it may be that the active phytochemicals in

these plants improve glucose metabolism via other mechanisms or that this in

vitro screening is not a reliable predictor of hypoglycemic effects in vivo

for some products. In summary, the positive effects of specific plant

extracts on insulin activity suggest a possible role of these plants in

improving glucose and insulin metabolism.

Modulation of endocrine systems and food intake by green tea

epigallocatechin gallate.

 

Kao YH, Hiipakka RA, Liao S.

 

Ben May Institute for Cancer Research, Department of Biochemistry and

Molecular Biology, and Tang Center for Herbal Medicine Research, University

of Chicago, Illinois 60637, USA.

 

Green tea polyphenols, especially the catechin, (-)-epigallocatechin gallate

(EGCG), have been proposed as a cancer chemopreventative based on a variety

of laboratory studies. For clear assessment of the possible physiological

effects of green tea consumption, we injected pure green tea catechins ip

into rats and studied their acute effects on endocrine systems. We found

that EGCG, but not related catechins, significantly reduced food intake;

body weight; blood levels of testosterone, estradiol, leptin, insulin,

insulin-like growth factor I, LH, glucose, cholesterol, and triglyceride; as

well as growth of the prostate, uterus, and ovary. Similar effects were

observed in lean and obese male Zucker rats, suggesting that the effect of

EGCG was independent of an intact leptin receptor. EGCG may interact

specifically with a component of a leptin-independent appetite control

pathway. Endocrine changes induced by parenteral administration of EGCG may

relate to the observed growth inhibition and regression of human prostate

and breast tumors in athymic mice treated with EGCG as well as play a role

in the mechanism by which EGCG inhibits cancer initiation and promotion in

various animal models of cancer.

Direct scavenging of nitric oxide and superoxide by green tea.

 

Nakagawa T, Yokozawa T.

 

Institute of Natural Medicine, Toyama Medical and Pharmaceutical University,

2630 Sugitani, Japan.

 

In the present study, we investigated the free radical scavenging effects of

green tea extract and green tea tannin mixture and its components using a

nitric oxide (NO) and superoxide (O(2)(-)) generating system in vitro. Green

tea extract showed direct scavenging activity against NO and O(2)(-) and

green tea tannin mixture, at the same concentration, showed high scavenging

activity. Comparison of the activities of seven pure compounds isolated from

green tea tannin mixture showed that (-)-epigallocatechin 3-O-gallate

(EGCg), (-)-gallocatechin 3-O-gallate (GCg) and (-)-epicatechin 3-O-gallate

(ECg) had higher scavenging activities than (-)-epigallocatechin (EGC),

(+)-gallocatechin (GC), (-)-epicatechin (EC) and (+)-catechin ©, showing

the importance of the structure of flavan-3-ol linked to gallic acid for

this activity. Among the gallate-free tannins, EGC and GC were more

effective O(2)(-) scavengers than EC and C, indicating the O-trihydroxy

structure in the B ring is an important determinant of such activity.

However, this structure did not affect the NO scavenging activity. These

findings confirm that green tea tannin has excellent antioxidant properties,

which may be involved in the beneficial effect of this compound.

M C S, K S, Kuttan R.

 

Amala Cancer Research Centre, Amala Nagar,Trichur 680 553, Kerala, India.

 

An aqueous solution of green tea polyphenols (GTP) was found to inhibit

lipid peroxidation (LP), scavenge hydroxyl and superoxide radicals in vitro.

Concentration needed for 50% inhibition of superoxide, hydroxyl and LP

radicals were 10, 52.5 and 136 micro g/ml, respectively. Administration of

GTP (500 mg/kg b.wt.) to normal rats increased glucose tolerance

significantly (P<0.005) at 60 min. GTP was also found to reduce serum

glucose level in alloxan diabetic rats significantly at a dose level of 100

mg/kg b.wt. Continued daily administration (15 days) of the extract 50, 100

mg/kg b.wt. produced 29 and 44% reduction in the elevated serum glucose

level produced by alloxan administration. Elevated hepatic and renal enzymes

produced by alloxan were found to be reduced (P<0.001) by GTP. The serum LP

levels which was increased by alloxan and was reduced by significantly

(P<0.001) by the administration of 100 mg/kg b.wt. of GTP. Decreased liver

glycogen, after alloxan administration showed a significant (P<0.001)

increase after GTP treatment. GTP treated group showed increased antioxidant

potential as seen from improvements in superoxide dismutase and glutathione

levels. However catalase, LP and glutathione peroxidase levels were

unchanged. These results indicate that alterations in the glucose utilizing

system and oxidation status in rats increased by alloxan were partially

reversed by the administration of the glutamate pyruvate transaminase.

exposed to vitamin C the triglyceride concentration was decreased (p < 0.05)

and the activity of glycerophosphate dehydrogenase, a marker of adipose

conversion, was significantly inhibited (p < 0.01). These data suggest that

green tea may have a lipolytic activity due to the mechanism by which the

A functional food product for the management of weight.

 

Bell SJ, Goodrick GK.

 

Functional Foods, Inc., Belmont, MA 02478, USA. staceyjbell

 

More than half of Americans have a body mass index of 25 kg/m2 or more,

which classifies them as overweight or obese. Overweight or obesity is

strongly associated with comorbidities such as type 2 diabetes mellitus,

hypertension, heart disease, gall bladder disease, and sleep apnea. Clearly,

this is a national health concern, and although about 30 to 40% of the obese

claim that they are trying to lose weight or maintain weight after weight

loss, current therapies appear to have little effect. None of the current

popular diets are working, and there is room for innovation. With the

advancing science of nutrition, several nutrients - low-glycemic-index

carbohydrates, 5-hydroxytryptophan, green tea extract, and chromium - have

been identified that may promote weight loss. The first two nutrients

decrease appetite, green tea increases the 24-h energy expenditure, and

chromium promotes the composition of the weight lost to be fat rather than

lean tissue. These have been assembled in efficacious doses into a new

functional food product and described in this review. The product is

undergoing clinical testing; each component has already been shown to

promote weight loss in clinical trials.

Green tea polyphenols and tannic acid act as potent inhibitors of phorbol

ester-induced nitric oxide generation in rat hepatocytes independent of

their antioxidant properties.

 

Srivastava RC, Husain MM, Hasan SK, Athar M.

 

Industrial Toxicology Research Centre, P.O. Box 80, M.G. Marg, Lucknow,

India.

 

The deleterious effects of excessive release of nitric oxide (NO) have been

implicated in the tissue damage and inflammation. In this study, the effect

of various flavonoids and other oxidant scavenging chemical agents have been

studied for their ability to inhibit 12-O-tetradecanoyl phorbol 13-acetate

(TPA)-induced NO generation in rat hepatocyte. Hepatocytes activated with

TPA (25-200 nM) released NO in a concentration- and time-dependent manner.

Green tea polyphenols (GTP) and tannic acid (TA) were most effective in

inhibiting TPA-induced NO generation (90%). These agents were also effective

in inhibiting NO formation when added 2 h following TPA addition. The other

oxidant scavengers, such as L-histidine, sodium azide, vitamin E and sodium

benzoate, were not found to be effective even up to 1.0 mM concentration.

These results suggest that TA and GTP are potent inhibitors of NOS activity

and the inhibition of TPA-induced NO generation by these polyphenols is

independent of their antioxidant activity. It is tempting to speculate that

Hepatothermic therapy of obesity: rationale and an inventory of resources.

 

McCarty MF.

 

Pantox Laboratories, San Diego, California 92109, USA.

 

Hepatothermic therapy (HT) of obesity is rooted in the observation that the

liver has substantial capacities for both fatty acid oxidation and for

thermogenesis. When hepatic fatty acid oxidation is optimized, the newly

available free energy may be able to drive hepatic thermogenesis, such that

respiratory quotient declines while basal metabolic rate increases, a

circumstance evidently favorable for fat loss. Effective implementation of

HT may require activation of carnitine palmitoyl transferase-1

(rate-limiting for fatty acid beta-oxidation), an increase in mitochondrial

oxaloacetate production (required for optimal Krebs cycle activity), and

up-regulation of hepatic thermogenic pathways. The possible utility of

various natural agents and drugs for achieving these objectives is

discussed. Potential components of HT regimens include EPA-rich fish oil,

sesamin, hydroxycitrate, pantethine, L-carnitine, pyruvate, aspartate,

chromium, coenzyme Q10, green tea polyphenols, conjugated linoleic acids,

DHEA derivatives, cilostazol, diazoxide, and fibrate drugs. Aerobic exercise

training and very-low-fat, low-glycemic-index, high-protein or vegan food

choices may help to establish the hormonal environment conducive to

effective HT. High-dose biotin and/or metformin may help to prevent an

excessive increase in hepatic glucose output. Since many of the agents

contemplated as components of HT regimens are nutritional or food-derived

compounds likely to be health protective, HT is envisioned as an on-going

lifestyle rather than as a temporary 'quick fix'. Initial clinical efforts

to evaluate the potential of HT are now in progress. Copyright 2001 Harcourt

Influence of tea catechins on the digestive tract.

 

Hara Y.

 

Food Research Institute, Mitsui Norin Co., Ltd., Shizuoka Pref., Japan.

 

Tea catechins undergo various metabolic changes after they are taken orally,

though a large percentage are excreted intact with the feces.

Epidemiological studies suggest a protective effect of tea against various

human cancers, including colon and rectum. The bactericidal property of tea

catechins plays several roles in the digestive tract. In the small

intestine, catechins inhibit alpha-amylase activity, and a certain amount is

absorbed into the portal vein. Although catechins are bactericidal, they do

not affect lactic acid bacteria. Including tea catechins in the diet for

several weeks decreases putrefactive products and increases organic acids by

lowering pH. These changes were achieved in tube-fed patients by

administering 100 mg of tea catechins (equivalent to a cup of green tea)

three times daily with meals for 3 weeks. When catechin administration

ceased, the effects reversed after 1 week. Catechins should be considered

further in colon carcinogenesis studies.

Hi Marcos,

 

Thank you so much for taking the time to forward that article about the

different types of teas. I guess snow tea is the white tea I mentioned? Do you

know? I wonder if that means it is still green tea?

 

Also I thought that oolong tea was sort of between green tea and black tea in

that it is half fermented. I will be copying this explanation for future

reference. May have to do more research on this subject. I hope to be able to

find some of the teas mentioned, if they are not entirely out of reach in price.

I like the thought of that snow tea making one feel very warm. This is

something good to hear when suffering from kidney yang deficiency along with

spleen chi deficiency and something I would like to have on hand for winter days

(maybe it will be possible to buy in a small quantity).

 

I wonder if the Chinese actually drink black tea in the winter too? This is

something I have never heard before, but then the Chinese I know hail from

Taiwan. Perhaps because it is mostly warmer there they do not drink black tea.

 

Best wishes,

 

Sarah

Kevin: I am curious about the formula w/bromelain, etc. you are using that

appears to be working for the finger joint arthritis pain.....do you mind

sharing? Are you using any chinese herbs in addition...just curious. I know a

young person with the same and only complaint...besides some slight fatigue.

Tongue pale, thin white coat. Pulse a little weak and slow is all. Thanks,

Twyla.

I was starting to get premature arthritis in my finger joints. All

gone! Beyond that, I'm not sure what it's particular scientifically

researched attributes are. Hope you'll post when you find out

more.

White tea,... another variety perhaps(fro green and black), but

could be snow tea, got to research that. Oolong means 'dragon', I

think, but if that is because of the place it grows, or...

When I read that on the snow tea, I thought: 'maybe we could

plant or use a suitable plant from a snowy mountain and it would

also have that heating effect?', maybe...(there is also that

'Tu-Mo' tibetan Qi-Gong for heating the body in extreme cold).

Yes, we know there are different customs in China depending on

the Province, to the north, south, to the sea, the mountains,

etc,

In the book Da Liu gives the Chinese name(and the Chinese

caracters for it) and they all have 'Ch´a' in them. In Portuguese

and Spanish, we use the word 'Cha' for tea, like the Chinese

apparently, of course we got it from them from the 'discovery'

days. In central Asia too 'teahouses' where called 'Chaikanas'.

 

Be well,

 

Marcos

We do in colloquial English too 'A cup o' char'.

 

The word spelled like that was also used in the past of a cleaning lady

'charwoman', but that apparently came from 'charred', presumably because of

soot from cleaning out fireplaces etc.

Speeding up the metabolism helps you burn fat faster and increases energy through that way, not really an energy-energy stimulant, it's too gentle

i totally agree with this!! and as with so many things all teas are

not created equal...a tea that is not fresh or overprocessed will

taste really ick. definitely get an organic green tea...a fresh

loose tea is even better. also you have to watch how long you steep

green tea for...i steep it for much less time than i do black tea b/c

i find it gets bitter if it's too strong...you could also try adding

some fresh lemon and a little honey until you get used to the taste.

luv laura

Claudette,

Just a bit of info on capsules for you.

Powders in capsules can sometimes be next to impossible to absorb if a person's digestion is very poor or compromised.
