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.


Rooibos grades are largely related to the percentage "needle" or leaf to stem content in the mix. A higher leaf content results in a darker liquor, richer flavour and less "dusty" aftertaste. The high-grade rooibos is exported and does not reach local markets, with major consumers being the EU, particularly Germany, where it is used in creating flavoured blends for loose-leaf tea markets.
Rooibos is sometimes used as substitute for milk with colicky babies, says Alvaro Viljoen, PhD, of the department of pharmacy at the University of the Witwatersrand. And the health benefits of Rooibos are bound to make it a favorite, he says: rich in antioxidants, rich in vitamin C, caffeine-free, and low in tannins, the residue in teas that can sometimes cause digestive problems.

We believe that if you’re going to do something, you should do it right. That mentality took us around the world in search of the best Matcha. We eventually landed in Japan, where we found some of the brightest green powder we had ever seen. Japan has warm weather, and receives plenty of sunlight and rain — all of which make it an ideal climate in which to grow leaves. 

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.

Did the detox tea drastically change my life? No. But did it reduce bloat, give me some new confidence, and taste great in the process? Yes. If you’re looking for a quick solution to lose weight, this is not for you. But if you’re looking for a delicious supplemental addition to a consistent workout regimen and a healthy diet, this IS for you. Don’t expect the tea to do all the work for you, but expect it to work with you — helping you out wherever you’re at on your journey to your healthiest self.
With the day-to-day stress that life throws our way, it's essential to stock up on self-care items to stay healthy, invigorated, and relaxed. Incorporating a cup of healthy detox tea into your daily regimen can bring significant health benefits, from boosting your immune system to detoxifying the liver after those holiday parties and whiskey cocktails. Here are our picks for detox tea cleanses you should be sipping this season.
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]

Because matcha is prone to clumping (that’s why you’ll see instructions to sift it before whisking in the water or milk), you’ll want to take the same precaution in your baking experiments: Saffitz suggests combining the matcha with other dry ingredients like sugar or flour to avoid bitter lumps in your dough or batter. And use it sparingly, she suggests: Even a few teaspoons can create an intense flavor (and color).

Because matcha is incorporated into water (whereas other green teas are steeped in water), you consume the entire leaf—and thereby the full effects of its antioxidants, vitamins, and caffeine. Fans say matcha provides a calmer, more sustained energy burst than coffee or espresso, and since it’s less astringent, it mingles more readily with fruit, yogurt, and herbs in wake-up drinks like smoothies and juices.


As everyday impurities find their way into our bodies, we may be left feeling tired or out of balance. Yogi DeTox tea combines time-honored cleansing herbs Burdock and Dandelion with Juniper Berry and an Ayurvedic blend called “trikatu” (Ginger, Black Pepper and Long Pepper), traditionally used to support digestion and circulation. Indian Sarsaparilla, Licorice, Cinnamon, Cardamom and Clove round out this delicious blend for a perfectly spiced tea. As part of an overall wellness program, Yogi DeTox tea helps bring healthy balance from within.*
The oldest tea producing region in Japan is Uji, located near the former capital of Kyoto.[50] It is thought that seeds sent by Eisai were planted in Uji, becoming the basis of the tea industry there.[51] Today, Japan's most expensive premium teas are still grown in Uji.[52] The largest tea producing area today is Shizuoka Prefecture, which accounts for 40% of total Japanese sencha production.[53][52] Other major tea producing regions include the island of Kyushu and the prefectures of Shiga, Gifu, and Saitama in central Honshu.[52]

Rooibos tea is anti-inflammatory in nature, which means that it reduces blood pressure and scavenges free radicals like other antioxidants. Quercetin, another powerful antioxidant found in rooibos tea, has been linked to preventing a wide variety of heart conditions. It promotes an increase in HDL cholesterol (good cholesterol) and inhibits the LDL cholesterol (bad cholesterol) from binding to the walls of arteries and blood vessels.
Domestic Process: This is a very simple process. It involves repeated steeping of tea in hot water and the disposal of the water (you may use this tea to serve those who don’t mind having caffeinated tea). The more you repeat the process, the less caffeine there will be left in the tea, but the same is true of the taste and flavor. Basically, don’t overdo it. Two or three steepings are probably safe. After all, you do want tea and not plain, hot water, right?
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.

Matcha, like other green teas, contains a class of antioxidants called catechins. Matcha is high in a catechin called EGCG (epigallocatechin gallate), which is believed to have cancer-fighting effects on the body. Studies have linked green tea to a variety of health benefits, like helping to prevent heart disease, type 2 diabetes and cancer, and even encouraging weight loss. However, it’s important to note that much of this research isn’t from clinical trials that show green tea causes a benefit. Instead, it’s largely from population-based studies, where researchers look at groups of people who drink green tea and compare their health outcomes to groups that don’t drink it. Studies have shown associations between tea and better health, but causation is not yet proven. Matcha is even less studied than brewed green tea.

Word of Caution: Despite all of these health benefits of rooibos tea, there can be a downside for some people. Since rooibos is so powerful, it can interfere with treatments for various conditions, including chemotherapy for cancer patients. Also, rooibos has shown estrogenic activities in certain studies, so it might not be a good idea to use if you have hormone-sensitive cancer like breast cancer.
I boil 8oz of water and put 2 tea bags in at night. If I feel very bloated when I wake up, I boil another 8oz of water and put 2 tea bags in. If you are trying to lose weight, I HIGHLY recommend drinking this tea at night. I feel amazing when I wake up in the morning. I was able to lose 60 pounds and I owe a lot of it to this tea for taking the extra bloating and the edge off. I really enjoy drinking it at night too because it soothes me, and I feel like it helps my body burn more fat as I sleep.
Short-term studies have shown that drinking tea may improve vascular reactivity—a measure of how well your blood vessels respond to physical or emotional stress. There's also evidence that drinking either black or green tea may lower harmful LDL cholesterol levels. Blood pressure may also dip slightly in people who drink tea, but results from these studies have been mixed.
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.[citation needed]

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.


This cleansing tea also contains appetite-suppressing ingredients including yerba mate, guarana and damiana (1), so you can enjoy a cup any time you want to quell your hunger, and in place of unhealthy snacks. Also includes powerful and highly beneficial organic green tea, oolong, ginger, pomegranate and more. Take a sip of paradise and reach your goals at the same time!

One detox tea brand, recently Instagrammed by Amber Rose, advises per their website that for "best results," the tea should be consumed along with plenty of water, healthy, balanced meals, and three to five workouts a week. Another, which has been Instagrammed by several celebs, including Kourtney Kardashian, Christina Milian, and Hilary Duff, states online that the tea "is recommended to be taken in conjunction with a healthy energy-controlled diet and regular exercise" and the website offers an accompanying meal plan for sale. Personally, I'd love to see a study comparing outcomes generated by a detox tea compared to a placebo, with both groups following the exact same eating plan, but I haven't found any. That makes it difficult to know whether the weight-loss results people are getting from these teas are actually due to drinking them, or simply the result of' a cleaned-up diet and consistent workout routine, which we already know can lead to weight loss. In any case, simply sipping detox tea while continuing to skip the gym and order takeout is unlikely to help you shrink your shape. 

Unlike traditional green tea, matcha preparation involves covering the tea plants with shade cloths before they’re harvested. This triggers the growth of leaves with better flavor and texture, which are hand selected, steamed briefly to stop fermentation, then dried and aged in cold storage, which deepens the flavor. The dried leaves are then stone-ground into a fine powder.
Green tea can lower and help stabilize your blood sugar levels (glucose levels); in fact, studies show that green tea can even improve insulin sensitivity and reduce blood sugar levels. One study among Japanese individuals found that those who drank the most green tea had a very significantly lower risk of developing type II diabetes. Other studies have shown similar results.

Every day, countless people throw away valuable antioxidants and minerals. While seemingly unimaginable, that’s exactly what happens when you brew a cup of green tea because water can only extract a fraction of green teas benefits. The majority actually remains unused, trapped in the tea leaves. In reality, the only way to truly take advantage of green teas full potential is to consume the entire leaf. But that doesn’t mean you need to start eating tea leaves. The simplest solution is to just enjoy a bowl of matcha. Because matcha is straight, stoneground tea leaves, matcha provides you with green teas powerful arsenal of vitamins, minerals, antioxidants, and amino acids in a way no other green tea can.


I’ve been taking these for a few days now and saw immediate results on the first day, my liver started hurting less and now it doesn’t hurt at all. I also noticed my face looked healthier and got that famous “glow” I only drink 1 cup a day because if I’m going to be completely honest, I’m not a big fan of the taste, but since it’s actually helping me, I don’t mind.
Instead of being rolled, shaped and dried like traditional green tea leaves, the leaves destined to become Matcha are laid flat to dry. Grinding the leaves into Matcha is a slow process. If the mill stones overheat, the delicate green tea leaves might become damaged, which alters the flavor and taste. For reference, it takes about one hour to grind 30g of Matcha. 

Indigenous to the Western Cape of South Africa, rooibos (Aspalathus linearis) is a shrub with long, needle-shaped leaves that turn red upon fermentation. When you drive through the countryside north of Cape Town, you see rooibos everywhere. Rooibos is a traditional beverage of the native Khoi people of the Cape area, though it has become more popular in recent years due to word spreading about its high antioxidant value. Traditionally, the native people harvest the leaves, bruise them with hammers, ferment them and dry them. The result is a red, astringent tea that refreshes and does not cause jitters.
Most detox tea blends contain 60 milligrams or more of caffeine, which is less than a cup (eight ounces) of black coffee, which packs about 95 milligrams of caffeine. But it’s the combination of caffeine with other ingredients, like nettle leaf and dandelion leaf, that could upset your stomach and force you to take even more bathroom breaks, especially if you’re predisposed to stomach sensitivity or gastrointestinal issues.
In 2004, scientists at the University of Newcastle studied the effects of black and green tea on Alzheimer’s disease. In laboratory studies, both teas prevented the breakdown of acetylcholine, the neurotransmitter strongly linked with memory. The teas also inhibited enzymes known as BuChE and beta-secretase. These enzymes are found in protein deposits found in the brain of Alzheimer’s patients. (7)

Dr Nortier cultivated the first plants at Clanwilliam on his farm Eastside and on the farm Klein Kliphuis. The tiny seeds were very difficult to come by. Dr Nortier paid the local villagers £5 per matchbox of seeds collected. An aged Khoi woman found an unusual seed source: having chanced upon ants dragging seed, she followed them back to their nest and, on breaking it open, found a granary.[12] Dr. Nortier's research was ultimately successful and he subsequently showed all the local farmers how to germinate their own seeds. The secret lay in scarifying the seed pods. Dr Nortier placed a layer of seeds between two mill stones and ground away some of the seed pod wall. Thereafter the seeds were easily propagated. Over the next decade the price of seeds soared to an astounding £80 a pound, the most expensive vegetable seed in the world, as farmers rushed to plant rooibos. Today, the seed is gathered by special sifting processes. Dr Nortier is today accepted as the father of the rooibos tea industry. Thanks to his research, rooibos tea became an iconic national beverage and then a globalised commodity. Rooibos tea production is today the economic mainstay of the Clanwilliam district. In 1948 The University of Stellenbosch awarded Dr Nortier an Honorary Doctorate D.Sc (Agria) in recognition for his valuable contribution to South African agriculture.
Evidence pointing to a boost exists in abundance. But first, let’s clarify what matcha is to begin with — in case you were trapped under something heavy these past few years. It’s basically green tea, derived from the leaves of the Camellia sinensis plant, finely ground. Oxford’s Living Dictionary cites its origins in Japan as a combo of two terms, “from matsu ‘to rub’ + cha ‘tea’, from Chinese (Mandarin dialect) chá (see tea).” Matcha masters House of Matcha say the beverage is steeped in history. “Samurai warriors drank matcha green tea before going into battle because of its energizing properties, and Zen Buddhist monks drank it as a way to flow through meditation while remaining alert,” reads the website.
Slimming tea: Does it work and is it bad for you? Slimming teas have become increasingly popular in recent years. They aim to suppress the appetite, reduce fat, or boost the metabolism. However, while weight loss may result, this is largely due to fluid loss. The use of these teas remains controversial, and people are encouraged to use other methods of weight loss. Read now

Like black and green tea, rooibos is rich in polyphenols, such as rutin and quercetin. Cell and animal studies, mostly from South Africa, have shown that rooibos extracts have antioxidant, immune-stimulating, and anti-cancer properties. But studies of rooibos tea in people are limited. There’s little or no evidence to back claims that it relieves constipation, headaches, eczema, asthma, insomnia, high blood pressure, mild depression, ulcers, diabetes, and so on.
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.[2]
Ceremonial grade: Ceremonial grade is the highest quality matcha from the most carefully cultivated buds and leaves. Ceremonial grade is given the most attention to detail during processing to yield the freshest, most delicate tasting, and smoothest ground matcha. Ceremonial grade is meant to be enjoyed on its own, with no other sweeteners or additives, to really enjoy and appreciate the intended flavor.

The important thing to note here is that what we refer to as red tea in our shop and what is called red tea in China would be referred to as black tea in most other countries. The distinction in color depends on whether you are talking about the color of the leaves or the color of the brew. The color of the brew is typically a beautiful amber, red color thus leading to the name “red tea”. The color of the leaves though are typically dark black, thus leading to the name “black tea”. Thus the terms can be used interchangeably. Red tea is oxidized/fermented for about 6-10 hours until the leaves turn an amber/black color and then they are dried to stop the oxidation process.
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.
Clinical studies suggest that green tea may boost your metabolism and help you burn fat. Green tea can also help you lose weight and lower your risk of becoming overweight or obese. Much of this effect is likely due to caffeine, but other compounds in tea may also contribute to this effect. By helping you selectively burn the fat you have stored in your body for energy, green tea may help you feel fuller and maintain a more steady energy level, resulting in less hunger cravings and less calories consumed.

Matcha tea rich in EGCG  helps fight various bacterial, viral, and fungal infections. According to a research study,  EGCG binds to the lipid membrane and exerts inhibitory action against the growth of various human pathogens. These include influenza A virus, hepatitis B, and C virus, herpes virus, adenovirus Staphylococcus aureus bacteria, and Candida albicans yeast.
Observational studies found a minor correlation between daily consumption of green tea and a 5% lower risk of death from cardiovascular disease. In a 2015 meta-analysis of such observational studies, an increase in one cup of green tea per day was correlated with slightly lower risk of death from cardiovascular causes.[13] Green tea consumption may be correlated with a reduced risk of stroke.[17][18] Meta-analyses of randomized controlled trials found that green tea consumption for 3–6 months may produce small reductions (about 2–3 mm Hg each) in systolic and diastolic blood pressures.[18][19][20][21] A separate systematic review and meta-analysis of randomized controlled trials found that consumption of 5-6 cups of green tea per day was associated with a small reduction in systolic blood pressure (2 mmHg), but did not lead to a significant difference in diastolic blood pressure.[22]
It’s become such a fashionable beverage that, last summer, the New York Post ran a story about how Victoria’s Secret models were flocking to Cha Cha Matcha, a hipster spot fluent in the preparation of various matcha-based miracle potions. A search for where to get “matcha” in New York, New York on Yelp yielded some 1400 plus results. Even mass market coffee purveyors like Starbucks have made matcha their mantra, with a vast range of offerings to cash in on the craze.
When my tea arrived in the mail, I was hyped. Clearly, packaging is a major key for fancy weight loss teas. I purchased the cutesy infuser that I needed to steep loose-leaf tea, along with a tumbler that allowed for on-the-go steeping. I got a 30-day detox package which included 15 nighttime teas, which you’re supposed to drink every other night and 30 gentler daily teas you drink in the mornings.
I boil 8oz of water and put 2 tea bags in at night. If I feel very bloated when I wake up, I boil another 8oz of water and put 2 tea bags in. If you are trying to lose weight, I HIGHLY recommend drinking this tea at night. I feel amazing when I wake up in the morning. I was able to lose 60 pounds and I owe a lot of it to this tea for taking the extra bloating and the edge off. I really enjoy drinking it at night too because it soothes me, and I feel like it helps my body burn more fat as I sleep.
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.
Other Risks: Long-term consumption, in excessive quantities, may give rise to problems such as insomnia, restlessness, annoyance, irritability, headaches, hypertension, abnormal heartbeat, loss of appetite, spasms, constipation, and acute addiction to caffeine. Many times, people who are addicted to caffeine do not feel normal without the substance and suffer from acute constipation, irritation, and lack of concentration in the absence of green tea.
What I will tell you is that there are a LOT of options for these fitness teas. I did a lot of research before purchasing one, so my best advice to you is to make yourself a list of available options (see below), determine what you hope to gain from the experience (see even further below), and then research the specific ingredients for yourself. Here’s the moral of the story: They’re all very similar, but it’s important to be aware of what you are personally putting in your own body. Disclaimer: What works for one may work differently for another — so take your research seriously.
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]
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.

Scientists have also discovered that the antioxidants flavonoids may also protect the brain from oxidative stress. The scientists extrapolated that a human would need to drink about three liters of liquid infused with 0.5 percent of the catechins to get similar effects. However, because humans ingest other antioxidants in the form of vitamins and plant polyphenols, it’s likely that a much lower quantity could be effective in protecting memory.

• One Chinese study found that men who drank more than three cups of tea a day reduced their risk of prostate cancer by 70 percent. In another study funded by the National Institute of Health, 79 men with prostate cancer were told to either drink 6 cups of green tea a day or 6 cups of water. After 3 to 8 weeks, the levels of prostate-specific antigen, a protein that may indicate cancer, were lower in the men who drank green tea than those who drank water. An indicator of inflammation, nuclear factor-kappaB, linked to cancer growth, was also lower in the men who drank the green tea.
