According to the National Cancer Institute, the polyphenols in tea have been shown to decrease tumor growth in both animal and laboratory studies. Researchers believe that it is the high level of polyphenols in tea that help kill cancerous cells and stop them from growing, although the exact mechanism by which tea inhibits and prevents cancerous cells is uncertain.
Japanese green teas have a thin, needle-like shape and a rich, dark green color. Unlike Chinese teas, most Japanese teas are produced by steaming rather than pan firing. This produces their characteristic color, and creates a sweeter, more grassy flavor. A mechanical rolling/drying process then dries the tea leaves into their final shape.[54] The liquor of steamed Japanese tea tends to be cloudy due to the higher quantity of dissolved solids.[56]

Apart from causing premature aging, free radicals are also responsible for causing certain types of cancer. The catechins present in green tea neutralize these free radicals, prevent the formation of carcinogens like nitrosamines and reduce the risk of cancer for people who regularly consume it. Green tea is now being clinically used and prescribed as a home remedy to aid in the prevention of cancer, particularly for those patients at high risk for cancer in the colon, rectum, pancreas, and intestines.


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.
Nine health benefits of turmeric tea Turmeric is a spice that contains curcumin, which seems to have anti-inflammatory and immune-boosting properties. In this article, we look at nine health benefits of turmeric tea. These include cancer prevention, protection against liver damage, and improved immune function. We also explain how to prepare turmeric tea. Read now
The available research on matcha includes a small pilot study published in the International Journal of Sports Nutrition and Exercise Metabolism in 2018. For the study, women consumed matcha green tea beverages before a 30-minute brisk walk. Researchers found that matcha consumption enhanced fat oxidation (the breakdown of fat into smaller molecules to be used for energy) during the walk.
Another big draw health benefit-wise is that matcha, like green tea, is loaded with antioxidants. A study, published in 2014, found the plant also had antimicrobial properties, particularly the four types of catechins (antioxidant properties flavonoids) it contains, against a few different types of microorganisms. Yet another study, published in Nature, proved that catechins inhibit the growth of a bacteria called Fusobacterium nucleatum — the bacteria that causes cavities and periodontal disease.

Generally, the leaves undergo an oxidation (often termed "fermentation" in common tea processing terminology). This process produces the distinctive reddish-brown colour of rooibos and enhances the flavour. Unoxidised "green" rooibos is also produced, but the more demanding production process for green rooibos (similar to the method by which green tea is produced) makes it more expensive than traditional rooibos. It carries a malty and slightly grassy flavour somewhat different from its red counterpart.[3]

I'll be the first to admit I am NO matcha tea expert. However, I do enjoy this tea a lot. It has a very green, planty taste kind of. It is a lot stronger than something like generic green tea bags from different brands I have tried. I use a tiny whisk to stir it up in hot water and drink. There are some grains at the bottom of the cup that I drink, but it isn't as crazy as greek coffee or anything like that with a thick sludge at the bottom. I like that this gives me the benefits of green tea without having to down as many cups of it, because the matcha is much more potent.
Matcha (抹茶, Japanese pronunciation pronounced [mat.tɕa], English /ˈmætʃə/[1][i]) is finely ground powder of specially grown and processed green tea leaves. It is special in two aspects of farming and processing: the green tea plants for matcha are shade-grown for about three weeks before harvest and the stems and veins are removed in processing. During shaded growth, the plant Camellia sinensis produces more theanine and caffeine. The powdered form of matcha is consumed differently from tea leaves or tea bags, and is dissolved in a liquid, typically water or milk.

In conclusion, whilst there is a considerable body of evidence for green tea with some of it suggesting a positive effect, it is difficult to be definitive as to its health benefits.
Green tea has slightly more antioxidants compared to black tea, although both are still great sources. The ORAC value (antioxidant content) of brewed black tea is 1,128 while green tea is slightly higher at 1,253. Black tea and green tea both contain antioxidants, including polyphenols. Some research shows that green tea contains more than four times the catechins that black tea does. Both types can contribute antioxidants to your diet and have been shown to have antiviral, anti-inflammatory, detoxifying and immune-stimulating effects.
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.

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.
It depends not only on the processing method the tea producers use, but also on the cultivation practices the tea growers use. What time of year is the tea plucked? How is the plant pruned? What parts of the plant are plucked? Are the plants treated with chemicals or are they organically grown? What kind of heat is applied to the tea leaves to stop oxidation? How are the tea leaves shaped, rolled and dried? Are the leaves left whole or cut in smaller pieces?

Recently, green tea has replaced many other beverages as it helps in weight loss. Drink a cup or two of green tea every morning and you are bound to lose a few pounds of excess weight over a week or so.

In Canada, green tea is defined as a dry-based mixture and the sale of it is regulated by the Canadian Food Inspection Agency (CFIA). It is one of the foods for which a standard of identity is specified according to the Food and Drug Regulations. It should contain not less than 33% water-soluble extractive (determined by official method FO-37 which is the determination of water-soluble extractive in tea) and the total ash should between 4% to 7%.[92]


Green tea is processed and grown in a variety of ways, depending on the type of green tea desired. As a result of these methods, maximum amounts of polyphenols and volatile organic compounds are retained, affecting aroma and taste. The growing conditions can be broken down into two basic types − those grown in the sun and those grown under the shade. The green tea plants are grown in rows that are pruned to produce shoots in a regular manner, and in general are harvested three times per year. The first flush takes place in late April to early May. The second harvest usually takes place from June through July, and the third picking takes place in late July to early August. Sometimes, there will also be a fourth harvest. It is the first flush in the spring that brings the best-quality leaves, with higher prices to match.
In one study, daily consumption of green tea was correlated with a lower risk of death from any cause; an increase of one cup of green tea per day was linked with a 4% lower risk of death from any cause.[13] A separate analysis found that an increase of three cups of tea or green tea per day was associated with a small lower risk of total mortality in Asians and women.[17]
The leaves are used to make a herbal tea that is called by the names: rooibos, bush tea (especially in Southern Africa), or redbush tea (predominantly in Great Britain). The tea has been popular in Southern Africa for generations, but is now consumed in many countries worldwide. It is sometimes spelled rooibosch in accordance with the original Dutch. The tea has a taste and color somewhat similar to hibiscus tea, or an earthy flavor like yerba mate.
Asian countries like Japan and China are the biggest producers of green tea (they produce the best quality too) and are also its biggest consumers. Green tea available in other markets is found in far smaller quantities than black tea. Moreover, it is still gaining popularity, and you can get it at any modern shop. You can also order it from a local tea supplier, over the phone or on the internet. It is almost invariably imported from China (cheaper) and Japan (more expensive) and is packed in sealed packs of 200 grams, 250 grams, and 500 grams. Buy smaller quantities if possible, so that you get to make a fresh brew. Also, always check the date of manufacturing and packing before you buy.

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. 

Green tea is a longtime treasure of China and Japan that is gaining popularity in America. It’s easy to understand why: the best green tea leaves are heated or steamed right after harvest, preserving their all-natural flavor and resulting in a nourishing beverage containing antioxidants. With about half the caffeine of black tea, you get the health benefits of green tea in every gentle cup. You can buy green teas in either loose-leaf or green tea bags.

Detox teas are great for flushing out toxins from your body. Toxins like harmful chemicals and free oxygen radicals lead to increased stress levels in the body. Stress slows down metabolism, weakens immunity, and increases the level of inflammation. And you start to gain weight, find it difficult to lose weight, suffer from constipation, gastritis, liver problems, and disturbed sleep, and feel tired all the time. The antioxidants and other phytonutrients in detox teas deactivate the harmful effects of toxins, cleanse the digestive tract, and relax your brain – promoting weight loss and better health. So, let’s get to know the top 10 detox teas that you can buy and start shedding the extra flab. Scroll down.
Over a thousand years ago, matcha came to Japan as an aid to meditation practice. During long hours of sitting, monks would drink matcha to remain alert yet calm. Modern science has recently confirmed the lessons of centuries of tradition. Matcha is rich in L-Theanine, a rare amino acid that actually promotes a state of relaxation and well-being by acting upon the brains functioning. While stress can induce beta waves an excited, more agitated state, L-Theanine creates alpha waves, which lead to a state of relaxed alertness. And while L-Theanine is common in all tea, matcha may contain up to five times more of this amino acid than common black and green teas.

It is a natural, organic green tea which has been the heart of the famous Japanese tea ceremony for over 900 years. The Buddhist monks honored matcha tea as the ‘health elixir’ for its potential to heighten the concentration and enhance metabolism. Originating in China in the 9th century, this was used as a drug for curing various ailments. However, its word somehow got elapsed in China. It was only after the Zen Buddhist monks from Japan realized its true potential at the end of the twelfth century, the perfection in the cultivation of these leaves picked up. Matcha is still scarcely grown accounting for just 0.6% of total tea yield.


Just have a cup of hot green tea after some rigorous exercise and you will be ready for a few more sets in no time. Furthermore, it effectively counters muscular pain due to overexertion of muscles. Although green tea isn’t widely consumed due to the presence of energy drinks in the market, if you visit Japan and China, you will see that green tea is the premier beverage used by practitioners of martial arts and various other sports.
In 1994, Burke International registered the name "Rooibos" with the US Patent and Trademark Office, thus establishing a monopoly on the name in the United States at a time when it was virtually unknown there. When the plant later entered more widespread use, Burke demanded that companies either pay fees for use of the name, or cease its use. In 2005, the American Herbal Products Association and a number of import companies succeeded in defeating the trademark through petitions and lawsuits; after losing one of the cases, Burke surrendered the name to the public domain.[13]
The Alzheimer's Society commented that "this study adds to previous research that suggests green tea might help to reduce the risk of Alzheimer's disease. However, the researchers used a far higher dose of the active green tea chemical than would ever be found in the human body. More research is needed to see whether green tea is protective at a much lower dose, and to understand the mechanism involved."
The free radicals created in the body are responsible for corroding the body in various ways, one of which we see as the signs of aging and its related symptoms. Antioxidant-rich green tea neutralizes the oxidants or free radicals present in the body. The catechin polyphenols present in it are hugely responsible for its antioxidizing effects, the most powerful among them being the epigallocatechin gallate. Therefore, regular consumption of green tea can effectively delay the signs and symptoms of aging.

One of Japan’s own Zen priests studying in China’s Buddhist monasteries returned to Japan in the early 12th century with tea plant seeds and bushes. The young priest, called Eisai, used his experience in China growing and drinking “beaten tea” to popularize what he called “the way of tea” as a meditation ritual within his community of Japanese Buddhist monks. Eventually, he spread the tea drinking custom throughout the rest of Japan.
Researchers from the Netherlands confirmed in a recent study that two green tea compounds, L-theanine and caffeine, can significantly boost levels of attention and alertness, building on what is already known about the brain benefits of green tea. The drink is less likely to make you jittery and anxious than other energy-boosting drinks, because it contains lower levels of caffeine than other teas or coffee. In another study published in the American Journal of Clinical Nutrition, researchers discovered that drinking just one cup of green tea a day made people age 55 and older 38 percent less likely to experience a decline in their mental abilities. Drinking a second cup daily made them 54 percent less likely to show mental declines.
Although numerous claims have been made for the health benefits of green tea, human clinical research has not provided conclusive evidence of any effects.[2][7][11] 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.[7] 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.[2]

Additionally, rooibos is a source of two comparatively rare antioxidants, aspalathin and nothofagin. Aspalathin helps to modify hormones in the body and reduces the output of adrenal hormones specifically, thus reducing stress and helping to inhibit metabolic disorders. Aspalathin also helps to regulate blood sugar and therefore can play a role in reducing the risk of Type 2 diabetes and excessive fat production. The antioxidant nothofagin also demonstrates significant anti-inflammatory activity and, along with aspalathin, may help to reduce the risk of Alzheimer’s disease. Both appear to protect nerves.


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.[32] 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.[33]
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:

Day 1: So you’re supposed to drink your tea first thing in the morning (or before a workout), but I didn’t receive my package until after arriving home for the day (in the early evening). Since I am a slave to my own desire for instant gratification, I said “Screw the rules!” and made my first cup right then and there. Immediate observation: It’s actually pretty delicious. I don’t consider myself a tea connoisseur by any means, so I was pleasantly surprised. I didn’t think it needed the recommended addition of honey.
Rooibos contains polyphenols that have anti-inflammatory, antiviral, and antimutagenic qualities. Polyphenols are organic chemicals that are often praised for their antioxidant capabilities. Studies suggest that regularly drinking organic red rooibos tea provides the liver with potent antioxidants, helping the organ to improve detoxification. Antioxidants act as scavengers of free radicals throughout the body, which are detrimental byproducts of cell metabolism that can cause cancer and heart diseases. Aspalathin and nothofagin are two other vital antioxidants that rooibos tea contains, making it a great beverage to boost your immune system and protect your body against all types of diseases.
Rooibos tea is also known for its beneficial effects on those suffering from colic or diabetes. It also has the ability to cure headaches, insomnia, asthma, eczema, bone weakness, hypertension, allergies, and premature aging. This tea is absolutely free from caffeine content and is also low in tannins. Drinking rooibos tea can further ease severe stomach cramps and boost the immune system.
Matcha typically has more caffeine content than green tea, similar caffeine to black tea, and less caffeine than brewed coffee. Because matcha is produced from shade-grown tea bushes, the tea leaves tend to retain more of their caffeine content. In addition, since you’re consuming the ground tea leaf when sipping matcha, you’re ingesting more caffeine content than you would from the extraction of steeped green or black tea leaves. Like all drinks cultivated from caffeinated plants, however, a specific level of caffeine per cup of matcha tea will depend on the how the matcha was processed and prepared. Be sure and read the packaging carefully or ask your tea supplier directly for the caffeine information specific to the matcha you are buying.
can increase energy and mental focus. Green tea contains a small amount of caffeine, which a 2008 study in Nutrition Bulletin found can improve mood, cognitive function and physical performance. Green tea contains less caffeine than does coffee, and provides L-theanine, an amino acid shown to promote a state of calm awareness. Result: green tea provides the benefits of alertness associated with caffeine without the “jittery” feeling often experienced as a side effect of coffee.
According to Record of Gaya cited in Memorabilia of the Three Kingdoms, the legendary queen Heo Hwang-ok, a princess of the Ayodhya married to King Suro of Gaya, brought the tea plant from India and planted it in Baegwolsan, a mountain in current Changwon.[67]:3 However, it is a widely held view that systematic planting of tea bushes began with the introduction of Chinese tea culture by the Buddhist monks around the 4th century.[68] Amongst some of the earliest Buddhist temples in Korea, Bulgapsa (founded in 384, in Yeonggwang), Bulhoesa (founded in 384, in Naju) and Hwaeomsa (founded in Gurye, in 544) claim to be the birthplace of Korean tea culture.[68] Green tea was commonly offered to Buddha, as well as to the spirits of deceased ancestors.[68] Tea culture continued to prosper during the Goryeo Dynasty, with the tea offering being a part of the biggest national ceremonies and tea towns were formed around temples.[69] Seon-Buddhist manners of ceremony prevailed.[69] During the Joseon Dynasty, however, Korean tea culture underwent secularization, along with the Korean culture itself.[69] Korean ancestral rite jesa, also referred to as charye (차례; 茶禮, "tea rite"), has its origin in darye (다례; 茶禮, "tea rite"), the practice of offering tea as simple ancestral rites by the royal family and the aristocracy in Joseon.[69]

The use of matcha in modern drinks has also spread to North American cafés, such as Starbucks, which introduced "Green Tea Lattes" and other matcha-flavoured drinks after matcha became successful in their Japanese store locations. As in Japan, it has become integrated into lattes, iced drinks, milkshakes, and smoothies.[14] A number of cafes have introduced lattes and iced drinks using matcha powder. It has also been incorporated into alcoholic beverages such as liqueurs and matcha green tea beers.[citation needed]
If not taken with sugar, the alkaline nature of green tea helps reduce the blood glucose level. Moreover, the antioxidant and astringent qualities of green tea ensure good health and better functioning of the pancreas. Improving the function of the pancreas means a more efficient and regulated secretion of insulin and the subsequent improvement in decomposing and absorbing of sugar. This increase in effective functions can help prevent the onset of diabetes.
In fact, there is no hard evidence backing the claims made by tea companies that their detox teas actually purify human cells. However, high-quality teas can help support the body’s natural daily process of detoxification—just as much as other foods and drinks can hurt this system, says Laura Lagano, R.D., a New Jersey-based holistic nutritionist. (Discover more about the health benefits of teas such as chamomile, rosehip, or black tea.)
In 2009, King’s College researchers found that epicatechin may protect brain cells through mechanisms unrelated to its antioxidant ability, as epicatechin is one of the few flavonoids that can cross the blood-brain barrier. The King’s College researchers reported that somehow epicatechin protects brain cells from the negative effects of beta-amyloid plaques, although the exact mechanism of how this works is still not entirely know. (9)

Most Japanese teas are blended from leaves grown in different regions, with less emphasis on terroir than in the Chinese market. Because of the limited quantity of tea that can be produced in Japan, the majority of production is dedicated to the premium tea market. Bottled tea and tea-flavored food products usually use lower-grade Japanese-style tea produced in China.[57]
I'm a mom of two boys and live in Larkspur, CA, but still call South Africa my home. I grew up (literally) with Rooibos Tea: a naturally caffeine free beverage that has been used by generations of South Africans for anything from a delicious anytime drink, to a soothing beverage to calm Baby's colic, to putting in the bath for dry & flaky skin. You name it, Rooibos is the cure. 
There are also several harmful effects of green tea over-consumption that are possible. These include consuming tainted supplements marked as green tea extract, high caffeine consumption, consuming aluminum, and the effects of tea polyphenols on iron bioavailability. Green tea extracts should not be taken by patients suffering from renal failure, liver disease, heart conditions or major cardiovascular problems without supervision from a doctor. People sensitive to caffeine should be careful of their intake. Pregnant and breast-feeding women should drink no more than one or two cups per day, as some research shows that more caffeine than this amount may interfere with normal heart rhythms.

Matcha or maccha is a finely ground, bright emerald-green tea powder with the scientific name Camellia sinensis. It is prepared from a high-quality shade-grown leaf known as tencha. The tea bushes are sheltered to avoid the exposure of direct sunlight which reduces the pace of photosynthesis and slows down the growth of plants. This provides the leaves with a darker shade of green and stimulates the production of chlorophyll and amino acids.
A 2007 study concluded that green tea could hold promise as a new treatment for skin disorders such as psoriasis and dandruff. Researchers studied an animal model for inflammatory skin diseases, often characterized by patches of dry, red, flaky skin caused by the inflammation and overproduction of skin cells. Those treated with green tea showed slower growth of skin cells and the presence of a gene that regulates the cells' life cycles.
The risks associated with green tea are the same as those associated with any other kind of tea (common black tea, White Tea etc.) and are primarily due to the content of caffeine and tannin. The contraindications may vary with the percentage of caffeine and tannins in it. Most people might be familiar with these adversities, but it is still important to review and summarize the components responsible, as well as the associated risks.
Green is truly the color of health. Matcha helps to safely cleanse and purge the body of harmful elements. Chlorophyll the element that gives green tea and other plants their signature verdant color is also a powerful detoxifier, helping to eliminate both chemicals and heavy metals from the body. And because matcha is carefully shade-grown, it is substantially richer in chlorophyll than other green teas, making it a superior daily detox.
Believe it or not, green tea also helps people lose weight by enhancing the rate of metabolism, thereby promoting a faster consumption of the fat storage of the body. Recently, green tea has replaced many other beverages as it helps in weight loss. Drink a cup or two of green tea every morning and you are bound to lose a few pounds of excess weight over a week or so.
Along with caffeine, which gives green tea its characteristic taste, bitterness, and stimulating effect, green tea is also rich in a group of chemicals, called catechin polyphenols (commonly known as tannins, which contribute to bitter taste and astringency). These catechin polyphenols include catechin, epicatechin, epicatechin gallate (ECG), epigallocatechin gallate (EGCG), and various proanthocyanidins. They are also known as flavonoids and are very powerful antioxidants. Flavonoids, together with some amino acids like thiamine, are responsible for the potent flavor of green tea.
A study suggests that theanine found in matcha tea acts as a neurotransmitter. It exerts a calming effect on the brain without causing any drowsiness. This soothing effect helped the Buddhist monks in maintaining deep concentration during their meditation sessions and was the main reason behind its popularity. Another study has revealed the anti-stress effects of theanine present in this tea, which assists in reducing the physiological and psychological stress responses by inhibiting the neuron excitation. Matcha tea is also believed to boost memory and concentration.
