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.

But ConsumerLab.com’s testing has found that even if lead is found in the leaves used in green tea bags, it doesn’t appear to be absorbed into the water. Cooperman says his team was concerned about lead content in matcha, because people consume the ground green tea leaves directly rather than in bags. However, their testing showed that among the six popular matcha brands they tested—DoMatcha, Encha Organic Matcha, Rishi Teahouse Matcha, Teavana Imperial Matcha, Kirkland Signature Green Tea and The Republic of Tea Double Green Matcha Tea—the powders were not contaminated by lead or other metals, and also did not contain pesticides. As of now, Cooperman says he doesn’t believe lead exposure is a risk in the matcha currently sold in the United States.
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.
I should note that I am currently deployed and have little access to the facilities to make a great cup of tea. One of the great things about matcha however is that you need only a blender bottle and ice and you have a perfect iced matcha for the Iraq heat. Let me tell you, nothing like the grassy, subtly sweet taste to get your morning started right. PT? Matcha. Drills? Matcha. conducting a firefight with Islamic State extremists? Hasn't happened yet, but if it happened I can tell you that I would have my Hydroflask filled with this stuff and engage them with the calm energy of the vegan, philosophy major, Prius-driving, non-binary person I am.
Still, there have been some interesting findings. A 2014 study looked at 25 randomized controlled trials on the link between tea and blood pressure and reported that when people drank tea—especially green tea—for 12 weeks, their blood pressure dropped significantly. A 2011 study reported that drinking green tea appeared to be linked with lower levels of bad LDL cholesterol, but more research is needed. Because matcha is a type of green tea, they may share similar benefits, but there’s not enough research to make that claim.

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.

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.
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,[11]) 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[12] (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:[13]

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.[23][22][26] 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.[23]
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.

2. Lemon or ginger tea: This revitalizing tea is great for the morning because the light amount of caffeine will wake you up without wreaking havoc on your stomach. Plus, the health benefits of ginger include reducing inflammation and controlling blood sugar, so you can feel good drinking this soothing tea. (Twining’s Lemon & Ginger, $3; twiningsusa.com)
Green tea leaves are initially processed by soaking in an alcohol solution, which may be further concentrated to various levels; byproducts of the process are also packaged and used. Extracts may be sold in liquid, powder, capsule, or tablet form.[4] Decaffeinated versions are also available.[9] Green tea extract supplements are accessible over the counter in various forms.[10]
Because matcha preparation uses ground tea leaves that cannot be removed after steeping, the caffeine content in a cup of matcha is much higher than that of a cup of tea prepared using tea bags or leaves. However, the exact caffeine content may vary depending on the ratio of water to matcha powder used. Matcha contains less than half the amount of caffeine per cup than in a similar-sized cup of coffee.
In China though, the term black tea or dark tea typically refers to a tea that we call Pu-erh in the United States. This tea is fermented anywhere between 2 weeks to two months and then aged for 2 months to 20+ years in order to create dark black leaves and a dark color to the brew. In this fermentation process the leaves are intentionally kept damp to encourage good microbes and bacteria to slowly oxidize and ferment the leaves. This is distinguished from red tea which typically only takes about 6-10 hours to oxidize. Pu-erh tea typically has a strong fermentation taste but high quality pu-erh should not taste overly earthy as this is a sign of low quality production techniques.
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] 

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:

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.

For centuries, burdock has been used therapeutically in parts of Asia, Europe, and North America. A known diuretic, it stimulates digestion and can be used to treat kidney and liver ailments. Research has shown that compounds in the root contain antidiabetic and antioxidant qualities, and it also helps to promote blood circulation on the skin’s surface, which improves skin texture and helps to prevent eczema.

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]
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.
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.
Day 2: I hopped out of bed, made my 2nd cup of tea, then went about my day. As the hours wore on, though, I grew discouraged. The reviews I had read and testimonials from friends had assured me that the tea was going to start working its magic very quickly, but my stomach still felt perfectly normal and average. Since I am the perfect blend of spontaneous, self-destructive, and optimistic, I went ahead and made myself my 3rd cup in 24 hours (Remember that last night I drank it at night instead of the recommended first-thing-in-the-morning.).
The antioxidants present in rooibos tea slow down the aging process and also boost the strength of the immune system. Researchers at Nelson Mandela Metropolitan University in South Africa found that the local herb helps slow down the degeneration of fat cells, thus inhibiting the formation of wrinkles. Antioxidants in the tea seek out free radicals that damage the skin, hair, bones, and other organ systems by making them vulnerable to diseases and degeneration.
You’ve probably heard a lot about the health benefits of drinking tea, especially the benefits of green tea, considered by many to be the ultimate “anti-aging beverage.” In Okinawa, Japan — one of the world’s “Blue Zones” that’s associated with longevity —drinking green tea daily is considered “essential.” (1) A popular practice is sipping on a combination of steeped green tea leaves, jasmine flowers and a bit of turmeric throughout the day.
Although research on the specific health benefits of matcha is limited, some studies suggest that regular consumption of green tea, in general, may help protect against certain health conditions. For instance, green tea appears to prevent age-related cognitive impairment, reduce LDL cholesterol, and reduce the risk of osteoporosis and other conditions such as prostate cancer.

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]

Like gyokuro, matcha is shaded before plucking. The plucked and processed leaf is called tencha. This product is then ground into a fine powder, which is matcha. Because the tea powder is very perishable, matcha is usually sold in small quantities. It is typically rather expensive.[62] Matcha is the type of tea used in the Japanese tea ceremony. It is prepared by whisking the tea with hot water in a bowl, until the surface is frothy. If the water is too hot, the tea may become overly bitter.[64]
One of the biggest buzz words in nutrition, antioxidants are naturally occurring chemical compounds that prevent aging and chronic diseases. Nowadays, a variety of fruits and vegetables are lauded for their antioxidant properties, leading to a host of products with all kinds of claims. But matcha is unparalleled in comparison. Firstly, matcha is packed with exponentially more antioxidants according to the latest innovation in antioxidant research.
Matcha tea powder is ground from fine Japanese green tea leaves. It is the star of the centuries-old Japanese tea ceremony, and its pleasant taste and health benefits make it a favorite of many tea-lovers today. Organic matcha green tea powder is whisked in a bowl with hot water to create a frothy, bright green, nourishing beverage. Once prepared, it is then immediately consumed in its entirety. It’s important to know where to buy the best quality Japanese matcha powder and tea bags. We take great pride in offering only top-quality matcha tea powder for your drinking pleasure.
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).
Caffeine: Everyone knows that caffeine is an external stimulant and raises blood pressure, and is actually toxic in nature (it may be fatal for some animals). Caffeine is also addictive and can have adverse effects on the liver and internal organs over the course of many years. That being said, it is the component of tea which makes it energizing and refreshing, which is why people are willing to risk it.

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. 
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.
Sometimes given to babies suffering from colic, rooibos is known for anti-spasmodic activity. A growing body of evidence suggests that the health benefits of rooibos may be quite broad, including evidence that the antioxidants in the tea may reduce the risk of heart disease, and may inhibit some parameters of aging. Rooibos even shows use as a cosmetic ingredient for soothing, protecting and repairing skin.
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).
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.

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.

Even with negligible evidence that matcha can boost a weight-loss regimen, the substance remains heavily endorsed. Philadelphia-based nutritionist Marjorie Cohn regularly enjoys matcha, adding it to her smoothies and chia seed pudding — even mixing it into her recipe for organic vanilla ice cream. She often recommends it to clients looking to cut out coffee, or to “hard core caffeine addicts” prone to reaching for a second or third cup of coffee.


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.
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.
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.)
Houjicha: Also spelled as “Hojicha”, this is not a pure or absolute green tea. Rather, it is a mixture of green tea and powdered roasted cereals such as wheat, barley, or rice. The quality and price of this variety depend upon the percentage or ratio of green tea to cereal content. The better ones, which have more green tea in them, are more expensive and have a greener look when brewed; on the other hand, those with higher grain contents yield a golden brown color and are cheaper.
According to the EMT, I had experienced the side effects of a Valsalva Maneuver. A Valsalva Maneuver is a forceful attempted exhalation against a closed airway. I had tried to force a push during one of those painful pangs I felt earlier. This caused an internal strain, resulting in a drop of my heart rate. The pain of the cramps had knocked the wind out of me. Had I been older and/or had a history of heart disease, I could have died. Common? No. Possible? Absolutely.
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.
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."
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.
