To make green tea, the leaves are quickly steamed or heated to stop oxidation, the chemical process that causes browning. To make black tea, the leaves are crushed, torn, curled, or rolled and allowed to oxidize before being dried. This additional processing step degrades some of the flavonoids. As a result, black tea has slightly lower amounts of flavonoids than green tea.
The oldest tea producing region in Japan is Uji, located near the former capital of Kyoto. It is thought that seeds sent by Eisai were planted in Uji, becoming the basis of the tea industry there. Today, Japan's most expensive premium teas are still grown in Uji. The largest tea producing area today is Shizuoka Prefecture, which accounts for 40% of total Japanese sencha production. Other major tea producing regions include the island of Kyushu and the prefectures of Shiga, Gifu, and Saitama in central Honshu.
Forsythia fruit is the dried seed pod of Forsythia suspensa, a lovely bright yellow flowering bush that is among the first spring blooms in many northern climates. Native to China, forsythia fruit is used in Traditional Chinese Medicine (TCM) for detoxifying. Because of its detoxifying qualities, forsythia fruit often finds its way into TCM formulas to support the kidneys and skin.
Our green tea is passed through a steaming treatment before rolling. Steaming applies light heat to the leaves to help halt the oxidation process before the leaves are rolled into shape. Steaming also helps expose the fresh, grassy flavor of the leaf. Green tea leaves are not allowed to oxidize after rolling, which is why they remain light color and flavor.
Day 28: Honesty time — I took several days off. I went away for the long weekend, and I overindulged in Mexican food, wine tastings, and cherry ice cream. When I got home, I was nursing an exhausted body and a bad case of bloat. The solution? To drink my final cup of tea. After drinking it, I went to bed feeling refreshed and lighter, then woke up the next morning ready for a workout and a day back at work.
Green tea is processed using either artisanal or modern methods. Sun-drying, basket or charcoal firing, or pan-firing are common artisanal methods. Oven-drying, tumbling, or steaming are common modern methods. Processed green teas, known as aracha, are stored under low humidity refrigeration in 30- or 60-kg paper bags at 0–5 °C (32–41 °F). This aracha has yet to be refined at this stage, with a final firing taking place before blending, selection and packaging take place. The leaves in this state will be re-fired throughout the year as they are needed, giving the green teas a longer shelf-life and better flavor. The first flush tea of May will readily store in this fashion until the next year's harvest. After this re-drying process, each crude tea will be sifted and graded according to size. Finally, each lot will be blended according to the blending order by the tasters and packed for sale.
Usucha, or thin tea, is prepared with approximately 1.75 grams (amounting to 1.5 heaping chashaku scoop, or about half a teaspoon) of matcha and approximately 75 ml (2.5 oz) of hot water per serving, which can be whisked to produce froth or not, according to the drinker's preference (or to the traditions of the particular school of tea). Usucha creates a lighter and slightly more bitter tea.
Most importantly, EGCg and other catechins counteract the effects of free radicals from the likes of pollution, UV rays, radiation, and chemicals, which can lead to cell and DNA damage. Since over 60% of the catechins in matcha are actually EGCg, a daily matcha regimen can help restore and preserve the body’s integral well-being and balance. Read more on our Change The Odds Page.
Gyokurocha: In this variety, the tea leaves are plucked from the tip of the branches. When brewed, the color is clear green. Being picked from the tip, this variety has the best taste and fragrance, and this variety is also considered the best in terms of health. Furthermore, it is less bitter, as it contains lesser tannin and caffeine since the plucked leaves are younger and still budding. The only drawback to gyokurocha is the high cost, but as we all know, truly high-quality solutions for health never come cheap!

In 2013, global production of green tea was approximately 1.7 million tonnes, with a forecast to double in volume by 2023. As of 2015, China provided 80% of the world's green tea market, leading to its green tea exports rising by 9% annually, while exporting 325,000 tonnes in 2015. In 2015, the US was the largest importer of Chinese green tea (6,800 tonnes), an increase of 10% over 2014, and Britain imported 1,900 tonnes, 15% more than in 2014. In 2015, Kenya was the largest exporter of black tea in the world (443,000 tonnes).
A well-known compound found in green tea is called EGCG (which stands for epigallocatechin-3-gallate). EGCG is associated with enhanced metabolic activities that may prevent weight gain or assist with weight maintenance. Some of the ways that EGCG seems to work is by boosting thermogenesis (the body producing heat by using energy) and suppressing appetite, although not every study has found evidence that these effects are substantial.
Flavan-3-ols, the type of flavonoids found in green tea and other teas, provide many of the anti-aging effects of green tea. Catechins in various types of teas are the polyphenols that seem to have the most potent antioxidant effects, according to Natural Standard, the leading and most respected reviewer of herbal compounds. Specific flavan-3-ols found in green tea include monomers (catechins) called:
Rooibos is being heavily hyped by producers and distributors as a new health beverage. Unlike true “tea,” it is caffeine-free and low in tannins. It contains minimal amounts of calcium, potassium, iron, zinc, magnesium and much less fluoride than found in real teas. Studies have shown that Rooibos does contain antioxidants and therefore might have some of the health benefits of green tea, but very little research has confirmed this. I found only 17 scientific studies of Rooibos compared to more than 1,000 on green tea. So far, none suggest that Rooibos is the health equivalent of green tea.
In this traditional Japanese preparation, the powder is sifted through a fine mesh sieve and measured into a special bowl called a chawan. Hot water is added slowly while whisking briskly in a W pattern with a bamboo whisk called a chasen until smooth with a foamy froth on top. Matcha can have a slight astringent note and is usually served with a small sweet confection called a wagashi. Because of this complementary relationship with sweets and reputed green tea health benefits, it has become a favorite ingredient for chefs and confectioners.
And not all the science has been favorable to tea. A report in the March 1 edition of The New England Journal of Medicine looking at green tea consumption in humans, found no effect on stomach cancers once adjustments were made for other factors that could affect risk. Those other factors included sex, age, history of stomach ulcer, use of tobacco or alcohol, and other dietary habits.
Several varieties of green tea exist, which differ substantially based on the variety of C. sinensis used, growing conditions, horticultural methods, production processing, and time of harvest. Although there has been considerable research on the possible health effects of consuming green tea regularly, there is little evidence that drinking green tea has any effects on health.
Those magical catechins also have tons of potential in helping people with heart issues. “Catechins present in green tea have the ability to prevent atherosclerosis, hypertension, endothelial dysfunction, ischemic heart diseases, cardiomyopathy, cardiac hypertrophy and congestive heart failure by decreasing oxidative stress, preventing inflammatory events, reducing platelet aggregation and halting the proliferation of vascular smooth muscle cells,” explains the author of the study, published in the Chinese Journal of Natural Medicines.
Drinking green tea or taking green tea supplements decreases the blood concentration of total cholesterol (about 3–7 mg/dL), LDL cholesterol (about 2 mg/dL), and does not affect the concentration of HDL cholesterol or triglycerides. A 2013 Cochrane meta-analysis of longer-term randomized controlled trials (>3 months duration) concluded that green tea consumption lowers total and LDL cholesterol concentrations in the blood.
African red tea's naturally sweet taste makes it easy to keep your added sugar intake low. According to the American Heart Association, most Americans consume too much added sugar in their diet, which can lead to weight gain and obesity. The association recommends consuming no more than 6 to 9 teaspoons of added sugar a day. Added sugar, and especially drinks high in added sugar such as sodas, have no nutritional benefits whatsoever, unlike rooibos, which has a number of associated health benefits.
In 1904, Benjamin Ginsberg ran a variety of experiments at Rondegat Farm, finally curing rooibos. He simulated the traditional Chinese method of making Keemun by fermenting the tea in barrels. The major hurdle in growing rooibos commercially was that farmers could not germinate the rooibos seeds. The seeds were hard to find and impossible to germinate commercially.
All commercial tea produced in Japan today is green tea, though for a brief period black tea was also produced in the late 19th and early 20th centuries. Japanese tea production is heavily mechanized, and is characterized by the use of modern technology and processes to improve yields and reduce labor. Because of the high cost of labor in Japan, only the highest quality teas are plucked and processed by hand in the traditional fashion.

While there are some published studies on various ingredients often found in detox teas, I haven't seen any research on the teas themselves, particularly in the precise formulas they're prescribed (that research isn't required for the teas to be sold, by the way). That means that using detox teas leaves unanswered questions about if and how they work, how they should be used, how much may be too much, and possibly who shouldn't use them. If you're unsure, or are planning to start drinking them, talk to your doctor, nutritionist, or health care provider. Just be sure he or she doesn't have a vested interest in the sale of the product you're considering: If they happen to be selling or endorsing it, seek a second opinion.
2. Enables digestion: Red tea is caffeine-free and also free of tannins. This element is present in other teas and is known to cause digestive issues among many people. Red tea is a storehouse of antispasmodic elements, preventing diarrhea and gastric issues. It has no oxalic acid, this makes it suitable for those who are prone to developing kidney stones.
Both nutritionists we spoke to agree that drinking tea when you wake up and before bed can help your system rev up and calm down, depending on which variety you choose. If you’re a tea fanatic, work in a few cups throughout the day: Unless you’re sensitive to caffeine, you can probably handle five to seven cups a day without any negative side effects, says Lagano.
About two to four grams of matcha is placed into the bowl, traditionally using a bamboo scoop called a chashaku, and then about 60-80 ml of hot (70–85 °C or 158–185 °F, not boiling,) water is added. The mixture is then whisked to a uniform consistency, using a bamboo whisk known as a chasen. There must be no lumps left in the liquid, and no ground tea should remain on the sides of the bowl. Because matcha may be bitter, it is traditionally served with a small wagashi sweet (intended to be consumed before drinking), but without added milk or sugar. It usually is considered that 40 g of matcha will provide for 20 bowls of usucha or 10 bowls of koicha:
The best Matcha Green Tea comes from the first flush, baby green tea leaves that grow during the spring. Only the newest buds of the shade grown tea plants are hand-picked for Premium Matcha production. The window for ideal Matcha Green Tea growth is very limited, which is one of the reasons that Matcha is one of the more expensive teas on the market.
Every checkout line magazine seems to have their own version of “the” detox diet. Our tea isn’t a fad, it’s based in Traditional Chinese Medicine. We’ve formulated this blend to work in harmony with your body’s natural detoxification process, instead of shocking it with overly active plants or an intense cleanse. Schisandra berry is one of the main ingredients and is unique in that it has all five tastes. In combination with chicory root, dandelion root and lycium fruit (a.k.a. goji), this blend helps to stimulate your liver’s natural process of detoxification,* giving your liver the love it deserves.
Detox teas that combine caffeine with diuretics can trigger the loss of water weight. Just two cups of water weighs one pound on a scale, so shedding fluid can make you look and feel lighter–even if you haven't lost an ounce of body fat. Detox teas can also trigger a laxative effect, which causes your body to eliminate waste from your GI tract, another result that can make your stomach flatter, and allow you to feel lighter, even if your lean-to-fat ratio remains exactly the same. If this quick-fix effect gives you the confidence boost and motivation you need to start eating healthier and working out–the real keys to getting healthy and lean–terrific (assuming the teas are even safe to drink–see below). Just remember: If you go back to your former less-than-stellar eating or exercise habits, or stop drinking the tea, you can gain the weight right back just as quick as you dropped it.
Sencha: Sencha comes from the same plant, but in this green tea variation, the leaves are from the middle of the branch and are bigger, older, and less tender than Gyokurocha. This variety gives a clear, light green tea when brewed as well. Naturally, it is more bitter and stronger than the former variety. Being of less noble origin (middle of the branch) and having more caffeine and tannin, it is cheaper and more popular than Gyokurocha.
9. Make it a point to learn at least one new thing each day: the name of a flower that grows in your garden, the capital of a far-off country, or the name of a piece of classical music you hear playing in your favorite clothing boutique as you shop. If it’s time for bed and you can’t identify anything you’ve learned that day, take out your dictionary and learn a new word.
But matcha didn’t skyrocket to celeb status on health merits alone. As we said back in 2011, wheatgrass is healthy, too, but we’re not seeing it in every other bakery and café. Matcha has flavor going for it—grassy, pleasantly vegetal, and slightly bitter—and a brilliant natural color that makes baked goods (like rainbow cookies) stand out from the crowd in busy bakeries (and on Instagram).
The reason that green tea has more health benefits attached to it than black tea is due to the processing. Black tea is processed in a way that allows for fermentation whereas green tea’s processing avoids the fermentation process. As a result, green tea retains maximum amount of antioxidants and poly-phenols the substances that give green tea its many benefits.
Experts emphasize that the primary thrust of scientific research has been on the pure tea products -- green, black, or oolong tea, derived from a plant called Camellia sinensis. All of the many other "herbal" or "medicinal" teas found in supermarkets and health food stores may be tasty, and may be good, bad, or indifferent for your health -- but they haven't been the focus of concentrated research, says John Weisburger, PhD, of the American Health Foundation.
Matcha leaves are grown on green tea bushes kept under shade. The shade increases the amount of chlorophyll content in the leaves, which is what makes them bright green and full of nutrients. The leaves are picked by hand and the stems and veins are removed. According to Cheadle, the leaves are traditionally ground by granite stones into a super fine powder. “It takes an hour to grind the leaves, and it’s done in the dark to protect the nutrients,” she says.
Day 14: At halfway through my detox, I finally officially figured out what works for me and my body. The plan: my standard first-thing-in-morning cup of coffee, then an iced version of the tea to drink with me throughout the day. I sip it all day long, and it’s both refreshing and hydrating. I can very honestly say I feel AWESOME. I’m having no kinds of digestive problems, I feel lighter while running at the gym, and my stomach is significantly less bloated and more toned.
Although numerous claims have been made for the health benefits of green tea, human clinical research has not provided conclusive evidence of any effects. In 2011, a panel of scientists published a report on the claims for health effects at the request of the European Commission: in general they found that the claims made for green tea were not supported by sufficient scientific evidence. Although green tea may enhance mental alertness due to its caffeine content, there is only weak, inconclusive evidence that regular consumption of green tea affects the risk of cancer or cardiovascular diseases, and there is no evidence that it benefits weight loss.
Total Tea Gentle Detox tastes great and is fast acting. Initially, you may have to go to the washroom frequently as the tea first cleanses the colon. After 2-3 days, bloating and any discomfort will disappear. You will also start to notice an improvement in your energy levels and productivity. And soon after, you will see visible changes in your appearance, get a flat tummy, and be highly motivated to eat and live healthily.
Green tea also seems to boost physical performance, increase exercise endurance, and decrease reaction time, and there are many, many such studies showing these effects from caffeine, although other ingredients in green tea may aid this effect. Caffeine, and green tea’s, ability to mobilize fatty acids in fat tissue to make them more easily available for use as energy also seems to aid physical performance. In one study, caffeine was shown to significantly increase physical performance (exercise endurance and exertion). The antioxidants in green tea may also help prevent tissue damage during physical exertion as well.
The natural ingredients included in this detox tea have been used for ages to promote various aspects of human health. That being said, your body does quite well at detoxing itself through the healthy functioning of your liver and kidneys. There are few risks associated with drinking a tea like this one, so if you enjoy the flavor anyway, you could reap a few additional benefits.
