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.
Studies in laboratory animals have found that green tea polyphenols inhibit the growth of esophageal cancer cells (in line with its anti-cancer properties). Other clinical studies have found that green tea offers protection against the development of esophageal cancer, particularly among women. However, one large-scale population-based clinical study found just the opposite: drinking green tea was associated with an increased risk of esophageal cancer, and the stronger and hotter the tea, the greater the risk. It seems that if the water is very hot, it can damage the esophagus and lead to long-term adverse consequences. So just make sure the tea you drink isn’t extremely hot.

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.

All that being said, it should come as no surprise that I fell victim to the active marketing campaigns of one of the year’s biggest trends: fitness teas. You know what I’m talking about: stars and influencers like Kylie Jenner, Catherine Giudici Lowe, and Vanessa Hudgens are touting the successes of their respective experiences with fitness teas. These teas (by various brands) claim to eliminate bloat, cleanse your insides, and detoxify your organs. They claim to help you lose weight and curb cravings. Seriously? I thought as I scrolled through ad after ad. Sign. Me. Up.
The taste is of matcha is strong. Some people describe it as grass or spinach-like, and it has an umami taste. Because of this it may be sweetened to improve its palatability. One client was thrilled to tell me that he was drinking matcha, but instead of traditional matcha powder, he was drinking a powdered mix. The first ingredient was sugar, and it also contained powdered milk, so it was essentially like hot chocolate—but with cocoa swapped for matcha—something I wouldn’t recommend. Tea experts also warn that with matcha quality is key, and it comes at a cost. In other words, high quality, fresh, pure matcha is expensive. A low price tag can be a red flag for a poor quality product. I like Jade Leaf Organic Japanese Matcha Green Tea Powder ($19; amazon.com), because it's USDA certified organic, third party tested for contaminants, and from Japan.
Furthermore, green tea also contains amino acids such as theanine, butyric acid, and lignin; xanthine alkaloids such as adenine, dimethylxanthine, theobromine, theophylline, and xanthine; pectin (also found in fruits); saccharides (sugar), chlorophyll, and triterpene saponins. Vitamins, like vitamin A, B1, B2, B3, C, and E are also found in green tea. After that impressive list, perhaps you can begin to understand how packed green tea is with nutrients and beneficial components.

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?


The rooibos plant is endemic to a small part of the western coast of the Western Cape province of South Africa. It grows in a symbiotic relationship with local micro-organisms. Scientists speculate that climate change may threaten the future survival of the plant and the R600-million (approximately €43-million in March 2017) rooibos industry. Some claim that increasing temperatures and decreasing rainfall may result in the extinction of the plant within the next century.[15]
Today, an estimated 2.5 million tons of tea leaves are produced each year throughout the world, with 20 percent of that being green tea. Green tea didn’t become popular or widely distributed outside of Asia until about the early 1900s. China, other countries in Asia, countries in North Africa, the United States and Europe currently consume the most green tea worldwide.
10. Stop complaining for the next 100 days. A couple of years back, Will Bowen gave a purple rubber bracelet to each person in his congregation to remind them to stop complaining. “Negative talk produces negative thoughts; negative thoughts produce negative results”, says Bowen. For the next 100 days, whenever you catch yourself complaining about anything, stop yourself.

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.

Rooibos, also known as African red bush, grows near Cape Town, in the Cederberg region. To produce red tea, manufacturers harvest and chop the needle-shaped green leaves of the rooibos plants, which are then dampened and fermented for 12 hours. Once fermented, the leaves oxidize, turning red before they are dried and sold as loose or bagged tea. When steeped in hot water, the resulting liquid has a reddish-amber hue and an earthy taste that isn't bitter because it's low in tannins. You can drink it alone or with milk, sugar, honey or lemon. This somewhat astringent tea is rich in antioxidants, including quercetin, aspalathin and nothofagin, all of which have anti-inflammatory and calming properties, according to the "Journal of Agricultural and Food Chemistry," published in July 2009.
This tea is a rich source of antispasmodic agents, which can ease severe stomach cramps and abdominal pains. This is mainly due to the activation of K+ (potassium) ions in the body without antagonizing the activities of calcium, according to a report published in the Basic & Clinical Pharmacology & Toxicology. This can reduce the presence of hyperactivity in the gastrointestinal tract, thus preventing diarrhea and other intestinal issues.

Matcha tea has antioxidants such as catechins – EGCG (epigallocatechin gallate), which detoxifies the body. A research study assessing the antioxidant power of this tea has revealed that as compared to other green teas matcha has the highest amount of EGCG. These antioxidants seek out for the oxygen free radicals and neutralize their harmful effects. Thus, protecting the body from the occurrence of disorders or inflammations associated with the oxidative stress.
The next morning, I had a bagel and one daily tea, as instructed. I felt my stomach become uneasy as most stomachs do when they’re working their “digestive magic.” Suddenly, the worst cramp of my life hit me out of nowhere. It was the sharpest PANG I’ve ever felt as it made its way from my stomach to my chest. As a reflex, I jumped up. That’s when I felt another wave of pain and swiftly made my way to the restroom.

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 is loaded with a rare and powerful group of natural polyphenol antioxidants called Catechins that work to prevent oxidative damage to cells and reduce your risk of cancer* (1). According to the National Cancer Institute, the catechins in Matcha green tea are so powerful that they may actually reduce the risk of cancer, making Matcha green tea one of the top natural cancer treatment options out there.* (2)
“Specific detox teas offer added benefits in the additional ingredients,” says Villacorta. Herbs like lemongrass, ginger, dandelion, and milk thistle all contain properties said to support a healthy liver, one of those organs in charge of your natural detoxifying process. Ginger has also been proven to alleviate oxidative stress within the liver, which indirectly helps the organ perform its cleaning task more efficiently, he says.
These are some of the many benefits but the reality is one cup of tea a day will not give you all the abundant gains. The jury is out on how many cups are necessary; some say as little as two cups a day while others five cups. If you are thinking of going down this route, you may want to consider taking a green tea supplement instead (it would keep you out of the bathroom).
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.
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?
One-1/2 teaspoon serving of matcha, no more than once daily, is certainly a valuable addition to any diet, says Zeitlin. Like with another substance currently having a moment, turmeric, you can get your dose by eating or drinking it, though Zeitlin says drinking it as a tea, how it was initially intended, provides all the benefits without the added calories.

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.
One of the key components in Matcha is the amino acid L-theanine, which is found almost exclusively in shade-grown green teas like Matcha. When L-theanine is combined with the natural caffeine in tea, it metabolizes more slowly, releasing the caffeine over a longer period of time and providing a stable three to six hour long energy boost (versus coffee caffeine at an hour to an hour and a half).

In addition to actual tea, detox concoctions typically include additional herbs, which may be designed to curb appetite, rev metabolism, or boost weight loss in other ways. One example is senna, a plant with a natural laxative effect. According to the Natural Medicines Comprehensive Database, the potential side effects of senna use may include abdominal pain and discomfort, cramps, bloating, gas, nausea, and diarrhea; excessive use can lead to potassium depletion and other electrolyte abnormalities, which can trigger muscle spasms and an abnormal heart rhythm. Another popular ingredient in weight loss teas is guarana, a plant that's often added to energy drinks. Its side effects are commonly related to its caffeine content, which may include nervousness, restlessness, stomach irritation, nausea, vomiting, headache, anxiety, agitation, ringing in the ears, and fast heart and breathing rates. Bottom line: Do your homework about exactly what's in a product before you put it in your body. Even "all-natural" substances can have potential side effects, especially if they're overused, combined with other supplements or medications that result in negative interactions, or if taken by those with pre-existing medical conditions.

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.
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]
Green tea is claimed to have been popularized in Japan around 1190, when a Zen priest visiting and studying in China’s great Buddhist monasteries and temples returned to Japan with tea plant seeds and bushes. The young priest, called Eisai, used his experience growing and drinking tea in China to popularize the way of tea as a meditation ritual within his own community of Buddhist monks, eventually spreading the custom of tea drinking throughout the rest of Japan. To this day, China and Japan are the top two green tea producing and exporting countries in the world.
The first early harvest of tea, plucked before the first flush, is called shincha. Shincha is made from the youngest new growth leaves, and is plucked from early April to early May. Shincha typically refers to the early harvest of sencha, but can refer to any type of tea plucked early in the season, before the main harvest. Because of the limited quantities in which it is produced, shincha is highly prized and expensive to obtain.[66]
Another benefit of green tea it’s is lower in caffeine than most other teas, so you may be able to drink the five cups a day that lowered psychological stress in a large group of Japanese people in a recent study done at Sendai’s Tohoku University Graduate School of Medicine. The researchers didn’t identify any particular component of green tea that might have been soothing, but animal studies suggest that one compound, EGCC, had both sedative and hypnotic effects that tamp down the body’s production of stress chemicals.
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.
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.)
It’s important to point out that while it might be very beneficial, drinking green tea alone likely won’t improve your life span or protect you from disease. Research suggests that a combination of lifestyle components account for the health benefits observed in people that drink tea. The problem with many studies that investigate the effects of green tea is that they are population studies rather than controlled clinical studies, according to the Mayo Clinic. In many of these studies, other lifestyle factors and habits besides drinking green tea are not well-controlled, so it’s difficult to draw conclusions. Overall, studies have found a great number of health benefits of green tea, especially as it relates to anti-aging, but the bottom line is that the quality of your overall diet is really what’s most important.
The claims of weight loss within 14 days has worked for many users. V tea T-tox 14 Day Detox Tea works by boosting the body’s metabolism and suppressing appetite. Since it doesn’t have the natural laxative of senna leaves, you will be not be rushing to the washroom frequently. So, it is completely safe to take this tea to work or school for consumption later in the day.
