Antioxidants In Green Tea Boost The Immune System
Drinking green tea might fend of the sniffles this winter. In a randomized controlled trial, 32% fewer participants taking green tea extract developed cold or flu symptoms compared to a placebo control group . The exact mechanisms behind this effect are unknown, but they could be related to the vitamin C content in green tea.
Chinese Green Teaspan Fired
The Chinese style of green tea is characterized by pan firing, where tea leaves are heated in a basket, pan or mechanized rotating drum to halt the oxidation process.
Chinese green teas may be fired more than once during processing, depending on the style of tea being produced. These firings may take place in wicker baskets, steel wok-like pans, metal drums or other containers over charcoal, gas flame, electric heat or hot air, depending on the final flavor outcome desired.
The flavor can be altered greatly depending on the number and type of firings, but generally a pan fired Chinese green tea takes on a yellowish-green or dark green color and impart a grassy, earthy, roasted flavor.
Some popular pan fired Chinese green teas include:
- Dragonwell: A smooth, flat, sword-shaped appearance and pan-fired toasty taste give this tea its characteristic look and flavor no other green tea-producing region has been able to duplicate. It is considered a classic pan-fired Chinese green tea.
- Gunpowder: Fired in perforated metal tumbler that tosses the leaves around in a figure eight pattern Gunpowder tea takes is name from the pellet-like shape of the finished leaf.

Effect Of Egcg On Diabetes
A study by Waltner-Law et al. provided compelling in vitro evidence that EGCG decreases glucose production of H4IIE rat hepatoma cells. The investigators showed that EGCG mimics insulin, increases tyrosine phosphorylation of the insulin receptor and the insulin receptor substrate, and reduces gene expression of the gluconeogenic enzyme phosphoenolpyruvate carboxykinase. Recently, green tea and green tea extracts were demonstrated to modify glucose metabolism beneficially in experimental models of type II diabetes mellitus . In addition, EGCG ameliorates cytokine-induced cell damage in vitro and prevents the decrease of islet mass induced by treatment with multiple low doses of streptozotocin in vivo .
Lambert et al. showed that intragastric administration of EGCG at a dose of 75 mg/kg resulted in a Cmax of 128 mg/l total plasma EGCG and a terminal half-life of 83 minutes. Furthermore, in humans an oral intake of EGCG at a dose of 50 mg resulted in a Cmax of 130 mg/l total plasma EGCG and a terminal half-life of 112 minutes . These results indicate that rodents must be orally administered 100- to 600-fold more EGCG to achieve similar plasma concentrations as those found in humans. Total plasma EGCG concentrations shown to be efficacious in mice and rats can be reached by an intake of low to moderate doses of EGCG in humans.

The Most Convenient Place To Buy Green Tea
Virtually everyone has an account on Amazon, making it a convenient place to buy tea.
The main problem is the extremely large selection. Its nice to have options, obviously, but most of those options just arent very good. It can be hard to find the quality offerings among all the junk, but they are there.
For sencha, the best option is the excellent organic Sencha from Rishi tea. It is reasonably priced and a far better tea than you would expect to get for the cost.
For Dragon Well, try this organic tea from Golden Moon which is another great value buy.
Good gyokuro is almost impossible to find on Amazon, but there are two worth getting: the Imperial Gyokuro from Chado is expensive, but very high quality and Ochas organic gyokuro is not quite as high quality, but still very good and considerably less expensive.

Losing weight is not as easy as adding more weight, but with good exercise, healthy diet and high quality nutritional supplement like the Green tea extract, people can lose weight faster than they can imagine. The popular celebrity doctor took the pride of revealing the amazing benefits of this nutritional supplement to the world. If you were familiar with Dr. Oz, you would know that he does not talk about any nutritional supplement without a substantial evidence.
Green tea extract contains a high concentration of EGCG catechin. From studies conducted, it shows that the supplement can activate the thermogenic fat-burning properties of the body. In the study conducted, about 690 mg of catechins taken for 12 weeks actually reduced the entire fat area, thickness of skinfold, waist circumference and the subcutaneous fat region of the subject. At the same time, another subject who took placebos did not show any significant improvement in these areas.
The way catechin works in the Green tea extract weight loss pill is amazing. It helps to inhibit an enzyme known as COMT which reduces the function of norepinephrine in the body. Catechin creates an enabling environment for the fat-burning hormone to thrive. This is why people, who consume the Green tea extract for weight loss, lose weight naturally.

A federal review in Canada concluded that while the majority of people who take green-tea extract in any form, do so without harm, they also found that there may be a link between the use of green tea extract and a risk of rare and unpredictable liver injury.
The warnings are nothing newincluding in the U.S. In 2014, The American College of Gastroenterology released guidelines on drugs and herbal supplements that can cause liver injury. Topping the list of herbals? You guessed it: green-tea extract. Some pills, they note in the press release, can contain more than 700 milligrams of catechins , whereas a cup of green tea contains 50 to 150 mg, and people tend to take these pills multiple times a day.
In animal studies, when some strains of mice are given high doses of EGCG , they develop acute liver injury that looks like Tylenol toxicity, explains Herbert Lloyd Bonkovsky, M.D., gastroenterology professor at Wake Forest Baptist Health. He notes that some peoplebecause of factors like geneticsmay be more prone to liver damage than others. Fasting also increases the absorption of catechins, meaning there may be a higher risk of injury for people who are trying to lose weight, he says.
Bonkovsky also notes that while drinking green tea is almost always safe, there have been some reports of people developing liver injury after consuming large amounts, like eight or 10 cups a day.

Some studies indicated that green tea has an antiproliferative activity on hepatoma cells and a hypolipidemic activity in hepatoma-treated rats, as well as the prevention of hepatoxicity and as a preventive agent against mammary cancer post-initiation . Green tea catechins could also act as antitumorigenic agents and as immune modulators in immunodysfunction caused by transplanted tumors or by carcinogen treatment . Moreover, green tea, its extract, and its isolated constituents were also found to be effective in preventing oxidative stress and neurological problems .
The effectiveness of green tea in treating any type of diarrhea and typhoid has been known in Asia since ancient times .

Steeping Brewing And Serving
Steeping, or brewing, is the process of making tea from leaves and hot water, generally using 2 grams of tea per 100 millilitres of water or about 1 teaspoon of green tea per 150 ml cup. Steeping temperatures range from 61 °C to 87 °C and steeping times from 30 seconds to three minutes.
Generally, lower-quality green teas are steeped hotter and longer while higher-quality teas are steeped cooler and shorter, but usually multiple times . Higher-quality teas like gyokuro use more tea leaves and are steeped multiple times for short durations. Steeping too hot or too long results in the release of excessive amounts of tannins, leading to a bitter, astringent brew, regardless of initial quality. The brew’s taste is also affected by the steeping technique two important techniques are to warm the steeping container beforehand to prevent the tea from immediately cooling down, and to leave the tea leaves in the pot and gradually add more hot water during consumption.
