Liver problems have been reported in a small number of people who took concentrated green tea extracts. Although the evidence that the green tea products caused the liver problems is not conclusive, experts suggest that concentrated green tea extracts be taken with food and that people discontinue use and consult a health care provider if they have a liver disorder or develop symptoms of liver trouble, such as abdominal pain, dark urine, or jaundice.
If you do choose to try a tea detox, the most important aspect isn't the kind of healthy tea you choose—it’s what else you eat: “Tea can only be medicinal and detoxifying if your diet isn’t taxing your system, which most American meals are guilty of,” says Lagano. In order to truly detoxify your body, cut processed and fried foods, and up your intake of fruits, vegetables, whole grains, lean proteins, and anti-inflammatory fats like avocados and almonds, says Villacorta. Once your diet is clean and gentle on your body, detoxifying teas can begin to enhance your natural organ function.

In response, the governor of Shizuoka Prefecture, Heita Kawakatsu, stated: "there is absolutely no problem when they [people] drink them because it will be diluted to about 10 becquerels per kilogram when they steep them even if the leaves have 1,000 becquerels per kilogram;" a statement backed by tests done in Shizuoka.[35] Japanese Minister for Consumer Affairs and Food Safety Renhō stated on 3 June 2011 that "there are cases in which aracha [whole leaves of Japanese green tea] are sold as furikake [condiments sprinkled on rice] and so on and they are eaten as they are, therefore we think that it is important to inspect tea leaves including aracha from the viewpoint of consumers' safety."[36]
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.
The detox period lasts for about 30 days, and most companies recommend taking a significant break (around six weeks) between detox sessions if you plan to do it more than once. Many detox tea companies are also quick to note — in small print, of course — that their teas are not suitable meal replacements and are meant to be used in conjunction with healthy eating and regular exercise.
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.
Hi, my name’s Abby. I’m a 23-year old writer and copy editor here at The Everygirl, and I’ve had a love-hate relationship with my body for as long as I can remember. I’m a slave both to the gym and to Taco Tuesday. I’m happiest in a spin class, but I also make the best pumpkin muffins you’ve ever tasted (full of fat, full of sugar, and full of love). I love taking care of my body, but I also LOVE food.

Even organically grown green teas have been shown to contain lead, which is absorbed by the plant from the environment, particularly tea grown in China. When traditional green tea is steeped, about 90% of the lead stays in the leaf, which is discarded. With matcha, since the whole leaf is consumed, you will ingest more lead. One independent group, ConsumerLab.com, which tested teas, estimates that a cup of matcha may contain as much as 30 times more lead than a cup of green tea. Therefore, they recommend drinking no more than one cup daily, and not serving it to children.
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.
A book written by Lu Yu in 600-900 AD (Tang Dynasty), "Tea Classic" (simplified Chinese: 茶经; traditional Chinese: 茶經; pinyin: chájīng), is considered important in green tea history. The Kissa Yojoki (喫茶養生記 Book of Tea), written by Zen priest Eisai in 1211, describes how drinking green tea may affect five vital organs, the shapes of tea plants, flowers and leaves, and how to grow and process tea leaves.
Matcha tea works wonderfully well in providing a calming effect on the body. L-theanine, a unique amino acid present in this green tea, possesses anti-anxiolytic properties, which assists in boosting alpha waves in the brain. These alpha waves enhance mood, encourage relaxation, induce a profound feeling of mental clarity, and help achieve an alert state of mind.

As an additional benefit, L-Theanine may help memory and learning and ability all the while inhibiting any possible side-effects from caffeine, a natural component of green tea. Therefore, a bowl of matcha promotes concentration and clarity of mind without any of the nervous energy found in coffee. Try matcha as a pick-me-up for the afternoon or anytime you need extra focus.

In 1772, Swedish naturalist Carl Thunberg noted, "the country people made tea" from a plant related to rooibos or redbush. Traditionally, the local people would climb the mountains and cut the fine, needle-like leaves from wild rooibos plants.[citation needed] They then rolled the bunches of leaves into hessian bags and brought them down the steep slopes using donkeys. The leaves were then chopped with axes and bruised with hammers, before being left to dry in the sun.
When I was conducting research into South Africa’s native herbs, I was served rooibos everywhere I went. Red in the cup, fragrant to the nose and pleasing to the palate, rooibos soon became a favorite. In every meeting, I looked forward to that red tea, which is one of the only native herbs of South Africa to achieve significant commercial status.  My wife and I keep it in the tea cupboard at home, and we often turn to rooibos when we want a cup of tea without caffeine.
Day 3: As I started to make my 5th cup in 3 days, my best friend said, “Ab, I really don’t think you should be drinking so much of this stuff. Why don’t you just stick to the recommended amount?” I responded with “It’s just TEA — what’s the worst that could happen?” On day 3, I learned. I had decided to give up coffee during my 28 days, both as a way to save my sanity and excretory system and as a way to wean myself out of my coffee habit. That was really stupid. By day 3, I was experiencing a horrifying caffeine headache and a rough case of the spins. I was also literally exhausted and finally feeling the ~desired effects~ of the detox (frequent trips to the bathroom, to put it lightly), so I was dealing with an excess of that on top of my other horrible side effects. Do I blame the tea? Not even a little. I blame myself for overindulging in too much of a good thing. From there on out, I decided to follow the rules.
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.

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)

Maturitas (Review). 73 (4): 280–7. doi:10.1016/j.maturitas.2012.08.008. PMID 22986087. 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.

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.


"Drink tea if you enjoy it, in moderation, and not because you're taking it as a medicine," says Dr. Sesso. Stirring in a little sugar is fine, but if you add a few heaping teaspoons of sugar, you're probably canceling out tea's possible benefits, he notes. And beware of the sugar found in many bottled teas, some of which contain as much as nine teaspoons of sugar per serving—almost as much as colas and other soft drinks. Check bottled tea labels and choose only pure, unadulterated tea—or save money and brew your own at home.
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 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.
Basically, tea time may not be for you. I know we all want “quick results,” but instead a gradual change in diet is best. Since my last tea scare, I’ve actually gotten accustomed to simply eating better. Stuff like eliminating dairy has helped with my “fupa” (lower belly pudge), and overall bloat. Limiting my red meat intake has also helped. Leaner meats like turkey, chicken breast and egg whites have helped me keep inches off and feel more energized.
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 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.
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.
What are the health benefits of black tea? Black tea is a popular drink worldwide. Polyphenols and other ingredients may make tea drinking not only a pleasant social ritual, but good for health, too. It may help beat stress, boost thinking, decrease cancer risk, and reduce arthritis. However, too much can cause heart arrhythmias. Find out more. Read now
Rooibos is especially rich in the super-antioxidant compound quercetin. A titan among the antioxidants, quercetin imparts benefits to the heart, helps to reduce the risk of various types of cancers, fights viruses and is significantly anti-inflammatory. Inflammation is part of all known chronic degenerative diseases. The anti-inflammatory activity of quercetin means that it helps to reduce the risk of many types of health disorders.

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]
